Abstract

Described herein is a method of editing a pleiopluripotent stem cell genome. In typical embodiments, an integration target recognition site (i.e., attB or attP site) is incorporated (i.e., beacon placement) into a pleiopluripotent stem cell genome by delivering into the cell a gene editor (or a prime editor fusion), attachment site-containing guide RNA (atgRNA), and, optionally, a nicking guide RNA (ngRNA). Further, integrating a donor polynucleotide template into the pluripotent stem cell genome at the incorporated target recognition site is described herein thereby producing a genetically modified pluripotent stem cell.

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims the benefit of U.S. Provisional Application No.63/391,659, filed July 22, 2022 and U.S. Provisional Application No.63/375,190, filed September 9, 2022; each of which is hereby incorporated in its entirety by reference. 2. SEQUENCE LISTING [0002] The instant application contains a Sequence Listing with 667 sequences, which has been submitted via Patent Center and is hereby incorporated by reference in its entirety. Said XML copy, created on July 21, 2023 is named 52810PCT-sequencelisting.xml, and is 918,523 bytes in size. 3. BACKGROUND [0003] Programmable, efficient, and multiplexed genome integration of large, diverse DNA cargo independent of DNA repair remains an unsolved challenge of genome editing. Current gene integration approaches require double strand breaks that evoke DNA damage responses and rely on repair pathways that are inactive in terminally differentiated cells. Furthermore, CRISPR-based approaches that bypass double stranded breaks, such as Prime editing, are limited to modification or insertion of short sequences. [0004] There is a need in the art for techniques and gene editor compositions and gene editor guide RNAs which address and overcome these shortcomings and enable the programmable genomic integration of a large gene(s) in pluripotent stem cells. 4.

[0229] FIG.24 shows a non-limiting example of the clonal isolation process for generating an iPSC clone. The overall process takes roughly a month from electroporation to NGS analysis. First, electroporation (EP) is used to place beacons in the iPS cells. Electroporated iPSCs are grown for 72 hours and part of the iPSC culture is harvested for genomic DNA to get an initial read of beacon placement. If cells are positive for beacon placement, electroporation is scaled up from a 48 well plate to a 24 well plate and then eventually to 6 wells. A confluent 6 well population of cells is diluted such that a single cell is placed in each well of a 96-well plate across multiple 96 well plates. These cells take roughly two weeks to reach the point of needing to be harvested. Cell growth is monitored and only clones with good morphology and growth rates are expanded and/or harvested for a second round of ddPCR. Cells with high performing beacon placement (e.g., beacon placement at both the TRAC and AAVS1 loci) are scaled up a final time to 6 well plates. The last step being to send samples for NGS analysis and cryopreserve the remaining cells. [0230] FIG.25 shows next generation sequencing data from iPSC clones generated using the method described in FIG.24.

Each donor polynucleotide template includes an AttP site having a different central dinucleotide that enables integration at its corresponding (cognate) AttB site that has been site-specifically integrated into the iPS cell genome at one of the indicated loci. Controls include no BxB1 control (i.e., donor polynucleotide templates but no BxB1) and a no donor polynucleotide template control (i.e., a BxB1 polypeptide or polynucleotide encoding a BxB1 polypeptide but no donor polynucleotide templates. [0232] FIG. 27 shows ddPCR data for programmable gene insertion of four different donor polynucleotide templates at the B2M, CIITA, TRAC, and AAVS1 loci in iPSC clones #30. Each donor polynucleotide template includes an AttP site having a different central dinucleotide that enables integration at its corresponding (cognate) AttB site that has been site-specifically integrated into the iPS cell genome at one of the indicated loci. 6. DETAILED DESCRIPTION OF THE INVENTION [0233] In one aspect, the methods described herein enable multiplexed programmable gene insertion whereby multiple edits (e.g., beacon placement, donor polynucleotide incorporation, or a combination thereof) can be performed sequentially or simultaneously in a single pleiopluripotent cell, thereby reducing the time and cost associated with conventional methods of editing pleiopluripotent cells. Additionally, the methods described herein avoid the need for inducing double strand breaks, which increases accuracy of genome integration and reduces likelihood of off-target events. For example, using a beacon (e.g., an integration recognition site) incorporated at a particular genomic location to guide integration of the donor polynucleotide template increases integration efficiency of the donor polynucleotide template. Moreover, the methods described herein enable integration of larger donor polynucleotide template sequences compared to conventional methods which have payload capacity limitations. This is enabled, at least in part, by using single atgRNA (and optionally a nicking gRNA) or dual atgRNA to guide precise beacon placement (i.e., incorporation of one or more integration recognition sites) at desired loci. One application of these methods is the generation of pleiopluripotent cells that include one or more of (i) knockout of HLA Class I and/or Class II molecules, (ii) expression of self-molecules (e.g., one or more exogenous polypeptides capable of modulating an immune response), (iii) expression one or more controllable (e.g., inducible) suicide genes, (iv) expression of one or more adaptors (e.g., a tag), and (v) one or more landing pads (e.g., beacons) incorporated into the genome for integrating additional therapeutic agents (see FIG.2). Cells comprising one or more of these features provide a source of cells suitable for differentiation to a cell type of interest (e.g., without limitation, a hematopoietic cell, a neuronal cell, a cardiac cell, and a pancreatic cell) and use in cell therapy (e.g., allogeneic cell therapy). 6.1. Terminology [0234] Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by a person skilled in the art to which this disclosure belongs. As used herein, the following terms have the meanings ascribed to them below. [0235] “Gene editor” as used herein, is a protein that that can be used to perform gene editing, gene modification, gene insertion, gene deletion, or gene inversion. As used herein, the terms “gene editor polynucleotide” refers to a polynucleotide sequence encoding the gene editor polypeptide. Such an enzyme or enzyme fusion may contain DNA or RNA targetable nuclease protein (i.e., Cas protein, ADAR, or ADAT), wherein target specificity is mediated by a complexed nucleic acid (i.e., guide RNA). Such an enzyme or enzyme fusion may be a DNA/RNA targetable protein, wherein target specificity is mediated by internal, conjugated, fused, or linked amino acids, such as within TALENs, ZFNs, or meganucleases. The skilled person in the art would appreciate that the gene editor can demonstrate targeted nuclease activity, targeted binding with no nuclease activity, or targeted nickase activity (or cleavase activity). A gene editor comprising a targetable protein may be fused or linked to one or more proteins or protein fragment motifs. Gene editors may be fused, linked, complexed, operate in cis or trans to one or more integrase, recombinase, polymerase, telomerase, reverse transcriptase, or invertase. A gene editor can be a prime editor fusion protein or a gene writer fusion protein. [0236] “Prime editor fusion protein” as used herein, describes a protein that is used in prime editing. “Prime editor system” as used herein describes the components used in prime editing. Prime editing uses CRISPR enzyme that nicks or cuts only single strand of double stranded DNA, i.e., a nickase; the nickase can occur either naturally or by mutation or modification of a nuclease that makes double stranded cuts. Such an enzyme can be a catalytically impaired Cas9 endonuclease (a nickase). Such an enzyme can be a Casl2a/b, MAD7, or variant thereof. The nickase is fused to an engineered reverse transcriptase (RT). The nickase is programmed (directed) with an attachment site-containing guide RNA (or a prime-editing guide RNA (pegRNA)). The skilled person in the art would appreciate that the pegRNA both specifies the target site and encodes the desired edit. Described herein, are attachment site-containing guide RNA (atgRNA) that both specifies the target and encodes for the desired integrase target recognition site. The nickase may be programmed (directed) with an atgRNA. Advantageously the nickase is a catalytically-impaired Cas9 endonuclease, a Cas9 nickase, that is fused to the reverse transcriptase. During genetic editing, the Cas9 nickase part of the protein is guided to the DNA target site by the atgRNA (or pegRNA), whereby a nick or single stranded cut occurs. The reverse transcriptase domain then uses the atgRNA (or pegRNA) to template reverse transcription of the desired edit, directly polymerizing DNA onto the nicked target DNA strand. The edited DNA strand replaces the original DNA strand, creating a heteroduplex containing one edited strand and one unedited strand. Afterward, optionally, the prime editor (PE) guides resolution of the heteroduplex to favor copying the edit onto the unedited strand, completing the process (typically achieved with a nickase gRNA). Other enzymes that can be used to nick or cut only a single strand of double stranded DNA includes a cleavase (e.g., cleavase I enzyme). [0237] In some embodiments, an additional agent or agents may be added that improve the efficiency and outcome purity of the prime edit. In some embodiments, the agent may be chemical or biological and disrupt DNA mismatch repair (MMR) processes at or near the edit site (i.e., PE4 and PE5 and PEmax architecture by Chen et al. Cell, 184, 1-18, October 28, 2021; Chen et al. is incorporated herein by reference). In typical embodiments, the agent is a MMR-inhibiting protein. In certain embodiments, the MMR-inhibiting protein is dominant negative MMR protein. In certain embodiments, the dominant negative MMR protein is MLH1dn. In particular embodiments, the MMR-inhibiting agent is incorporated into the single nucleic acid construct design described herein. In some embodiments, the MMR-inhibiting agent is linked or fused to the prime editor protein fusion, which may or may not have a linked or fused integrase. In some embodiments, the MMR-inhibiting agent is linked or fused to the Gene Writer™ protein, which may or may not have a linked or fused integrase. [0238] The prime editor or gene editor system can be used to achieve DNA deletion and replacement. In some embodiments, the DNA deletion replacement is induced using a pair of atgRNAs (or pegRNA) that target opposite DNA strands, programming not only the sites that are nicked but also the outcome of the repair (i.e., PrimeDel by Choi et al. Nat. Biotechnology, October 14, 2021; Choi et al. is incorporated herein by reference and TwinPE by Anzalone et al., Nat. Biotech. 40: 731–740 (2022); Anzalone et al. is incorporated herein by reference). In some embodiments described herein, the DNA deletion is induced using a single atgRNA. In some embodiments, the DNA deletion and replacement is induced using a wild type Cas9 prime editor (PE-Cas9) system (i.e., PEDAR by Jiang et al. Nat. Biotechnology, October 14, 2021; Jiang et al. is incorporated herein by reference). In some embodiments, the DNA replacement is an integrase target recognition site or recombinase target recognition site. In certain embodiments, the constructs and methods described herein may be utilized to incorporate the pair of pegRNAs used in PrimeDel, TwinPE (WO2021226558, which is hereby incorporated by reference herein in its entirety), or PEDAR, the prime editor fusion protein or Gene Writer protein, optionally a nickase guide RNA (ngRNA), an integrase, a nucleic acid cargo, and optionally a recombinase into a single nucleic acid construct described herein. The integrase may be directly linked, for example by a peptide linker, to the prime editor fusion or gene writer protein. [0239] In some embodiments, the prime editors can refer to a retrovirus or lentivirus reverse transcriptase such as a Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase (RT) fused to a CRISPR enzyme nickase such as a Cas9 H840A nickase, a Cas9nickase. In some embodiments, the prime editors can refer to a retrovirus or lentivirus reverse transcriptase such as a Moloney Murine Leukemia Virus (M-MLV) reverse transcriptase (RT) fused to a cleavase. In some embodiments the RT can be fused at, near or to the C-terminus of a Cas9nickase, e.g., Cas9 H840A. Fusing the RT to the C-terminus region, e.g., to the C-terminus, of the Cas9 nickase may result in higher editing efficiency. Such a complex is called PEI. In some embodiments, the CRISPR enzyme nickase, e.g., Cas9(H840A), i.e., a Cas9nickase, can be linked to a non-M-MLV reverse transcriptase such as an AMV-RT or XRT (Cas9(H840A)-AMV-RT or XRT). In some embodiments, instead of the CRISPR enzyme nickase being a Cas9 (H840A), i.e., instead of being a Cas9 nickase, the CRISPR enzyme nickase instead can be a CRISPR enzyme that naturally is a nickase or cuts a single strand of double stranded DNA; for instance, the CRISPR enzyme nickase can be Casl2a/b. Alternatively, the CRISPR enzyme nickase can be another mutation of Cas9, such as Cas9(Dl0A). A CRISPR enzyme, such as a CRISPR enzyme nickase, such as Cas9 (wild type), Cas9(H840A), Cas9(Dl0A) or Cas 12a/b nickase can be fused in some embodiments to a pentamutant of M-MLV RT (D200N/ L603W/ T330P/ T306K/ W313F), whereby there can be up to about 45-fold higher efficiency, and this is called PE2. In some embodiments, the M-MLV RT comprise one or more of the mutations Y8H, P51L, S56A, S67R, E69K, Vl29P, L139P, Tl97A, H204R, V223H, T246E, N249D, E286R, Q2911, E302K, E302R, F309N, M320L, P330E, L435G, L435R, N454K, D524A, D524G, D524N, E562Q, D583N, H594Q, E607K, D653N, and L671P. Specific M-MLV RT mutations are shown in Table 1.

[0240] In some embodiments, the reverse transcriptase can also be a wild-type or modified transcription xenopolymerase (RTX), avian myeloblastosis virus reverse transcriptase (AMV RT), Feline Immunodeficiency Virus reverse transcriptase (FIV-RT), FeLV-RT (Feline leukemia virus reverse transcriptase), HIV-RT (Human Immunodeficiency Virus reverse transcriptase). In some embodiments, the reverse transcriptase can be a fusion of MMuLV to the Sto7d DNA binding domain (see Ionnidi et al.; https://doi.org/10.1101/2021.11.01.466786). The fusion of MMuLV to the Sto7d DNA binding domain sequence is given in Table 2.

[0241] PE3, PE3b, PE4, PE5, and/or PEmax, which a skilled person can incorporate into the gene editor polypeptide, involves nicking the non-edited strand, potentially causing the cell to remake that strand using the edited strand as the template to induce HR. The nicking of the non-edited strand can involve the use of a nicking guide RNA (ngRNA). [0242] The skilled person can readily incorporate into a gene editor polypeptide described herein a prime editing or CRISPR system. Examples of prime editors can be found in the following: WO2020/191153, WO2020/191171, WO2020/191233, WO2020/191234, WO2020/191239, WO2020/191241, WO2020/191242, WO2020/191243, WO2020/191245, WO2020/191246, WO2020/191248, WO2020/191249, each of which is incorporated by reference herein in its entirety.

Further, from the disclosures of the foregoing, the skilled person can incorporate the selected CRISPR enzyme, as part of the gene editor composition described herein. Additional gene editor polypeptides are as described in WO 2023/076898; WO 2023/015014; WO 2023/070062; WO2023288332; WO2023015318; WO2023004439; WO2023070110; WO2022256714; and WO2023283092, each of which are hereby incorporated by reference in their entireties. Additional gene editor polypeptides are as described in U.S. Patent Pub.2023/0059368, which is hereby incorporated by reference in its entirety. [0243] Prior to RT-mediated edit incorporation, the prime editor protein (1) site- specifically targets a genomic locus and (2) performs a catalytic cut or nick. These steps are typically performed by a CRISPR-Cas. However, in some embodiments the Cas protein may be substituted by other nucleic acid programmable DNA binding proteins (napDNAbp) such as zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), or meganucleases. In addition, to the extent the “targeting rules” of other napDNAbp are known or are newly determined, it becomes possible to use new napDNAbp, beyond Cas9, to site specifically target and modify genomic sites of interest. [0244] Similar to a prime editor protein, a Gene Writer can introduce novel DNA elements, such as an integration target site, into a DNA locus. A Gene Writer protein comprises: (A) a polypeptide or a nucleic acid encoding a polypeptide, wherein the polypeptide comprises (i) a reverse transcriptase domain, and either (x) an endonuclease domain that contains DNA binding functionality or (y) an endonuclease domain and separate DNA binding domain; and (B) a template RNA comprising (i) a sequence that binds the polypeptide and (ii) a heterologous insert sequence. Examples of such Gene Writer™ proteins and related systems can be found in US20200109398, which is incorporated by reference herein in its entirety. [0245] In some embodiments, the prime editor or Gene Writer protein fusion or prime editor protein linked or fused to an integrase is expressed as a split construct. In typical embodiments, the split construct in reconstituted in a cell. In some embodiments, the split construct can be fused or ligated via intein protein splicing. In some embodiments, the split construct can be reconstituted via protein-protein inter-molecular bonding and/or interactions. In some embodiments, the split construct can be reconstituted via chemical, biological, or environmental induced oligomerization. In some embodiments, the split construct can be reconstituted via nanobody binding ALFA-tagged proteins. In certain embodiments, the split construct can be adapted into one or more single nucleic acid polynucleotides. [0246] In some embodiments, an integrase or recombinase is directly linked or fused, for example by a peptide linker, which may be cleavable or non-cleavable, to the prime editor fusion protein (i.e., fused Cas9 nickase-reverse transcriptase) or Gene Writer protein. Suitable linkers, for example between the Cas9, RT, and integrase, may be selected from Table 3:

Type II CRISPR proteins [0247] The skilled person can incorporate a selected CRISPR enzyme, described below, as part of the prime editor fusion, as a component of the gene editor polypeptide described herein. Streptococcus pyogenes Cas9 (SpCas9), the most common enzyme used in genome-editing applications, is a large nuclease of 1368 amino acid residues. Advantages of SpCas9 include its short, 5′-NGG-3′ PAM and very high average editing efficiency. SpCas9 consists of two lobes: a recognition (REC) lobe and a nuclease (NUC) lobe. The REC lobe can be divided into three regions, a long a helix referred to as the bridge helix (residues 60–93), the REC1 (residues 94–179 and 308–713) domain, and the REC2 (residues 180–307) domain. The NUC lobe consists of the RuvC (residues 1–59, 718–769, and 909–1098), HNH (residues 775–908), and PAM-interacting (PI) (residues 1099–1368) domains. The negatively charged sgRNA:target DNA heteroduplex is accommodated in a positively charged groove at the interface between the REC and NUC lobes. In the NUC lobe, the RuvC domain is assembled from the three split RuvC motifs (RuvC I–III) and interfaces with the PI domain to form a positively charged surface that interacts with the 30 tail of the sgRNA. The HNH domain lies between the RuvC II–III motifs and forms only a few contacts with the rest of the protein. Structural aspects of SpCas9 are described by Nishimasu et al., Crystal Structure of Cas9 in Complex with Guide RNA and Target DNA, Cell 156, 935-949, February 27, 2014. [0248] REC lobe: The REC lobe includes the REC1 and REC2 domains. The REC2 domain does not contact the bound guide:target heteroduplex, indicating that truncation of REC lobe may be tolerated by SpCas9. Further, SpCas9 mutant lacking the REC2 domain (D175–307) retained ~50% of the wild-type Cas9 activity, indicating that the REC2 domain is not critical for DNA cleavage. In striking contrast, the deletion of either the repeat-interacting region (D97–150) or the anti-repeat-interacting region (D312–409) of the REC1 domain abolished the DNA cleavage activity, indicating that the recognition of the repeat:anti-repeat duplex by the REC1 domain is critical for the Cas9 function. [0249] PAM-Interacting domain: The NUC lobe contains the PAM-interacting (PI) domain that is positioned to recognize the PAM sequence on the noncomplementary DNA strand. The PI domain of SpCas9 is required for the recognition of 5’-NGG-3’ PAM, and deletion of the PI domain (Δ1099-1368) abolished the cleavage activity, indicating that the PI domain is critical for SpCas9 function and a major determinant for the PAM specificity. [0250] RuvC domain: The RuvC nucleases of SpCas9 have an RNase H fold and four catalytic residues, Asp10 (Ala), Glu762, His983, and Asp986, that are critical for the two-metal cleavage of the noncomplementary strand of the target DNA. In addition to the conserved RNase H fold, the Cas9 RuvC domain has other structural elements involved in interactions with the guide:target heteroduplex (an end-capping loop between α42 and α43) and the PI domain/stem loop 3 (β hairpin formed by β3 and β4). [0251] HNH domain: SpCas9 HNH nucleases have three catalytic residues, Asp839, His840, and Asn863 and cleave the complementary strand of the target DNA through a single-metal mechanism. [0252] sgRNA:DNA recognition: The sgRNA guide region is primarily recognized by the REC lobe. The backbone phosphate groups of the guide region (nucleotides 2, 4–6, and 13–20) interact with the REC1 domain (Arg165, Gly166, Arg403, Asn407, Lys510, Tyr515, and Arg661) and the bridge helix (Arg63, Arg66, Arg70, Arg71, Arg74, and Arg78). The 20-hydroxyl groups of G1, C15, U16, and G19 hydrogen bond with Val1009, Tyr450, Arg447/Ile448, and Thr404, respectively. [0253] A mutational analysis demonstrated that the R66A, R70A, and R74A mutations on the bridge helix markedly reduced the DNA cleavage activities, highlighting the functional significance of the recognition of the sgRNA ‘‘seed’’ region by the bridge helix. Although Arg78 and Arg165 also interact with the ‘‘seed’’ region, the R78A and R165A mutants showed only moderately decreased activities. These results are consistent with the fact that Arg66, Arg70, and Arg74 form multiple salt bridges with the sgRNA backbone, whereas Arg78 and Arg165 form a single salt bridge with the sgRNA backbone. Moreover, the alanine mutations of the repeat:anti- repeat duplex-interacting residues (Arg75 and Lys163) and the stemloop-1-interacting residue (Arg69) resulted in decreased DNA cleavage activity, confirming the functional importance of the recognition of the repeat:anti-repeat duplex and stem loop 1 by Cas9. [0254] RNA-guided DNA targeting: SpCas9 recognizes the guide:target heteroduplex in a sequence-independent manner. The backbone phosphate groups of the target DNA (nucleotides 1, 9–11, 13, and 20) interact with the REC1 (Asn497, Trp659, Arg661, and Gln695), RuvC (Gln926), and PI (Glu1108) domains. The C2’ atoms of the target DNA (nucleotides 5, 7, 8, 11, 19, and 20) form van der Waals interactions with the REC1 domain (Leu169, Tyr450, Met495, Met694, and His698) and the RuvC domain (Ala728). The terminal base pair of the guide:target heteroduplex (G1:C20’) is recognized by the RuvC domain via end-capping interactions; the sgRNA G1 and target DNA C20’ nucleobases interact with the Tyr1013 and Val1015 side chains, respectively, whereas the 20-hydroxyl and phosphate groups of sgRNA G1 interact with Val1009 and Gln926, respectively. [0255] Repeat:Anti-Repeat duplex recognition: The nucleobases of U23/A49 and A42/G43 hydrogen bond with the side chain of Arg1122 and the main-chain carbonyl group of Phe351, respectively. The nucleobase of the flipped U44 is sandwiched between Tyr325 and His328, with its N3 atom hydrogen bonded with Tyr325, whereas the nucleobase of the unpaired G43 stacks with Tyr359 and hydrogen bonds with Asp364. [0256] The nucleobases of G21 and U50 in the G21:U50 wobble pair stack with the terminal C20:G10 pair in the guide:target heteroduplex and Tyr72 on the bridge helix, respectively, with the U50 O4 atom hydrogen bonded with Arg75. Notably, A51 adopts the syn conformation and is oriented in the direction opposite to U50. The nucleobase of A51 is sandwiched between Phe1105 and U63, with its N1, N6, and N7 atoms hydrogen bonded with G62, Gly1103, and Phe1105, respectively. [0257] Stem-loop recognition: Stem loop 1 is primarily recognized by the REC lobe, together with the PI domain. The backbone phosphate groups of stem loop 1 (nucleotides 52, 53, and 59– 61) interact with the REC1 domain (Leu455, Ser460, Arg467, Thr472, and Ile473), the PI domain (Lys1123 and Lys1124), and the bridge helix (Arg70 and Arg74), with the 20-hydroxyl group of G58 hydrogen bonded with Leu455. A52 interacts with Phe1105 through a face-to-edge p-p stacking interaction, and the flipped U59 nucleobase hydrogen bonds with Asn77. [0258] The single-stranded linker and stem loops 2 and 3 are primarily recognized by the NUC lobe. The backbone phosphate groups of the linker (nucleotides 63–65 and 67) interact with the RuvC domain (Glu57, Lys742, and Lys1097), the PI domain (Thr1102), and the bridge helix (Arg69), with the 20-hydroxyl groups of U64 and A65 hydrogen bonded with Glu57 and His721, respectively. The C67 nucleobase forms two hydrogen bonds with Val1100. [0259] Stem loop 2 is recognized by Cas9 via the interactions between the NUC lobe and the non-Watson-Crick A68:G81 pair, which is formed by direct (between the A68 N6 and G81 O6 atoms) and water-mediated (between the A68 N1 and G81 N1 atoms) hydrogen-bonding interactions. The A68 and G81 nucleobases contact Ser1351 and Tyr1356, respectively, whereas the A68:G81 pair interacts with Thr1358 via a water-mediated hydrogen bond. The 20-hydroxyl group of A68 hydrogen bonds with His1349, whereas the G81 nucleobase hydrogen bonds with Lys33. [0260] Stem loop 3 interacts with the NUC lobe more extensively, as compared to stem loop 2. The backbone phosphate group of G92 interacts with the RuvC domain (Arg40 and Lys44), whereas the G89 and U90 nucleobases hydrogen bond with Gln1272 and Glu1225/Ala1227, respectively. The A88 and C91 nucleobases are recognized by Asn46 via multiple hydrogen- bonding interactions. [0261] Cas9 proteins smaller than SpCas9 allow more efficient packaging of nucleic acids encoding CRISPR systems, e.g., Cas9 and sgRNA into one rAAV (“all-in-one-AAV”) particle. In addition, efficient packaging of CRISPR systems can be achieved in other viral vector systems (i.e., lentiviral, hd-AAV, etc.) and non viral vector systems (i.e., lipid nanoparticle). Small Cas9 proteins can be advantageous for multidomain-Cas-nuclease-based systems for prime editing. Well characterized smaller Cas9 proteins include Staphylococcus aureus (SauCas9, 1053 amino acid residues) and Campylobacter jejuni (CjCas9, 984 amino residues). However, both recognize longer PAMs, 5′-NNGRRT-3′ for SauCas9 (R = A or G) and 5′-NNNNRYAC-3′ for CjCas9 (Y = C or T), which reduces the number of uniquely addressable target sites in the genome, in comparison to the NGG SpCas9 PAM. Among smaller Cas9s, Schmidt et al. identified Staphylococcus lugdunensis (Slu) Cas9 as having genome-editing activity and provided homology mapping to SpCas9 and SauCas9 to facilitate generation of nickases and inactive (“dead”) enzymes (Schmidt et al., 2021, Improved CRISPR genome editing using small highly active and specific engineered RNA-guided nucleases. Nat Commun 12, 4219. doi.org/10.1038/s41467-021- 24454-5) and engineered nucleases with higher cleavage activity by fragmenting and shuffling Cas9 DNAs. The small Cas9s and nickases are useful in the instant disclosure. [0262] Besides dead Cas9 and Cas9 nickase variants, the Cas9 proteins used herein may also include other “Cas9 variants” having at least about 70% identical, at least about 80% identical, at least about 90% identical, at least about 95% identical, at least about 96% identical, at least about 97% identical, at least about 98% identical, at least about 99% identical, at least about 99.5% identical, or at least about 99.9% identical to any reference Cas9 protein, including any wild type Cas9, or mutant Cas9 (e.g., a dead Cas9 or Cas9 nickase), or fragment Cas9, or circular permutant Cas9, or other variant of Cas9 disclosed herein or known in the art. In some embodiments, a Cas9 variant may have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 21, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 or more amino acid changes compared to a reference Cas9. In some embodiments, the Cas9 variant comprises a fragment of a reference Cas9 (e.g., a gRNA binding domain or a DNA-cleavage domain), such that the fragment is at least about 70% identical, at least about 80% identical, at least about 90% identical, at least about 95% identical, at least about 96% identical, at least about 97% identical, at least about 98% identical, at least about 99% identical, at least about 99.5% identical, or at least about 99.9% identical to the corresponding fragment of wild type Cas9. In some embodiments, the fragment is at least 30%, at least 35%, at least 40%, at least 45%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95% identical, at least 96%, at least 97%, at least 98%, at least 99%, or at least 99.5% of the amino acid length of a corresponding wild type Cas9. [0263] In some embodiments, the disclosure also may utilize Cas9 fragments that retain their functionality and that are fragments of any herein disclosed Cas9 protein. In some embodiments, the Cas9 fragment is at least 100 amino acids in length. In some embodiments, the fragment is at least 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250, or at least 1300 amino acids in length.

[0265] In some embodiments, prime editors utilized herein comprise CRISPR-Cas system enzymes other than type II enzymes. In certain embodiments, prime editors comprise type V or type VI CRISPR-Cas system enzymes. It will be appreciated that certain CRISPR enzymes exhibit promiscuous ssDNA cleavage activity and appropriate precautions should be considered. In certain embodiments, prime editors comprise a nickase or a dead CRISPR with nuclease function comprised in a different component. [0266] In various embodiments, the nucleic acid programmable DNA binding proteins utilized herein include, without limitation, Cas9 (e.g., dCas9 and nCas9), Cas12a (Cpf1), Cas12b1 (C2c1), Cas12b2, Cas12c (C2c3), Cas12d (CasY), Cas12e (CasX), C2c4, C2c5, C2c8, C2c9, C2c10, Cas13a (C2c2), Cas13b (C2c6), Cas13c (C2c7), Cas13d, and Argonaute. Cas-equivalents further include those described in Makarova et al., “C2c2 is a single-component programmable RNA- guided RNA-targeting CRISPR effector,” Science 2016; 353(6299) and Makarova et al., “Classification and Nomenclature of CRISPR-Cas Systems: Where from Here?,” The CRISPR Journal, Vol.1. No.5, 2018, the contents of which are incorporated herein by reference. One example of a nucleic acid programmable DNA-binding protein that has different PAM specificity than Cas9 is Clustered Regularly Interspaced Short Palindromic Repeats from Prevotella and Francisella 1 (i.e, Cas12a (Cpf1)). Similar to Cas9, Cas12a (Cpf1) is also a Class 2 CRISPR effector, but it is a member of type V subgroup of enzymes, rather than the type II subgroup. It has been shown that Cas12a (Cpf1) mediates robust DNA interference with features distinct from Cas9. Cas12a (Cpf1) is a single RNA-guided endonuclease lacking tracrRNA, and it utilizes a T- rich protospacer-adjacent motif (TTN, TTTN, or YTN). Moreover, Cpf1 cleaves DNA via a staggered DNA double-stranded break. Out of 16 Cpf1-family proteins, two enzymes from Acidaminococcus and Lachnospiraceae are shown to have efficient genome-editing activity in human cells. Cpf1 proteins are known in the art and have been described previously, for example Yamano et al., “Crystal structure of Cpf1 in complex with guide RNA and target DNA.” Cell (165) 2016, p.949-962; the entire contents of which is hereby incorporated by reference. 6.3. Type V CRISPR proteins [0267] In some embodiments, prime editors used herein comprise the type V CRISPR family includes Francisella novicida U112 Cpf1 (FnCpf1) also known as FnCas12a. FnCpf1 adopts a bilobed architecture with the two lobes connected by the wedge (WED) domain. The N-terminal REC lobe consists of two a-helical domains (REC1 and REC2) that have been shown to coordinate the crRNA-target DNA heteroduplex. The C-terminal NUC lobe consists of the C-terminal RuvC and Nuc domains involved in target cleavage, the arginine-rich bridge helix (BH), and the PAM- interacting (PI) domain. The repeat-derived segment of the crRNA forms a pseudoknot stabilized by intra-molecular base-pairing and hydrogen-bonding interactions. The pseudoknot is coordinated by residues from the WED, RuvC, and REC2 domains, as well as by two hydrated magnesium cations. Notably, nucleotides 1–5 of the crRNA are ordered in the central cavity of FnCas12a and adopt an A-form-like helical conformation. Conformational ordering of the seed sequence is facilitated by multiple interactions between the ribose and phosphate moieties of the crRNA backbone and FnCpf1 residues in the WED and REC1 domains. These include residues Thr16, Lys595, His804, and His881 from the WED domain and residues Tyr47, Lys51, Phe182, and Arg186 from the REC1 domain. The structure of the FnCas12a-crRNA complex further reveals that the bases of the seed sequence are solvent exposed and poised for hybridization with target DNA. Structural aspects of FnCpf1 are described by Swarts et al., Structural Basis for Guide RNA Processing and Seed-Dependent DNA Targeting by CRISPR-Cas12a, Molecular Cell 66, 221-233, April 20, 2017. [0268] Pre-crRNA processing: Essential residues for crRNA processing include His843, Lys852, and Lys869. Structural observations are consistent with an acid-base catalytic mechanism in which Lys869 acts as the general base catalyst to deprotonate the attacking 2’-hydroxyl group of U(-19), while His843 acts as a general acid to protonate the 5’-oxygen leaving group of A(-18). In turn, the side chain of Lys852 is involved in charge stabilization of the transition state. Collectively, these interactions facilitate the intra-molecular attack of the 20-hydroxyl group of U(-19) on the scissile phosphate and promote the formation of the 2’,3’-cyclic phosphate product. [0269] R-loop formation: The crRNA-target DNA strand heteroduplex is enclosed in the central cavity formed by the REC and NUC lobes and interacts extensively with the REC1 and REC2 domains. The PAM-containing DNA duplex comprises target strand nucleotides dT0–dT8 and non-target strand nucleotides dA(8)*–dA0* and is contacted by the PI, WED, and REC1 domains. The 5’-TTN-3’ PAM is recognized in FnCas12a by a mechanism combining the shape- specific recognition of a narrowed minor groove, with base-specific recognition of the PAM bases by two invariant residues, Lys671 and Lys613. Directly downstream of the PAM, the duplex of the target DNA is disrupted by the side chain of residue Lys667, which is inserted between the DNA strands and forms a cation-π stacking interaction with the dA0–dT0* base pair. The phosphate group linking target strand residues dT(-1) and dT0 is coordinated by hydrogen-bonding interactions with the side chain of Lys823 and the backbone amide of Gly826. Target strand residue dT(-1) bends away from residue T0, allowing the target strand to interact with the seed sequence of the crRNA. The non-target strand nucleotides dT1*–dT5* interact with the Arg692- Ser702 loop in FnCas12a through hydrogen-bonding and ionic interactions between backbone phosphate groups and side chains of Arg692, Asn700, Ser702, and Gln704, as well as main-chain amide groups of Lys699, Asn700, and Ser702. Alanine substitution of Q704 or replacement of residues Thr698–Ser702 in FnCas12a with the sequence Ala-Gly3 (SEQ ID NO: 115) substantially reduced DNA cleavage activity, suggesting that these residues contribute to R-loop formation by stabilizing the displaced conformation of the nontarget DNA strand. [0270] In the FnCas12a R-loop complex, the crRNA-target strand heteroduplex is terminated by a stacking interaction with a conserved aromatic residue (Tyr410). This prevents base pairing between the crRNA and the target strand beyond nucleotides U20 and dA(-20), respectively. Beyond this point, the target DNA strand nucleotides re-engage the non-target DNA strand, forming a PAM-distal DNA duplex comprising nucleotides dC(-21)–dA(-27) and dG21*–dT27*, respectively. The duplex is confined between the REC2 and Nuc domains at the end of the central channel formed by the REC and NUC lobes. [0271] Target DNA cleavage: FnCpf1 can independently accommodate both the target and non-target DNA strands in the catalytic pocket of the RuvC domain. The RuvC active site contains three catalytic residues (D917, E1006, and D1255). Structural observations suggest that both the target and non-target DNA strands are cleaved by the same catalytic mechanism in a single active site in Cpf1/Cas12a enzymes. [0272] Another type V CRISPR is AsCpf1 from Acidaminococcus sp BV3L6 (Yamano et al., Crystal structure of Cpf1 in complex with guide RNA and target DNA, Cell 165, 949-962, May 5, 2016) [0273] In certain embodiments, the nuclease comprises a Cas12f effector. Small CRISPR- associated effector proteins belonging to the type V-F subtype have been identified through the mining of sequence databases and members classified into Cas12f1 (Cas14a and type V-U3), Cas12f2 (Cas14b) and Cas12f3 (Cas14c, type V-U2 and U4). (See, e.g., Karvelis et al., PAM recognition by miniature CRISPR–Cas12f nucleases triggers programmable double-stranded DNA target cleavage. Nucleic Acids Research, 21 May 2020, 48(9), 5016–23 doi.org/10.1093/nar/gkaa208). Xu et al. described development of a 529 amino acid Cas12f-based system for mammalian genome engineering through multiple rounds of iterative protein engineering and screening. (Xu, X. et al., Engineered Miniature CRISPR-Cas System for Mammalian Genome Regulation and Editing. Molecular Cell, October 21, 2021, 81(20): 4333-45, doi.org/10.1016/j.molcel.2021.08.008).

6.4. Protospacer Adjacent Motif [0275] As used herein, the term “protospacer adjacent sequence” or “protospacer adjacent motif” or “PAM” refers to an approximately 2-6 base pair DNA sequence (or a 2-, 3-, 4-, 5-, 6-, 7-, 8-, 9-, 10-, 11-, 12-long nucleotide sequence) that is an important targeting component of a Cas9 nuclease. Typically, the PAM sequence is on either strand, and is downstream in the 5' to 3' direction of Cas9 cut site. The canonical PAM sequence (i.e., the PAM sequence that is associated with the Cas9 nuclease of Streptococcus pyogenes or SpCas9) is 5'-NGG-3' wherein “N” is any nucleobase followed by two guanine (“G”) nucleobases. Different PAM sequences can be associated with different Cas9 nucleases or equivalent proteins from different organisms. In addition, any given Cas9 nuclease may be modified to alter the PAM specificity of the nuclease such that the nuclease recognizes alternative PAM sequence. [0276] For example, with reference to the canonical SpCas9 amino acid sequence, the PAM specificity can be modified by introducing one or more mutations, including (a) D1135V, R1335Q, and T1337R “the VQR variant”, which alters the PAM specificity to NGAN or NGNG, (b) D1135E, R1335Q, and T1337R “the EQR variant”, which alters the PAM specificity to NGAG, and (c) D1135V, G1218R, R1335E, and T1337R “the VRER variant”, which alters the PAM specificity to NGCG. In addition, the D1135E variant of canonical SpCas9 still recognizes NGG, but it is more selective compared to the wild type SpCas9 protein. [0277] It will also be appreciated that Cas9 enzymes from different bacterial species (i.e., Cas9 orthologs) can have varying PAM specificities and in some embodiments are therefore chosen based on the desired PAM recognition. For example, Cas9 from Staphylococcus aureus (SaCas9) recognizes NGRRT or NGRRN. In addition, Cas9 from Neisseria meningitis (NmCas) recognizes NNNNGATT. In another example, Cas9 from Streptococcus thermophilis (StCas9) recognizes NNAGAAW. In still another example, Cas9 from Treponema denticola (TdCas) recognizes NAAAAC. These examples are not meant to be limiting. It will be further appreciated that non- SpCas9s bind a variety of PAM sequences, which makes them useful to expand the range of sequences that can be targeted according to the invention. Furthermore, non-SpCas9s may have other characteristics that make them more useful than SpCas9. For example, Cas9 from Staphylococcus aureus (SaCas9) is about 1 kilobase smaller than SpCas9, so it can be packaged into adeno-associated virus (AAV). Further reference may be made to Shah et al., “Protospacer recognition motifs: mixed identities and functional diversity,” RNA Biology, 10(5): 891-899 (which is incorporated herein by reference). Gasiunas used cell-free biochemical screens to identify protospacer adjacent motif (PAM) and guide RNA requirements of 79 Cas9 proteins. (Gasiunas et al., A catalogue of biochemically diverse CRISPR-Cas9 orthologs, Nature Communications 11:5512 doi.org/10.1038/s41467-020-19344-1) The authors described 7 classes of gRNA and 50 different PAM requirement. [0278] Oh, Y. et al. describe linking reverse transcriptase to a Francisella novicida Cas9 [FnCas9(H969A)] nickase module. (Oh, Y. et al., Expansion of the prime editing modality with Cas9 from Francisella novicida, bioRxiv 2021.05.25.445577; doi.org/10.1101/2021.05.25.445577). By increasing the distance to the PAM, the FnCas9(H969A) nickase module expands the region of a reverse transcription template (RTT) following the primer binding site. 6.5. Gene Editor Polypeptides [0279] “Prime editor fusion protein” describes a protein that is used in prime editing. Prime editing uses CRISPR enzyme that nicks or cuts only single strand of double stranded DNA, i.e., a nickase; and a nickase can occur either naturally or by mutation or modification of a nuclease that makes double stranded cuts. Such an enzyme can be a catalytically-impaired Cas9 endonuclease (a nickase). Such an enzyme can be a Casl2a/b, MAD7, or variant thereof. The nickase is fused to an engineered reverse transcriptase (RT). The nickase is programmed (directed) with a attachment site-containing guide RNA. The skilled person in the art would appreciate that the atgRNA both specifies the target site and encodes the desired edit. Advantageously the nickase is a catalytically-impaired Cas9 endonuclease, a Cas9 nickase, that is fused to the reverse transcriptase. During genetic editing, the Cas9 nickase part of the protein is guided to the DNA target site by the pegRNA, whereby a nick or single stranded cut occurs. The reverse transcriptase domain then uses the pegRNA to template reverse transcription of the desired edit, directly polymerizing DNA onto the nicked target DNA strand. The edited DNA strand replaces the original DNA strand, creating a heteroduplex containing one edited strand and one unedited strand. Afterward, optionally, the prime editor (PE) guides resolution of the heteroduplex to favor copying the edit onto the unedited strand, completing the process (typically achieved with a nickase gRNA). [0280] As used herein, “PE1” refers to a PE complex comprising a fusion protein comprising Cas9(H840A) and a wild type MMLV RT having the following N-terminus to C-terminus structure: [NLS]-[Cas9(H840A)]- [linker]-[MMLV_RT(wt)] + a desired atgRNA. In various embodiments, the prime editors disclosed herein is comprised of PE1. [0281] As used herein, “PE2” refers to a PE complex comprising a fusion protein comprising Cas9(H840A) and a variant MMLV RT having the following N-terminus to C-terminus structure: [NLS]-[Cas9(H840A)]- [linker]-[MMLV_RT(D200N)(T330P)(L603W)(T306K)(W313F)] + a desired PEgRNA. In various embodiments, the prime editors disclosed herein is comprised of PE2. [0282] In various embodiments, the prime editors disclosed herein is comprised of PE2 and co-expression of MMR protein MLH1dn, that is PE4. [0283] As used herein, “PE3” refers to PE2 plus a second-strand nicking guide RNA that complexes with the PE2 and introduces a nick in the non-edited DNA strand. The induction of the second nick increases the chances of the unedited strand, rather than the edited strand, to be repaired. In various embodiments, the prime editors disclosed herein is comprised of PE3. [0284] In various embodiments, the prime editors disclosed herein is comprised of PE3 and co-expression of MMR protein MLH1dn, that is PE5. [0285] As used herein, “PE3b” refers to PE3 but wherein the second-strand nicking guide RNA is designed for temporal control such that the second strand nick is not introduced until after the installation of the desired edit. This is achieved by designing a gRNA with a spacer sequence with mismatches to the unedited original allele that matches only the edited strand. Using this strategy, mismatches between the protospacer and the unedited allele should disfavor nicking by the sgRNA until after the editing event on the PAM strand takes place. 6.6. Guides for Prime Editing [0286] Anzalone et al., 2019 (Nature 576:149) describes prime editing and a prime editing complex using a type II CRISPR and can be used herein. A prime editing complex consists of a type II CRISPR PE protein containing an RNA-guided DNA-nicking domain fused to a reverse transcriptase (RT) domain and complexed with a pegRNA. The pegRNA comprises (5’ to 3’) a spacer that is complementary to the target sequence of a genomic DNA, a nickase (e.g. Cas9) binding site, a reverse transcriptase template including editing positions, and primer binding site (PBS). The PE–pegRNA complex binds the target DNA and the CRISPR protein nicks the PAM- containing strand. The resulting 3′ end of the nicked target hybridizes to the primer-binding site (PBS) of the pegRNA, then primes reverse transcription of new DNA containing the desired edit using the RT template of the pegRNA. The overall structure of the pegRNA is like that of a typical type II sgRNA with a reverse transcriptase template/primer binding site appended to the 3’ end. The structure leaves the PBS at the 3’ end of the pegRNA free to bind to the nicked strand complementary to the target which forms the primer for reverse transcription. [0287] Guide RNAs of CRISPRs differ in overall structure. For example, while the spacer of a type II gRNA is located at the 5’ end, the spacer of a type V gRNA is located towards the 3’ end, with the CRISPR protein (e.g. Cas12a) binding region located toward the 5’ end. Accordingly, the regions of a type V pegRNA are rearranged compared to a type II pegRNA. The overall structure of the pegRNA is like that of a typical type II sgRNA with a reverse transcriptase template/primer binding site appended to the 3’ end. The pegRNA comprises (5’ to 3’) a CRISPR protein-binding region, a spacer which is complementary to the target sequence of a genomic DNA, a reverse transcriptase template including editing positions, and primer binding site (PBS). [0288] In typical embodiments, the guide RNA or guide RNA complex is capable of binding a DNA binding nickase selected from the group consisting of: Cas9-D10A, Cas9-H840A, Cas12a/b/c/d/e nickase, CasX nickase, SaCas9 nickase, and CasY nickase. In certain embodiments, the nickase is linked or fused to one or more of a reverse transcriptase. In certain embodiments, the nickase is linked or fused to one or more of a reverse transcriptase and integrase. In certain embodiments, the nickase is linked or fused to one or more of an integrase. 6.7. Attachment Site-Containing Guide RNA (atgRNA) [0289] As used herein, the term "attachment site-containing guide RNA" (atgRNA) and the like refer to an extended single guide RNA (sgRNA) comprising a primer binding site (PBS), a reverse transcriptase (RT) template sequence, and wherein the RT template encodes for an integration recognition site or a recombinase recognition site that can be recognized by a recombinase, integrase, or transposase. In some embodiments, the RT template comprises a clamp sequence and an integration recognition site. As referred to herein an atgRNA may be referred to as a guide RNA. An integration recognition site or recombinase target recognition site incorporated into the pegRNA is referred to as an attachment site containing guide RNA (atgRNA). [0290] As used herein, the term “cognate integration recognition site” or “integration cognate” or “cognate pair” refers to a first integration recognition site (e.g., any of the integration recognition sites described herein) and a second integration recognition site (e.g., any of the integration recognition sites described herein) that can be recombined. Recombination between a first integration recognition site (e.g., any of the integration recognition sites described herein) and a second recognition site (e.g., any of the integration recognition sites described herein) is mediated by functional symmetry between the two integration recognition sites and the central dinucleotide of each of the two integration recognition sites. In some cases, a first integration recognition site (e.g., any of the integration recognition sites described herein) that can be recombined with a second integration recognition site (e.g., any of the integration recognition sites described herein) are referred to as a “cognate pair.” A non-limiting example of a cognate pair include an attB site and an attP site, whereby a serine integrase mediates recombination between the attB site and the attP site. FIGs.1A-1E show optimization of the integration recognition site. [0291] In typical embodiments, an atgRNA comprises a reverse transcriptase template that encodes, partially or in its entirety, an integration recognition site (also referred to as an integration target recognition site) or a recombinase recognition site (also referred to as a recombinase target recognition site). The integration target recognition site, which is to be placed at a desired location in the genome or intracellular nucleic acid, is referred to as a “beacon,” a “beacon” site or an “attachment site” or an “integration recognition site” or a “landing pad” or “landing site.” An integration target recognition site or recombinase target recognition site incorporated into the pegRNA is referred to as an attachment site containing guide RNA (atgRNA). [0292] In typical embodiments, an atgRNA comprises a reverse transcriptase template that encodes, partially or in entirety, for an integration target recognition site or recombinase target recognition site. The integration target recognition site, which is to be place at a desired location in the genome, is referred to as a “beacon site” or an “attachment site” or a “landing pad” or “landing site.” [0293] During genome editing, the primer binding site allows the 3' end of the nicked DNA strand to hybridize to the atgRNA, while the RT template serves as a template for the synthesis of edited genetic information. The atgRNA is capable for instance, without limitation, of (i) identifying the target nucleotide sequence to be edited and (ii) encoding new genetic information that replaces (or in some cases adds) the targeted sequence. In some embodiments, the atgRNA is capable of (i) identifying the target nucleotide sequence to be edited and (ii) encoding an integration site that replaces (or inserts/deletes within) the targeted sequences. [0294] In some embodiments, where the system contains a first atgRNA and a second atgRNA (see FIG.5), the first atgRNA and the second atgRNA are an at least first pair of atgRNAs, where the at least first pair of atgRNAs have domains that are capable of guiding the gene editor polypeptide or prime editor fusion protein to a target sequence, the first atgRNA further includes a first RT template that comprises at least a portion of the first integration recognition site; and the second atgRNA further includes a second RT template that comprises at least a portion of the first integration recognition site, and the first atgRNA and the second atgRNAs collectively encode the entirety of the first integration recognition site. [0295] In some embodiments, the first atgRNA’s reverse transcriptase template encodes for a first single-stranded DNA sequence (i.e., a first DNA flap) that contains a complementary region to a second single-stranded DNA sequence (i.e., a second DNA flap) encoded by a second atgRNA comprising a second reverse transcriptase template. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 5 consecutive bases of an integrase target recognition site. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 10 consecutive bases of an integrase target recognition site. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 20 consecutive bases of an integrase target recognition site. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 30 consecutive bases of an integrase target recognition site. Use of two guide RNAs that are (or encode DNA that is) partially complementarity to each other and comprised of consecutive bases of an integrase target recognition site are referred to as dual, paired, annealing, complementary, or twin attachment site-containing guide RNAs (atgRNAs). In certain embodiments, use of two guide RNAs that are (or encode DNA that is) full complementarity to each other and comprised of consecutive bases of an integrase target recognition site are referred to as dual, paired, annealing, complementary, or twin attachment site- containing guide RNAs (atgRNAs). [0296] As shown in FIGs. 1A-1E, AttP variants (SEQ ID NOS: 394 and 540-542, respectively, in order of appearance) can be optimized. [0297] Table 9 includes atgRNAs, sgRNAs and nicking guides that can be used herein. Spacers are labeled in capital font (SPACER), RT regions in bold capital (RT REGION), AttB sites in bold lower case (attb site), and PBS in capital italics (PBS).

6.8. Integrases/Recombinases and Integration/Recombination Sites [0298] In typical embodiments, a gene editor polypeptide described herein contains an integrase or recombinase. In some embodiments, the integrase is delivered as a protein or the integrase is encoded in a delivered polynucleotide. In some embodiments, the integration enzyme is selected from the group consisting of Dre, Vika, Bxb1, ϕC31, RDF, ϕBTl, R1, R2, R3, R4, R5, TP901-1, A118, ϕFCl, ϕC1, MR11, TG1, ϕ370.l, Wβ, BL3, SPBc, K38, Peaches, Veracruz, Rebeuca, Theia, Benedict, KSSJEB, PattyP, Doom, Scowl, Lockley, Switzer, Bob3, Troube, Abrogate, Anglerfish, Sarfire, SkiPole, ConceptII, Museum, Severus, Airmid, Benedict, Hinder, ICleared, Sheen, Mundrea, BxZ2, ϕRV, retrotransposases encoded by a Tc1/mariner family member including but not limited to retrotransposases encoded by LI, Tol2, Tel, Tc3, Himar 1 (isolated from the horn fly, Haematobia irritans), Mos1 (Mosaic element of Drosophila mauritiana), and Minos, and any mutants thereof. As can be used herein, Xu et al describes methods for evaluating integrase activity in E. coli and mammalian cells and confirmed at least R4, φC31, φBT1, Bxb1, SPBc, TP901-1 and Wβ integrases to be active on substrates integrated into the genome of HT1080 cells (Xu et al., 2013, Accuracy and efficiency define Bxb1 integrase as the best of fifteen candidate serine recombinases for the integration of DNA into the human genome. BMC Biotechnol.2013 Oct 20;13:87. doi: 10.1186/1472-6750-13-87). Durrant describes new large serine recombinases (LSRs) divided into three classes distinguished from one another by efficiency and specificity, including landing pad LSRs which outperform wild-type Bxb1 in episomal and chromosomal integration efficiency, LSRs that achieve both efficient and site- specific integration without a landing pad, and multi-targeting LSRs with minimal site-specificity. Additionally, embodiments can include any serine recombinase such as BceINT, SSCINT, SACINT, and INT10 (see Ionnidi et al., 2021; Drag-and-drop genome insertion without DNA cleavage with CRISPR directed integrases. bioRxiv 2021.11.01.466786, doi.org/10.1101/2021.11.01.466786). In some embodiments, the integration site can be selected from an attB site, an attP site, an attL site, an attR site, a lox71 site a Vox site, or a FRT site. [0299] It will be appreciated that desired activity of integrases, transposases and the like can depend on nuclear localization. In certain embodiments, prokaryotic enzymes are adapted to modulate nuclear localization. In certain embodiments, eukaryotic or vertebrate enzymes are adapted to modulate nuclear localization. In certain embodiments, the disclosure provides fusion or hybrid proteins. Such modulation can comprise addition or removal of one or more nuclear localization signal (NLS) and/or addition or removal of one or more nuclear export signal (NES). Xu et al compared derivatives of fourteen serine integrases that either possess or lack a nuclear localization signal (NLS) to conclude that certain integrases benefit from addition of an NLS whereas others are transported efficiently without addition, and a major determinant of activity in yeast and vertebrate cells is avoidance of toxicity. (Xu et al., 2016, Comparison and optimization of ten phage encoded serine integrases for genome engineering in Saccharomyces cerevisiae. BMC Biotechnol. 2016 Feb 9; 16:13. doi: 10.1186/s12896-016-0241-5). Ramakrishnan et al. systematically studied the effect of different NES mutants developed from mariner-like elements (MLEs) on transposase localization and activity and concluded that nuclear export provides a means of controlling transposition activity and maintaining genome integrity. (Ramakrishnan et al. Nuclear export signal (NES) of transposases affects the transposition activity of mariner-like elements Ppmar1 and Ppmar2 of moso bamboo. Mob DNA. 2019 Aug 19;10:35. doi:10.1186/s13100-019-0179-y). The methods and constructs are used to modulate nuclear localization of system components of the invention. In typical embodiments, the integrase used herein is selected from Table 10.

[0300] Sequences of insertion sites (i.e., recognition target sites) suitable for use in embodiments of the disclosure are presented below.

[0301] In certain embodiments, the one or more integration recognition sites is specific for a serine integrase other than BxB1. [0302] In some embodiments, the integration enzyme is selected from one of the about 27,000 Serine integrases described in International Patent Publication No. WO 2023/070031A2, which is hereby incorporated by reference in its entirety. 6.9. Split Gene Editor Guide RNA Compositions [0303] The present disclosure contemplates a split guide RNA comprised of two or more polynucleotides that are capable of forming a guide RNA complex (see Liu et al; doi: 10.1038/s41587-022-01255-9 the entirety of which is incorporated by reference herein). In some embodiments, the guide RNA may be a guide RNA complex, wherein the guide RNA complex is comprised of at least two polynucleotide components. In certain embodiments, the guide RNA complex is comprised of a first polynucleotide component and a second polynucleotide component. In certain embodiments, the first polynucleotide component comprises a spacer complementary to a target first genomic site and a scaffold capable of binding to a DNA binding nickase, and wherein the second polynucleotide component comprises a reverse transcriptase template comprised of at least an integrase target recognition site, a primer binding site and a RNA- protein recruitment domain. In some embodiments, the RNA-protein recruitment domain is a MS2 hairpin. [0304] In some embodiments, at least one of the first polynucleotide component and the second polynucleotide component are circularized. In some embodiments, circularization is mediated by a ribozyme or ligase. In some embodiments, circularization is mediated by covalently or non-covalently linking the 5’ and 3’ termini. [0305] In certain embodiments, the guide RNA or the guide RNA complex further comprises one or more of an RNA-protein recruitment domain, RNA-RNA recruitment domain, a transcriptional termination signal, a reverse transcription termination signal, an RNA ribozyme, or a chemical linker. [0306] In typical embodiments, one or more guide RNA complex is comprised in one or more RNA polynucleotides or DNA polynucleotides. 6.10. Guide RNA Compositions for Dual Guide RNA Systems [0307] In some embodiments, the guide RNA or the guide RNA complex reverse transcriptase template encodes for a first single-stranded DNA sequence (i.e., a first DNA flap) that contains a complementary region to a second single-stranded DNA sequence (i.e., a second DNA flap) encoded by a second guide RNA comprised of a reverse transcriptase template. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 5 consecutive bases of an integrase target recognition site. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 10 consecutive bases of an integrase target recognition site. In certain embodiments, the complementary region between the first and second single- stranded DNA sequences is comprised of more than 20 consecutive bases of an integrase target recognition site. In certain embodiments, the complementary region between the first and second single-stranded DNA sequences is comprised of more than 30 consecutive bases of an integrase target recognition site. Use of two guide RNAs that are (or encode DNA that is) partially complementarity to each other and comprised of consecutive bases of an integrase target recognition site are referred to as dual, paired, annealing, complementary, or twin attachment site- containing guide RNAs (atgRNAs). In certain embodiments, use of two guide RNAs that are (or encode DNA that is) full complementarity to each other and comprised of consecutive bases of an integrase target recognition site are referred to as dual, paired, annealing, complementary, or twin attachment site-containing guide RNAs (atgRNAs). [0308] In some embodiments, the integrase target recognition site is an Bxb1 attB or attP sequence. In some embodiments, the att-site central dinucleotide is not GT or CA. [0309] In typical embodiments, one or more guide RNA or the guide RNA complex is comprised in one or more RNA polynucleotides or DNA polynucleotides. [0310] In typical embodiments, the one or more guide RNA complex is a split guide RNA complex or split guide RNA system. In typical embodiments, the one or more guide RNA complex is a split atgRNA complex or split atgRNA system. [0311] A non-limiting example of a dual gRNA (i.e., dual atgRNA system) is as described in FIG.5. 6.11. Programmable Gene Insertion within a Pleiopluripotent Cell Genome [0312] Described herein is a method of editing a pleiopluripotent cell genome. In typical embodiments, the pleiopluripotent cells are edited using, at least in part, the information provided in FIGs.1-5. In some embodiments, editing the pleiopluripotent cell genome results in a cell that, following differentiation and transplantation into a subject, is capable of evading a subject’s immune system (e.g., encoding for one or more exogenous polypeptides that modulate immune response) but safeguarded from runaway expansion (e.g., inducible suicide genes) (see, e.g., FIG. 2). In some embodiments, the methods described herein are designed so that beacons (and ultimately the donor polynucleotide templates) are targeted to genomic loci with the aim of reducing expression (e.g., knocking out) of the gene associated with the particular genomic locus being targeted while also serving as a genomic locus suitable for expression of the aforementioned transgenes (e.g., exogenous polypeptides capable of modulating an immune response, inducible suicide genes, or a combination thereof). The pleiopluripotent cell genome can be further modified to include additional integration recognition sites (i.e., landing pads and beacons) incorporated into the genome for integrating additional polynucleotides encoding therapeutic agents. Example 10 provides a non-limiting exemplary method for generating pleiopluripotent stem cells having a beacon (integration recognition site) in each of the B2M, CIITA, TRAC, and AAVS1 loci. The pleiopluripotent stem cells can then be used for programmable gene insertion. In some cases, this achieved using multiplex programmable gene insertion, for example, where a different donor polynucleotide template is inserted into each beacon site-specifically placed into the aforementioned loci (see, e.g., Example 11). The resulting genetically modified pleiopluripotent cells can be differentiated to a non-pleiopluripotent cell (e.g., a hematopoietic cell, a neuronal cell, a cardiac cell, or a pancreatic cell) and used as a source of material for allogeneic cell therapy. [0313] In a typical embodiment, a method of generating pleiopluripotent cells includes site- specifically incorporating at least a first integration recognition site into the genome of a pleiopluripotent cell. [0314] In some embodiments, site-specifically incorporating the at least first integration recognition site is effected by introducing into the pleiopluripotent stem cell: (i) a gene editor protein or a polynucleotide encoding a gene editor protein or a prime editor fusion protein or a polynucleotide encoding a prime editor fusion protein; (ii) at least a first pair of guide RNAs, wherein the first paired guide RNAs have domains that are capable of guiding the gene editor protein or prime editor fusion protein to nick the pleiopluripotent stem cell genome at sites respectively flanking the specific incorporation site, and at least one of the two paired guide RNAs is an atgRNA that further includes a reverse transcriptase (RT) template that comprises at least a portion of the first integration recognition site, and the atgRNAs collectively encode the entirety of the first integration recognition site, whereby the first integration recognition site is site- specifically incorporated into the genome of the pleiopluripotent stem cell. [0315] In some embodiments, the at least first pair of guide RNAs comprise: (i) the first of the two paired guide RNAs is a first atgRNA that further includes a first RT template that comprises at least a portion of the first integration recognition site; and (ii) a second of the two paired guide RNAs is a second atgRNA that further includes a second RT template that comprises at least a portion of the first integration recognition site, wherein the first atgRNA and the second atgRNAs collectively encode the entirety of the first integration recognition site. [0316] In some embodiments, the at least first pair of guide RNAs comprise: (i) the first of the two paired guide RNAs is an atgRNA that further includes an RT template that comprises at least a portion of the first integration recognition site, wherein the atgRNA encodes the entirety of the first integration recognition site; and (ii) a second of the two paired guide RNAs is a nicking gRNA. [0317] In some embodiments, the methods include incorporating a plurality of integration recognition sites into the genome of a pleiopluripotent cell. In some embodiments, the method includes incorporating two integration recognition sites, three integration recognition sites, four integration recognition sites, five integration recognition sites, six integration recognition sites, seven integration recognition sites, eight integration recognition sites, nine integration recognition sites, or ten or more integration recognition sites into the genome of a pleiopluripotent cell. In some embodiments, each of the additional integration recognition sites (e.g., second, third, fourth, fifth, sixth, seventh, eighth, ninth, or tenth or more) are an orthogonal pair with an integration recognition site in one or more additional donor polynucleotides. [0318] In another embodiment, a method of generating pleiopluripotent cells includes (a) site- specifically incorporating at least a first integration recognition site into the genome of a pleiopluripotent cell, wherein site-specifically incorporating the at least first integration recognition site is effected by introducing into the pleiopluripotent stem cell: (i) a gene editor protein or a polynucleotide encoding a gene editor protein or a prime editor fusion protein or a polynucleotide encoding a prime editor fusion protein; (ii) at least a first pair of guide RNAs, wherein the first paired guide RNAs have domains that are capable of guiding the gene editor protein or prime editor fusion protein to nick the pleiopluripotent stem cell genome at sites respectively flanking the specific incorporation site, and at least one of the two paired guide RNAs is an atgRNA that further includes a reverse transcriptase (RT) template that comprises at least a portion of the first integration recognition site, and the atgRNAs collectively encode the entirety of the first integration recognition site, whereby the first integration recognition site is site- specifically incorporated into the genome of the pleiopluripotent stem cell; and (b) integrating at least a first donor polynucleotide template into the pleiopluripotent cell genome at the first incorporated integration recognition site, by introducing into the cell: (i) the first donor polynucleotide template, wherein the first donor polynucleotide template is comprised of one or more orthogonal integration recognition sites, and (ii) an integrase, whereby the donor polynucleotide is integrated into the pleiopluripotent stem cell at the at least one incorporated integration recognition site by the integrase; thereby producing a second generation pleiopluripotent cell. In some embodiments, incorporation of the integration recognition site into the pleiopluripotent cell genome is performed concurrently with integration of the donor polynucleotide template into the pleiopluripotent cell genome. [0319] In some embodiments, an at least first integration recognition site is incorporated into the genome of the pleiopluripotent cell using a homology directed repair, homology-independent target insertion (HITI), retrotransposon-mediated integration, viral vector-mediated integration (e.g., lentivirus), transposon-mediated integration (e.g., sleeping beauty), and/or recombinase- mediated integration (e.g., serine recombinase fC31 integrase). In such embodiments, at least a first donor polynucleotide template can be integrated into the genome of the pleiopluripotent cell at the at least first incorporated recognition site using an integrase. [0320] In another embodiment, a method of generating a pleiopluripotent cell (e.g., a second generation pleiopluripotent cell) includes integrating, into the genome of the pleiopluripotent cell at an at least first incorporated recognition site, at least a first donor polynucleotide template, by introducing into the cell: (i) the first donor polynucleotide template, wherein the first donor polynucleotide template is comprised of one or more orthogonal integration recognition sites, and (ii) an integrase, whereby the donor polynucleotide is integrated into the pleiopluripotent stem cell at the at least one incorporated genomic integration recognition sites by the integrase; thereby producing a second generation pleiopluripotent cell. [0321] In another embodiment, a method of generating a pleiopluripotent cell (e.g., a third generation pleiopluripotent cell) includes integrating, into the genome of the pleiopluripotent cell at an at least first incorporated recognition site, at least a first donor polynucleotide template, by introducing into the cell: (i) the first donor polynucleotide template, wherein the first donor polynucleotide template is comprised of one or more orthogonal integration recognition sites, and (ii) an integrase, whereby the donor polynucleotide is integrated into the pleiopluripotent stem cell at the at least one incorporated genomic integration recognition sites by the integrase; and (b) site- specifically incorporating a second integration recognition site into the genome of the pleiopluripotent cell, thereby producing a third generation pleiopluripotent cell. [0322] In another embodiment, a method of generating a pleiopluripotent cell (e.g., a fourth generation pleiopluripotent cell) includes integrating, into the genome of the pleiopluripotent cell at an at least the first incorporated recognition site, at least a first donor polynucleotide template, by introducing into the cell: (i) the first donor polynucleotide template, wherein the first donor polynucleotide template is comprised of one or more orthogonal integration recognition sites, and (ii) an integrase, whereby the donor polynucleotide is integrated into the pleiopluripotent stem cell at the at least one incorporated genomic integration recognition sites by the integrase; (b) site- specifically incorporating a second integration recognition site into the genome of the pleiopluripotent cell; and (c) integrating a second donor polynucleotide template into the pleiopluripotent cell genome at the second incorporated integration recognition site, by delivering into the cell: (i) the second donor polynucleotide template, wherein the donor polynucleotide template is comprised of one or more integration recognition sites orthogonal to the second integration recognition site, and (ii) an integrase, whereby the donor polynucleotide is integrated into the pleiopluripotent stem cell at the second incorporated genomic integration recognition sites by the integrase; thereby producing a fourth generation pleiopluripotent cell. In some embodiments, incorporation of the second integration recognition site into the pleiopluripotent cell genome is performed concurrently with integration of the second donor polynucleotide template into the pleiopluripotent cell genome. [0323] In some embodiments, an integration recognition site (i.e., beacon) is incorporated into a pleiopluripotent cell genome by delivering into the cell: (i) a gene editor protein (or a polynucleotide encoding a gene editor protein) or a prime editor fusion protein (or a polynucleotide encoding a prime editor fusion protein), wherein the gene editor protein or prime editor fusion protein is capable of incorporating the integration recognition site into the genome, and (ii) two guide RNAs (e.g., two atgRNAs), wherein each of the two guide RNA encodes all or part of an integrase target recognition site. Further, the method includes integrating a donor polynucleotide template into the pleiopluripotent cell genome at the incorporated target recognition site by delivering into the cell: (i) the donor polynucleotide template, wherein the donor polynucleotide template is comprised of an integration target site, and an integrase, whereby the donor polynucleotide is integrated into the pleiopluripotent cell at the incorporated integration recognition site by the integrase, thereby producing a genetically modified pleiopluripotent cell (e.g., a second generation pleiopluripotent cell). In some embodiments, incorporation of the integration recognition site (i.e., beacon) into the pleiopluripotent cell genome is performed concurrently with integration of the donor polynucleotide template into the pleiopluripotent cell genome.

Donor Polynucleotide Template [0363] In certain embodiments, a cellular integrated polynucleotide (i.e., donor polynucleotide template) encodes for one or more inducible suicide genes, one or more exogenous polypeptides capable of modulating an immune response, and one or more adapters (tags), or a combination thereof. (See, e.g., FIG.3A). [0364] In some embodiments, a cellular integrated polynucleotide (i.e., donor polynucleotide template) includes one or more integration recognition sites. In some embodiments, the one or more integration recognition sites encoded in the cellular integrated polynucleotide (i.e., donor polynucleotide template) can be used to integrate a second cellular integrated polynucleotide (e.g., a second donor polynucleotide template) in the genomic loci where the first cellular integrated polynucleotide integrated. In some embodiments, the one or more integration recognition sites encoded in the cellular integrated polynucleotide (i.e., donor polynucleotide template) can be used to excise all or a portion of the cellular integrated polynucleotide integrated into pleiopluripotent cell genome. [0365] In some embodiments, expression of the one or more inducible suicide genes, one or more exogenous polypeptides capable of modulating an immune response, or a combination thereof, is driven by a pleiopluripotent cell-specific regulatory elements (e.g., a promoter, an enhancer, or a combination thereof).

In some embodiments, the second donor polynucleotide template integrated into pleiopluripotent cell genome is at least 35 kilobases (kb). 6.11.3.1 Inducible Suicide Genes [0369] In certain embodiments, the cellular integrated polynucleotide (i.e., donor polynucleotide template) encodes for one or more inducible suicide genes. As used herein, the term “inducible suicide gene” refers to an engineered polypeptide designed to prevent the adverse events of cell therapy. In some embodiments, the inducible suicide gene is conditionally controlled to address adverse events of cell therapy (e.g., safety concerns). Conditional regulation can include control through a small molecule-mediated post-translational activation, tissue-specific regulation, temporal transcriptional regulation, or a combination thereof. The inducible suicide gene could mediate induction of apoptosis, inhibition of protein synthesis, DNA replication, growth arrest, transcriptional and post-transcriptional genetic regulation and/or antibody-mediated depletion. In some embodiments, the inducible suicide gene is activated by an exogenous molecule, e.g., a prodrug, that when activated, triggers apoptosis and/or cell death of a therapeutic cell. Non- limiting examples of inducible suicide genes include to suicide genes such as caspase 9 (or caspase 3 or 7), herpes simplex virus thymidine kinase (HSV-TK), cytosine deaminase, modified EGFR, nitroreductase, purine nucleoside phosphorylase, horseradish peroxidase, a HER1 transgene, a RQR8 transgene, or a combination thereof. In this strategy, a prodrug (e.g., an exogenous molecule) that is administered in the event of an adverse event is activated by the suicide-gene product and kills the transduced cell. [0370] In one embodiment, the one or more inducible suicide genes is caspase9. In one embodiment, the one or more inducible suicide genes comprises two caspase9 proteins where each caspase9 protein is operably linked to a different promoter sequence (See FIG. 3A). Relying on two different promoters enables both time and tissue specific control over expression of each caspase9 protein. In one embodiment, each caspase 9 protein is fused to a different controllable domain (e.g., FKBP or mFRM and FKBP), thereby generating controllable caspase9 proteins. This enables individual control over activity of each caspase9 protein (see FIG. 4). Activity of a controllable caspase9 proteins is controlled using an exogenous molecule. In one embodiment, the exogenous molecule is AP20187 (or an analog thereof). AP20187 enables homodimerization of Caspase9-FKBP fusions. A non-limiting example, as shown in FIG.4, illustrates caspase9-FKBP fusions where expression is driven by a nanog promoter. In this case, the caspase9 FKBP protein is expressed while the cells are in a pluripotent state. Contacting the cell with AP20187 during the pluripotent state results in cell death. In some embodiments, the exogenous molecule is AP21967 (or an analog thereof). A non-limiting example, as shown in FIG.4, illustrate caspase9-FKBP and caspase9-mFRB where expression is driven by a beta-actin promoter (or another constitutively active promoter). In this case, the Caspase9-FKBP and Caspase9-mFRB fusion are expressed constitutively. Therefore, contacting the cells with the AP21967 results in cell death. Either AP20187 and/or AP21967 can be administered to a subject who was previously been administered cells containing the HSV-TK gene. [0371] In one embodiment, the one or more inducible suicide genes is herpes simplex virus thymidine kinase (HSV-TK). HSV-TK converts ganciclovir into a toxic product and allows selective elimination of cells expressing the HSV-TK gene. Ganciclovir can be administered to a subject who was previously been administered cells containing the HSV-TK gene. In such cases, ganciclovir is used to eliminate the previously administered cells. [0372] In one embodiment, the donor polynucleotide templates comprise three suicide genes, including a first caspase9 protein fused to a FKBP domain operably linked to a Nanog promoter, a second caspase9 protein used to a mFRB domain and a FKBP domain operably linked to a Beta- actin promoter, and a thymidine kinase (see, e.g. FIG. 3A). In some embodiments, each of the inducible suicide genes is operably linked to a promoter. In some embodiments, the thymidine kinase is linked to one of the caspase9 proteins by a 2A self-cleaving peptide (e.g., a P2A, E2A,T2A, and F2A) or an internal ribosome entry site (IRES) (see, e.g., FIG.3A). [0373] In some embodiments, integrating a donor polynucleotide template encoding one or more inducible suicide genes into the pleiopluripotent cell genome at the one or more incorporated target recognition sites results in increased expression of the one or more inducible suicide genes as compared to a pluripotent stem genome not having a donor polynucleotide template integrated into the cell’s genome at the one or more incorporated target recognition sites. In some embodiments, integrating a donor polynucleotide template encoding one or more inducible suicide genes into the pleiopluripotent cell genome at the one or more incorporated target recognition sites results in increased expression of at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 150%, 200%, 250%, 300%, 350%, 400%, 450%, 500%, or more of the one or more inducible suicide genes as compared to a pluripotent stem genome not having a donor polynucleotide template integrated into the cell’s genome at the one or more incorporated target recognition sites. [0374] In some embodiments, the encoded one or more inducible suicide genes further comprises an integrase target recognition site. In some embodiments, the encoded one or more inducible suicide genes further comprises at least two integrase target recognition sites. In certain embodiments, the one or more integrase target recognition sites flank the encoded one or more inducible suicide genes. In certain embodiments, the flanking integrase target recognition sites allow for excision of the one or more inducible suicide genes. 6.11.3.2 Exogenous Polypeptides Capable of Modulating an Immune Response [0375] In certain embodiments, the one or more exogenous polypeptides capable of modulating an immune response prevents an immune response to the pleiopluripotent cells or cells derived therefrom. In some embodiments, the one or more exogenous polypeptides capable of modulating an immune response prevent an immune response to the pleiopluripotent cells (or cells derived therefrom) by inhibiting, blocking, or preventing recognition of the pleiopluripotent cell by macrophages, T-cells, Natural Killer (NK)-cells, antigen-presenting cells, or a combination thereof. [0376] In some embodiments, the one or more exogenous polypeptides capable of modulating an immune response is selected from: CD47, PDL-1, HLA-E, HLA-G, HACD16, 41BBL, CD3, CD4, CD8, CD137, CD80, and A2AR, or a combination thereof. [0377] In some embodiments, integrating a donor polynucleotide template encoding one or more exogenous polypeptides capable of modulating an immune response into the pleiopluripotent cell genome at the one or more incorporated target recognition sites results in increased expression of the one or more polypeptides capable of modulating an immune response as compared to a pluripotent stem genome not having a donor polynucleotide template integrated into the cell’s genome at the one or more incorporated target recognition sites. In some embodiments, integrating a donor polynucleotide template encoding one or more exogenous polypeptides capable of modulating an immune response into the pleiopluripotent cell genome at the one or more incorporated target recognition sites results in increased expression of at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100%, 150%, 200%, 250%, 300%, 350%, 400%, 450%, 500%, or more of the one or more inducible suicide genes as compared to a pluripotent stem genome not having a donor polynucleotide template integrated into the cell’s genome at the one or more incorporated target recognition sites. [0378] In certain embodiments, the cellular integrated polynucleotide (i.e., donor polynucleotide template) encodes for two or more exogenous polypeptides capable of modulating an immune response where the sequence encoding the two or more exogenous polypeptides are separated by a 2A self-cleaving peptide (e.g., a P2A, E2A,T2A, and F2A). In other embodiments, the sequences encoding the two or more exogenous polypeptides are separated by an internal ribosome entry site (IRES). In some embodiments, a cellular integrated polynucleotide includes: CD47, PDL-1, and B2M-HLA-E. In such cases, the sequences encoding CD47, PDL-1 and B2M- HLA-E are separated by either a 2A self-cleaving peptide (e.g., a P2A, E2A,T2A, and F2A) or an IRES sequence. A non-limiting example of a cellular integrated polynucleotide is described in FIG.3A. [0379] In certain embodiments, the encoded one or more exogenous polypeptides capable of modulating an immune response further comprises an integrase target recognition site. In some embodiments, the encoded one or more exogenous polypeptides capable of modulating an immune response further comprises at least two integrase target recognition sites. In certain embodiments, the one or more integrase target recognition sites flank the encoded one or more exogenous polypeptides capable of modulating an immune response. In certain embodiments, the flanking integrase target recognition sites allow for excision of the one or more exogenous polypeptides capable of modulating an immune response. [0380] In some embodiments, the one or more exogenous polypeptides capable of modulating an immune response are capable of serving as a safety switch target. In some embodiments, the one or more exogenous polypeptides can be targeted with an antibody that is capable of specifically binding to the one or more exogenous polypeptides, thereby blocking the polypeptides ability to prevent an immune response to the pleiopluripotent cells, or cells derived therefrom. For example, a pleiopluripotent cell comprising an exogenous CD47 on it surface can be contacted with an anti- CD47 antibody, wherein the anti-CD47 antibody blocks CD47 interaction with macrophage signal regulatory protein (SIRPα), thereby allowing recognition and elimination of the cell by macrophages. In another example, the pleiopluripotent cell comprising an exogenous PD-L1 on it surface can be contacted with an anti-PD-L1 antibody, wherein the anti-PD-L1 antibody blocks PD-L1 interaction with PD-1, thereby allowing recognition and elimination of the cell by T cells. 6.11.3.3 Adapters/Tags [0381] In some embodiments, a first or second cellular integrated polynucleotide (i.e., a first or second donor polynucleotide template) includes a sequence encoding a tag that enables isolation of the pleiopluripotent cell. The tag can be a stand-alone molecule such as a polypeptide expressed on the surface of the pleiopluripotent cell or a cell-derived from the pleiopluripotent cell. Non- limiting example of stand-alone tags includes non-natively expressed receptors (e.g., nerve truncated growth factor receptor and truncated nerve growth factor receptor). [0382] In other cases, the tag can be an amino acid sequence fused to an amino acid sequence of an endogenous protein that is expressed by a pleiopluripotent cell or a cell-derived from the pleiopluripotent cell. Non-limiting examples of tags that can be used to isolate a cell having a first or second cellular integrated polynucleotide include an ALFA tag system (e.g., SRLEEELRRRLTE (SEQ ID NO: 615)). In one non-limiting example, the ALFA tag is fused to the N-terminus of CD47 (see FIG.3A). [0383] In one embodiment, the first or second cellular integrated polynucleotide includes a sequence encoding an ALFA tag fused to one or more polypeptide expressed on the surface of the cell (e.g., one of more of the exogenous polypeptides capable of modulating an immune response). In such cases, a nanobody designed to bind specifically to the ALFA can be used to bind and isolate the pleiopluripotent cells having the tag on the surface. In some cases, an ALFA tag can be used to identify pleiopluripotent cells that include the first and/or second cellular integrated polynucleotide integrated into its genome. In some cases, an ALFA nanobody (NbALFA) is fused to one or more polypeptides on the surface of the cell, one or more ALFA tagged polypeptides can be used to engage with NbALFA fusion polypeptides for therapeutic purposes. 6.11.4. Additional Integration Recognition Sites Incorporated into Pleiopluripotent Cell Genome [0384] In some embodiments, an additional integration recognition site is incorporated into a pleiopluripotent cell genome by delivering into the cell: (i) a gene editor protein (or a polynucleotide encoding a gene editor protein) or a prime editor fusion protein (or a polynucleotide encoding a prime editor fusion protein), wherein the gene editor protein or prime editor fusion protein is capable of incorporating the integration recognition site into the genome, (ii) at least a first pair of guide RNAs, wherein the first paired guide RNAs have domains that are capable of guiding the gene editor protein or prime editor fusion protein to nick the pleiopluripotent stem cell genome at sites respectively flanking the specific incorporation site, and at least one of the two paired guide RNAs is an atgRNA that further includes a reverse transcriptase (RT) template that comprises at least a portion of the first integration recognition site, and the atgRNAs collectively encode the entirety of the first integration recognition site, whereby the first integration recognition site is site-specifically incorporated into the genome of the pleiopluripotent stem cell. [0385] In some embodiments, the additional integration recognition site is incorporated into the pleiopluripotent cell genome at a locus encoding an exon. In such embodiments, the exon is coding sequence of a gene of interest, wherein incorporation of the integration recognition site into the exon is capable of reducing or deleting expression of the gene of interest. [0386] In some embodiments, the additional integration recognition is incorporated into the pleiopluripotent cell genome at a locus, disruption of which is capable of reducing allogeneic immune response to the pleiopluripotent stem cell or a cell matured from the pleiopluripotent cell. Non-limiting examples of loci, disruption of which is capable of reducing allogeneic immune response to the pleiopluripotent stem cell or a cell matured from the pleiopluripotent cell, are described herein. [0387] Incorporating an additional integration recognition site into a pleiopluripotent cell genome enables subsequent round of genetic modification of the pleiopluripotent cell genome. For example, in a subsequent round of genetic modification, a second donor polynucleotide can be integrated at the genomic locus where the additional integration recognition sites were incorporated in the early round of editing. [0388] In some embodiments, a genetically modified pleiopluripotent cell comprises one, two, three, four, five, six, seven, eight, nine, ten, or more integration recognition sites. In some embodiments, the at least one, at least two, at least three, at least four, at least five or more of the integration recognition sites can be used for placing a second donor polynucleotide template into the pleiopluripotent cell genome. 6.11.5. A Second Donor Polynucleotide Template [0389] In certain embodiments, a second donor polynucleotide template (e.g., a second cellular integrated polynucleotide) that encodes for one or more of the therapeutic agents described herein is incorporated into the pleiopluripotent cell genome. In such cases, the second cellular integrated polynucleotide (i.e., second donor polynucleotide template) can be incorporated into the pleiopluripotent cell genome at an additional integration recognition site (e.g., any of the additional integration recognition sites described herein). [0390] In some embodiments, a second donor polynucleotide template encodes transcription factors, receptors, chimeric antigen receptors, signaling molecules, secreted proteins, cytokines, enzymes, or proteins promoting engraftment, trafficking, homing, viability, self-renewal, and persistence and/or survival of the iPSCs or cells derived from the iPSC. [0391] In some embodiments, a second donor polynucleotide template encodes for one or more of a chimeric antigen receptor, a T cell receptor, a cytokine receptor, a chemokine receptor, or a modified receptor. In some embodiments, the second donor polynucleotide template encodes for an exogenous T cell receptor. In some embodiments, the second cellular integrated polynucleotide encodes for a secreted cytokine. In some embodiments, the second donor polynucleotide template encodes for a recombinant protein. In some embodiments, the second donor polynucleotide template further comprises one or more of a co-stimulatory receptor such suitable co-stimulatory signaling regions are also well known in the art, and include members of the B7/CD28 family such as B7-1, B7-2, E7-H1, B7-H2, E7-H3, B7-H4, B7-H6, B7-H7, BTLA, CD28, CTLA-4, Gi24, ICOS, PD-1, PD-L2 or PDCD6; or ILT/CD85 family proteins such as LILRA3, LILRA4, LILRB1, LILRB2, LILRB3 or LILRB4; or tumor necrosis factor (TNF) superfamily members such as 4-1BB, BAFF, BAFF R, CD27, CD30, CD40, DR3, GITR, HVEM, LIGHT, Lymphotoxin-alpha, OX40, RELT, TACI, TL1A, TNF-alpha or TNF RII; or members of the SLAM family such as 2B4, BLAME, CD2, CD2F-10, CD48, CD8, CD84, CD229, CRACC, NTB-A or SLAM; or members of the TIM family such as TIM-1, TIM-3 or TIM-4; or other co- stimulatory molecules such as CD7, CD96, CD160, CD200, CD300a, CRTAM, DAP12, Dectin- 1, DPPIV, EphB6, Integrin alpha 4 beta 1, Integrin alpha 4 beta 7/LPAM-1, LAG-3 or TSLP R. [0392] The selection of the co-stimulatory signaling regions may be selected depending upon the particular use intended for the transformed cells. In particular, the co-stimulatory signaling regions selected for those which may work co-operatively or synergistically together. For example, the co-stimulatory signaling regions may be selected from CD28, CD27, ICOS, 4-1BB, OX40, CD30, GITR, HVEM, DR3 or CD40. [0393] In some embodiments, the encoded one or more chimeric antigen receptor, T cell receptor, cytokine receptor, chemokine receptor, or modified receptor, further comprises one or more integrase target recognition site. In some embodiments, the encoded one or more chimeric antigen receptor, T cell receptor, cytokine receptor, chemokine receptor, or modified receptor, further comprises at least two integrase target recognition sites. In certain embodiments, the one or more integrase target recognition sites flank the encoded one or more chimeric antigen receptor, T cell receptor, cytokine receptor, chemokine receptor, or modified receptor. In certain embodiments, the flanking integrase target recognition sites allow for excision of any inserted genetic sequence. [0394] In some embodiments, a first or second donor polynucleotide template encodes one or more HLA Class I proteins, one or more HLA Class II proteins, or a combination thereof. In some embodiments, the first or second donor polynucleotide template encodes one or more HLA Class I proteins or one or more HLA Class II proteins that has reduced expression (e.g., due to a mutation or due to genetic ablation using a knockdown-mediated technique) in the pleiopluripotent cell or cell differentiated from the pleiopluripotent cell. In some embodiments, the HLA Class 1 protein is a B2M protein. In some embodiments, a first or second donor polynucleotide template includes an inducible promoter that controls expression of the one or more HLA Class I proteins, the one or more HLA Class II proteins, or a combination thereof. In such cases, the one or more HLA Class I proteins or one or more HLA Class II proteins can be “switched-on” at a later time point. Non-limiting examples of inducible promoter sequences that can be used in the methods described herein include a tetracycline-inducible promoter, an alcohol regulated promoter (e.g., AlcA promoter and AlcR activator), and steroid-regulated promoter (e.g., a LexA promoter and a XVE activator), a temperature-inducible promoter (e.g., Hsp70 or Hsp90), and a light-inducible promoter (e.g., FixK2 promoter and blue-light sensing protein YFI). In some embodiments, the inducible promoter is a tetracycline inducible promoter. [0395] A non-limiting example of a donor polynucleotide template that can be incorporated into the genome of a pleiopluripotent cell using the methods described herein includes the donor polynucleotide templates are as described in FIGs.3A-3B, FIG.17, and FIG.18 (see also SEQ ID NOs: 616 and 617). [0396] In some embodiments, a first or second cellular integrated polynucleotide (i.e., a first or second donor polynucleotide template) that includes an inducible promoter that controls expression of the one or more HLA Class I proteins, the one or more HLA Class II proteins, or a combination thereof, is incorporated into a pleiopluripotent cell’s genome at locus that allows for inducible gene expression can be “switched-on” at a later time point. Non-limiting criteria for genomic loci that enable inducible gene expression at a later time point include those that remain accessible to transcriptional machinery (i.e., capable of being expressed) when the cell is in a pluripotent state as well as when the cells are differentiated to one or more of the cell types described herein (e.g., a hematopoietic cell, a neuronal cell, a cardiac cell, and a beta-cell). A non- limiting example of a genomic loci that fits this criteria is the CIITA locus. 6.11.6. Safe Harbor Loci and Genomic Safe Harbor [0397] In some embodiments, an integration recognition site (i.e., beacon) is incorporated into a pleiopluripotent cell genome at a safe harbor locus or a genomic safe harbor. In such cases, the donor polynucleotide template is integrated into the pleiopluripotent cell genome at the safe harbor loci or the genomic safe harbor. [0398] In some embodiments, an additional integration recognition site (e.g., a second integration recognition site) is incorporated into a pleiopluripotent cell genome at a safe harbor locus or a genomic safe harbor. In such cases, the second donor polynucleotide template described herein) is integrated into the pleiopluripotent cell genome at the safe harbor loci or the genomic safe harbor. [0399] Safe harbor loci, safe harbor site, and genomic safe can be used interchangeably. In some embodiments, a safe harbor locus is region of the human genome (e.g., intragenic or extragenic regions) that are able to accommodate predictable expression of newly integrated DNA without adverse effects on the host cell or organism. In typical embodiments, a useful safe harbor must permit sufficient transgene expression to yield desired levels of the proteins encoded in the donor template polynucleotide. In some embodiments, a safe harbor also must not predispose cells to malignant transformation nor alter cellular functions. Non-limiting examples of criteria that describe a safe harbor loci and/or genomic safe harbor include (i) absence of disruption of regulatory elements or genes, as judged by sequence annotation; is an intergenic region in a gene dense area, or a location at the convergence between two genes transcribed in opposite directions; (ii) keep distance to minimize the possibility of long-range interactions between vector-encoded transcriptional activators and the promoters of adjacent genes, particularly cancer-related and microRNA genes; and (iii)ubiquitous transcriptional activity, as reflected by broad spatial and temporal expression patterns (e.g., as measured by expression analysis), chromatin accessibility patterns (e.g., as measured by ATAC-seq), or methylation patterns (e.g., as measured by whole- genome bisulfite sequencing), indicating ubiquitous transcriptional activity. In typical embodiments, it is important for the safe harbor loci or genomic safe harbor to have the potential for ubiquitous expression because pleiopluripotent cells during differentiation experience changes in chromatin accessibility and/or remodeling that can lead to silencing of some loci and potential activation of others. [0400] Non-limiting examples of genomic safe harbor include those as described in Aznauryan et al. (Cell Reports Methods, Discovery and validation of human genomic safe harbor sites for gene and cell therapies, 2(1): 100154 (2022); see Table S1, including Genomic coordinates: chromosome 1: 195338589-195818588 and chromosome 3: 22720711-22761389). [0401] Other non-limiting examples of safe harbor sites include adeno-associated virus site 1 (AAVS1), the chemokine (CC motif) receptor 5 ( CCR5 ) gene locus, the human orthologue of the mouse ROSA26 locus, collagen and FITRP. A frequently used human SHS is the AAVS1 site on chromosome 19q, initially identified as a site for recurrent adeno-associated virus insertion. Another locus comprises the human homolog of the murine Rosa26 locus. Yet another SHS comprises the human H11 locus on chromosome 22. In some cases, a complete gene may be prohibitively large and replacement of an entire gene impractical. 6.11.7. Therapeutic Agents [0402] This disclosure provides compositions and methods for correcting or replacing genes or gene fragments (including introns or exons) or inserting genes in new locations. In certain embodiments, such a method comprises recombination or integration of a therapeutic agent into a safe harbor site (SHS) (e.g., any of the safe harbor sites described herein).

[0404] In certain embodiments, correcting or replacing genes or gene fragment (including introns and exons) includes integrating the corrective gene or fragment (the therapeutic agent) into one or more additional integration recognition sites previously incorporated into the pleiopluripotent cell genome. For example, the genes and targets described herein are encoded in the first donor template nucleotide, the second donor template nucleotide, or both. In such cases, the genes and targets described herein are integrated into the pleiopluripotent cell genome at the corresponding loci in which the integration target recognition sequences have been integrated (e.g., the one or more integration recognition sites or the one or more additional integration recognition sites). [0405] In certain embodiments, methods and compositions of the invention are adapted to differentiate muscle cells to cardiomyocytes for Duchene Muscular Dystrophy (DMD). The dystrophin gene is the largest gene in the human genome, spanning ∼2.3 Mb of DNA. DMD is composed of 79 exons resulting in a 14-kb full-length mRNA. Common mutations include mutations that disrupt the reading frame of generate a premature stop codon. An aspect of DMD that lends it to gene editing as a therapeutic approach is the modular structure of the dystrophin protein. Redundancy in the central rod domain permits the deletion of internal segments of the gene that may harbor loss-of-function mutations, thereby restoring the open reading frame (ORFs).

An aspect of DMD that lends it to gene editing as a therapeutic approach is the modular structure of the dystrophin protein. Redundancy in the central rod domain permits the deletion of internal segments of the gene that may harbor loss-of-function mutations, thereby restoring the open reading frame (ORFs). [0410] In some embodiments, recombination will be into safe harbor sites (SHS). A frequently used human SHS is the AAVS1 site on chromosome 19q, initially identified as a site for recurrent adeno-associated virus insertion. In some embodiments, the site is the human homolog of the e murine Rosa26 locus (pubmed.ncbi.nlm.nih.gov/18037879). In some embodiments, the site is the human H11 locus on chromosome 22. Proposed target cells for recombination include stem cells for example induced pluripotent stem cells (iPSCs) and cells at various stages of differentiation. In some cases, a complete gene may be prohibitively large and replacement of an entire gene impractical. In such instances, rescuing mutants by recombining in corrected gene fragments with the methods and systems described herein is a corrective option. [0411] In some embodiments, correcting mutations in exon 44 (or 51) by recombining in a corrective coding sequence downstream of exon 43 (or 50), using the methods and systems described herein is a corrective option.

Proposed validation is detection of persistent OTC mRNA and protein expression in transduced cells. [0418] Phenylketonuria, also called PKU, is a rare inherited disorder that causes an amino acid called phenylalanine to build up in the body.

It is a replicon, such as a plasmid, phage, or cosmid, into which another DNA segment may be inserted so as to bring about the replication of the inserted segment. Generally, a vector is capable of replication when associated with the proper control elements. In general, the term "vector" refers to a nucleic acid molecule capable of transporting another nucleic acid to which it has been linked. Vectors include, but are not limited to, nucleic acid molecules that are single-stranded, double- stranded, or partially double-stranded; nucleic acid molecules that comprise one or more free ends, no free ends (e.g. circular); nucleic acid molecules that comprise DNA, RNA, or both; and other varieties of polynucleotides known in the art. One type of vector is a "plasmid," which refers to a circular double stranded DNA loop into which additional DNA segments can be inserted, such as by standard molecular cloning techniques. Another type of vector is a viral vector, wherein virally- derived DNA or RNA sequences are present in the vector for packaging into a virus (e.g. retroviruses, replication defective retroviruses, adenoviruses, replication defective adenoviruses, and adeno-associated viruses (AAVs)). Viral vectors also include polynucleotides carried by a virus for transfection into a host cell. Certain vectors are capable of autonomous replication in a host cell into which they are introduced (e.g. bacterial vectors having a bacterial origin of replication and episomal mammalian vectors). Other vectors (e.g., non-episomal mammalian vectors) are integrated into the genome of a host cell upon introduction into the host cell, and thereby are replicated along with the host genome. Moreover, certain vectors are capable of directing the expression of genes to which they are operatively-linked. Such vectors are referred to herein as "expression vectors." Vectors for and that result in expression in a eukaryotic cell can be referred to herein as "eukaryotic expression vectors." Common expression vectors of utility in recombinant DNA techniques are often in the form of plasmids. [0516] Recombinant expression vectors can comprise a nucleic acid of the invention in a form suitable for expression of the nucleic acid in a host cell, which means that the recombinant expression vectors include one or more regulatory elements, which may be selected on the basis of the host cells to be used for expression, that is operatively-linked to the nucleic acid sequence to be expressed. Within a recombinant expression vector, "operably linked" is intended to mean that the nucleotide sequence of interest is linked to the regulatory element(s) in a manner that allows for expression of the nucleotide sequence (e.g. in an in vitro transcription/translation system or in a host cell when the vector is introduced into the host cell). With regards to recombination and cloning methods, mention is made of U.S. patent application Ser. No.10/815,730, published Sep.2, 2004 as US 2004-0171156 A1, the contents of which are herein incorporated by reference in their entirety. [0517] Vector delivery, e.g., plasmid, viral delivery: The CRISPR enzyme, for instance a Type V protein such as C2c1 or C2c3, and/or any of the present RNAs, for instance a guide RNA, can be delivered using any suitable vector, e.g., plasmid or viral vectors, such as adeno associated virus (AAV), lentivirus, adenovirus or other viral vector types, or combinations thereof. Effector proteins and one or more guide RNAs can be packaged into one or more vectors, e.g., plasmid or viral vectors. [0518] The promoter used to drive nucleic acid-targeting effector protein coding nucleic acid molecule expression can include: AAV ITR can serve as a promoter: this is advantageous for eliminating the need for an additional promoter element (which can take up space in the vector). The additional space freed up can be used to drive the expression of additional elements (gRNA, etc.). Also, ITR activity is relatively weaker, so can be used to reduce potential toxicity due to over expression of nucleic acid-targeting effector protein. For ubiquitous expression, can use promoters: CMV, CAG, CBh, PGK, SV40, Ferritin heavy or light chains, etc. For brain or other CNS expression, can use promoters: Synapsin I for all neurons, CaMKII alpha for excitatory neurons, GAD67 or GAD65 or VGAT for GABAergic neurons, etc. For liver expression, can use Albumin promoter. For lung expression, can use SP-B. For endothelial cells, can use ICAM. For hematopoietic cells can use IFNbeta or CD45. For Osteoblasts can use OG-2. [0519] The promoter used to drive guide RNA can include: Pol III promoters such as U6 or H1 Use of Pol II promoter and intronic cassettes to express guide RNA Adeno Associated Virus (AAV) [0520] Nucleic acid-targeting effector protein and one or more guide RNA can be delivered using adeno associated virus (AAV), lentivirus, adenovirus or other plasmid or viral vector types, in particular, using formulations and doses from, for example, U.S. Pat. No.8,454,972 (formulations, doses for adenovirus), U.S. Pat. No.8,404,658 (formulations, doses for AAV) and U.S. Pat. No. 5,846,946 (formulations, doses for DNA plasmids) and from clinical trials and publications regarding the clinical trials involving lentivirus, AAV and adenovirus. For examples, for AAV, the route of administration, formulation and dose can be as in U.S. Pat. No. 8,454,972 and as in clinical trials involving AAV. For Adenovirus, the route of administration, formulation and dose can be as in U.S. Pat. No. 8,404,658 and as in clinical trials involving adenovirus. For plasmid delivery, the route of administration, formulation and dose can be as in U.S. Pat. No. 5,846,946 and as in clinical studies involving plasmids. Doses may be based on or extrapolated to an average 70 kg individual (e.g., a male adult human), and can be adjusted for patients, subjects, mammals of different weight and species. Frequency of administration is within the ambit of the medical or veterinary practitioner (e.g., physician, veterinarian), depending on usual factors including the age, sex, general health, other conditions of the patient or subject and the particular condition or symptoms being addressed. The viral vectors can be injected into the tissue of interest. For cell- type specific genome modification, the expression of nucleic acid-targeting effector can be driven by a cell-type specific promoter. For example, liver-specific expression might use the Albumin promoter and neuron-specific expression (e.g., for targeting CNS disorders) might use the Synapsin I promoter. [0521] Another useful method to deliver proteins, enzymes, and guides to a pluripotent stem cell comprises transfection of messenger RNA (mRNA). Examples of mRNA delivery methods and compositions that may be utilized in the present disclosure including, for example, PCT/US2014/028330, US8822663B2, NZ700688A, ES2740248T3, EP2755693A4, EP2755986A4, WO2014152940A1, EP3450553B1, BR112016030852A2, and EP3362461A1. Expression of CRISPR systems in particular is described by WO2020014577. Each of these publications are incorporated herein by reference in their entireties. Additional disclosure hereby incorporated by reference can be found in Kowalski et al., “Delivering the Messenger: Advances in Technologies for Therapeutic mRNA Delivery,” Mol Therap., 2019; 27(4): 710-728. [0522] In some embodiments, one or more vectors described herein are used to produce a non- human transgenic animal or transgenic plant. In some embodiments, the transgenic animal is a mammal, such as a mouse, rat, or rabbit. In certain embodiments, the organism or subject is a plant. In certain embodiments, the organism or subject or plant is algae. Methods for producing transgenic plants and animals are known in the art, and generally begin with a method of cell transfection, such as described herein. [0523] In some embodiments, the method comprises sampling a cell or population of cells from a human or non-human animal or plant (including micro-algae) and modifying the cell or cells. Culturing may occur at any stage ex vivo. The cell or cells may even be re-introduced into the non-human animal or plant (including micro-algae). [0524] Examples of target polynucleotides include a sequence associated with a signaling biochemical pathway, e.g., a signaling biochemical pathway-associated gene or polynucleotide. Examples of target polynucleotides include a disease associated gene or polynucleotide. A "disease-associated" gene or polynucleotide refers to any gene or polynucleotide which is yielding transcription or translation products at an abnormal level or in an abnormal form in cells derived from a disease-affected tissues compared with tissues or cells of a non-disease control. It may be a gene that becomes expressed at an abnormally high level; it may be a gene that becomes expressed at an abnormally low level, where the altered expression correlates with the occurrence and/or progression of the disease. A disease-associated gene also refers to a gene possessing mutation(s) or genetic variation that is directly responsible or is in linkage disequilibrium with a gene(s) that is responsible for the etiology of a disease. The transcribed or translated products may be known or unknown and may be at a normal or abnormal level. [0525] In some embodiments, the genetically modified cell are non-dividing cells (e.g., where cell growth has been arrested) prior to being contacted with the gene editing reagents (e.g., gene editor protein or a polynucleotide encoding a gene editor protein, one or more guide RNA, and optionally a nicking gRNA). In some embodiments, the genetically modified cells are terminally differentiated, non-dividing cells prior to being contacted with the gene editing reagents (e.g., gene editor protein or a polynucleotide encoding a gene editor protein, one or more guide RNA, and optionally a nicking gRNA). In some embodiments, the genetically modified cells are dividing cells. 7. ADDITIONAL EMBODIMENTS [0526] Embodiment 1.

8.2. Example 1: Dual atgRNA-mediated beacon placement within the B2M or CIITA loci in iPSC [0604] To demonstrate and optimize attB beacon placement (i.e., incorporation into the genome of the integrase target recognition site) at the B2M locus or the CIITA locus within iPSCs, a dual atgRNA approach to beacon placement was used. A non-limiting example of a dual atgRNA approach for beacon placement within an iPSC genome is as shown in FIG.6 (left panel showing example atgRNAs and right panel showing a schematic of the dual atgRNA approach). The dual atgRNAs (forward and reverse atgRNAs) each included a portion of the 38 bp attB insertion site within a segment of the reverse transcriptase template (see, e.g., FIGs.7A-7B) (Table 12). The protospacer sequences (i.e., a sequence/domain capable of guiding the gene editor protein or prime editor fusion protein to site-specifically nick the iPSC genome) were initially selected from the literature (see FIG.6 and FIG.9). [0605] A non-limiting example of a method of generating an iPSC having an integration recognition site site-specifically integrated into the iPSC genome is shown in FIG.8. [0606] iPSC lines ACS-1030 (iPSC1) and ACS-1026 (iPSC2) were purchased from ATCC and cultured as undifferentiated iPSCs grown on Cell Basement Membrane (ATCC)-coated plates in Pluripotent Stem Cell SFM XF/FF media (ATCC). Undifferentiated iPSCs were electroporated with prime editor fusion protein (2 micrograms mRNA encoding prime editor fusion protein) and atgRNA (50 picomoles). Electroporation was performed using a Neon Transfection System (ThermoFisher) with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane-coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM Rho Kinase (ROCK) inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, media was changed and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and beacon placement at the B2M locus and/or the CIITA locus was measured using ddPCR and/or AmpSeq. [0607] FIGs. 10A-10B show beacon placement in iPSC lines ACS-1030 (iPSC1) and ACS- 1026 (iPSC2) at B2M exon 1 and/or CIITA exon 2 for each iPSC line. FIG.10A (left panel) shows beacon placement in iPSC line 1 (ACS-1030) at the B2M locus was between about 15% to about 95% as measured by ddPCR and between about 30% to about 95% as measured by AmpSeq. Additionally, FIG.10A shows beacon placement in iPSC line 1 (ACS-1030) at the CIITA locus was between about 25% to about 45% as measured by ddPCR and between about 30% to about 55% as measured by AmpSeq. FIG.10B shows beacon placement in iPSC line 2 (ACS-1026) at the B2M locus was between about 10% to about 75% as measured by ddPCR. FIG. 10B also shows beacon placement in iPSC line 2 (ACS-1026) at the CIITA locus was between about 10% to about 15% as measured by ddPCR. [0608] Overall, this data showed efficient beacon placement in iPSCs at both the B2M and CIITA loci. 8.3. Example 2: Concurrent beacon placement at B2M and CIITA loci in iPSCs using a dual atgRNA approach at each locus [0609] To demonstrate and optimize concurrent attB beacon placement (i.e., integration recognition site placement or incorporation) at the B2M and CIITA loci within an iPSC, a dual atgRNA approach to beacon placement was used for beacon placement at each locus. The same dual atgRNAs as described in Example 1 were used in this Example. A non-limiting example of a method of generating an iPSC where the method includes concurrent site-specific integration of integration recognition sites in the B2M locus and CIITA locus is shown in FIG.8. [0610] iPSC lines ACS-1030 (iPSC1) and ACS-1026 (iPSC2) were cultured as undifferentiated iPSCs on Cell Basement Membrane (ATCC)-coated plates in Pluripotent Stem Cell SFM XF/FF media (ATCC). Undifferentiated iPSCs were electroporated with prime editor fusion protein (2 micrograms mRNA encoding prime editor fusion protein) and atgRNA (50 picomoles). Electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK-inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, media was changed, and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and beacon placement at the B2M locus and/or the CIITA locus was measured using ddPCR and/or AmpSeq. [0611] FIGs.11A-11B shows concurrent beacon placement at B2M and CIITA loci using the dual atgRNA approach for beacon placement at each locus as described above. FIG.11A shows ddPCR plots, with the top panel showing data for target specific probes and the bottom panel showing data for control probes. FIG. 11B shows a summary histogram from the ddPCR data presented in the FIG.11A. [0612] Overall, FIGs. 11A-11B show successful concurrent beacon placement at B2M and CIITA loci with at least 84.9% beacon placement for B2M and at least 51.3% beacon placement for CIITA. [0613] For iPS cell line generation, electroporated iPSCs were plated on Cell Basement Membrane-coated plates in Pluripotent Stem Cell SFM XF/FF media and allowed to recover. iPSCs were plated at a density suitable to allow the single cells to grow into iPSC colonies that could be picked and expanded for purposes of cell line generation. During initial colony expansion (i.e., prior to picking), iPSCs were grown in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632. About 7-14 days following plating, colonies were picked, disassociated into clumps (e.g., no less than 4 cells per clump) and re-plated onto a Cell Basement Membrane-coated dish. The picked iPSC lines were expanded, analyzed for beacon placement, and cryopreserved. [0614] Analysis of beacon placement in the iPSC lines generated according to the methods described above is shown in FIGs. 12A-12B. FIG. 12A shows raw ddPCR data for beacon placement at the B2M locus and the CIITA locus for 22 iPSC lines. FIG. 12B is a histogram summarizing ddPCR data for three iPSC lines: line 1, line 8, and line 9. Line 1 and line 9 show 100% bi-allelic beacon placement at both B2M and CIITA loci. AmpSeq was used to confirm the ddPCR data. FIG.13 shows AmpSeq data for 6 iPSC lines including lines 1, 8, 9, 16, 17, and 22. The AmpSeq data did indeed confirm the ddPCR data from FIGs. 12A-12B. Based on the data from FIGs.12A-12B and FIG.13, iPSC lines 16, 17 and 22 showed concurrent, bi-allelic beacon placement at both B2M and CIITA loci. Therefore, these lines were selected for programmable gene insertion (i.e., integration of donor polynucleotide templates) into one or both of the B2M locus and the CIITA locus. 8.4. Example 3: Concurrent Integration of 6 kilobase donor templates at beacons incorporated into the B2M and CIITA loci using electroporation [0615] The iPS cell lines generated in Example 2 were used to assess concurrent integration integrate donor polynucleotide templates at the B2M locus, the CIITA locus, or both. In this Example, a first donor polynucleotide template (pDY-GG-EF1aGFP (SEQ ID NO: 618) about 6 kilobase (kb) in size having an AttP integration recognition site comprising a GG central dinucleotide was targeted to the AttB integration recognition site that was site-specifically integrated at the B2M locus. This Example also included a second donor polynucleotide template (pL1113 (SEQ ID NO: 619) about 5 kb in size having an AttP integration recognition site comprising a GT central dinucleotide that was targeted to the AttB integration recognition site site- specifically integrated at the CIITA locus. [0616] At Day 0, the undifferentiated iPS cell line (line #17) was electroporated with plasmid DNA encoding BxB1 as well as plasmid DNA from the first donor polynucleotide template and/or plasmid DNA from the second donor polynucleotide template. In particular, a single cell suspension of 100,000 iPSCs in 10 µL E1 buffer was combined with plasmid DNA according to the conditions specified in the Table 14.

[0617] Electroporation was performed using a Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, the media was refreshed without Y27632 and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and beacon placement at the B2M locus and/or the CIITA locus was measured using ddPCR and/or AmpSeq. [0618] FIGs.14A-B illustrates the primer and probe design for detecting integration of donor polynucleotide templates at the B2M locus (FIG. 14A) and the CIITA locus (FIG. 14B) using ddPCR. [0619] FIG.15 shows integration of the first donor polynucleotide template at the B2M locus (site 1) and the second donor polynucleotide template at the CIITA locus (site 2) as determined by ddPCR. In particular, FIG. 15 shows successful integration of the first donor polynucleotide template at the B2M locus (site 1) in both the single and duplex conditions. FIG.15 also illustrates successful integration of the second donor polynucleotide template at the CIITA locus (site 2) in both the single and duplex conditions. In the first “single” condition, integration of the first donor polynucleotide template at the B2M locus (site 1) occurred at about 1% of the B2M locus (see FIG. 15). In the other “single” condition, integration of the second donor polynucleotide template at the CIITA locus (site 2) occurred at about 9% of the CIITA loci (see FIG.15). [0620] In the duplex condition, integration of the first donor polynucleotide templates into the B2M locus (site 1) occurred in about 1.5% of the B2M locus and integration of the second donor polynucleotide template into the CIITA locus occurred at about 14% of the CIITA locus. [0621] Overall, this data showed the ability to concurrently integrate the first and second donor polynucleotides in an iPSC line in a single transduction. 8.5. Example 4: Integration of 31 kilobase adenovirus donor template within beacons incorporated into the CIITA locus in an iPSC [0622] The iPS cell lines generated in Example 2 were used to test integration of a 31 kilobase (kb) donor polynucleotide template at the CIITA locus. In particular, the donor polynucleotide template was a 31kb adenoviral vector (SEQ ID NO: 667) containing an AttP integration recognition site comprising a GG central dinucleotide that was integrated to the AttB integration recognition site site-specifically integrated at exon 2 of the CIITA locus. The adenoviral donor template was introduced into the iPSCs as an adenovirus. [0623] Adenovirus production was performed as described in Ioannidi et al. (bioRxiv 2021.11.01.466786; doi.org/10.1101/2021.11.01.466786) and Wold et al. (Curr. Gene Ther.13, 421–433 (2013)), each of which are herein incorporated by reference in its entireties. [0624] At Day 0, the undifferentiated iPS cell line (line #17) was electroporated with plasmid DNA encoding BxB1. In particular, a single cell suspension of 100,000 iPSCs in 10 µL E1 buffer was combined with 0.5 µg of plasmid DNA encoding BxB1. Electroporation was performed using a Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 0 µM ROCK inhibitor Y27632 and allowed to recover for about 24 hours. [0625] Following the 24-hour recovery period, the electroporated iPSCs were contacted with adenovirus containing the donor polynucleotide template. Various multiplicity of infections (MOIs), including MOIs of 0.01, 0.1, 1, and 10, were used to infect the cells. The different MOIs helped assess dose-dependent impacts on infection and integration. [0626] Following adenovirus infection, iPSCs were cultured for an additional two days prior to harvesting the cells and analyzing for integration of the donor polynucleotide templates. DNA was harvested using a LGC QuickExtract buffer and integration of donor polynucleotide template at the CIITA locus was measured using ddPCR. As noted above, FIG.14B shows a schematic of the primer and probe design for the ddPCR assay used to detect integration of the 31kb donor polynucleotide template at the CIITA locus. [0627] As shown in FIG.16, the 31kb donor polynucleotide template integrated into the CIITA locus in a dose-dependent manner. At an MOI of 10, the 31kb donor polynucleotide integrated into the CIITA locus occurred in about 6% of the CIITA locus. [0628] Overall, this data demonstrates the ability to site-specifically incorporate integration recognition sites into the genome of an iPSC and use these sites along with an integrase to integrate a 31kb donor polynucleotide template at the integration recognition sites. 8.6. Example 5: Beacon placement at CD52 locus in iPSCs having beacons in B2M and CIITA loci [0629] A dual atgRNA approach was used for beacon (also referred to as an integration recognition site) placement at the CD52 locus. A non-limiting example of a method of generating an iPSC where the method includes placing a beacon in the CD52 locus in an iPSC line already having beacons in the B2M and CIITA loci is shown in FIG.8. AtgRNA used in this Example are shown in Table 15. To knockout CD52 expression and place a beacon in the CD52 locus, three forward atgRNAs and four reverse atgRNA all within the 200bp of CD52 exon 1 were designed. After identifying these atgRNAs, forward and reverse atgRNA were combined to make 12 combinations of dual atgRNAs pairs (see Table 15 and FIG.19A).

[0630] Each of these twelve atgRNA pairs were individually electroporated along with a mRNA encoding a gene editor polypeptide (e.g., a Cas9n-RT) into iPSC clone #17 (see FIG.19A for atgRNA pairs). For the electroporation, 3.0 µg of an mRNA encoding the gene editor polypeptide and 0.5 µL (50pmol) of each of the atgRNA RNAF and atgRNA R were added to 100,000 cells of iPS clone #17. Electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Clone #17 has perfect beacon placement in both B2M and CIITA loci. After electroporation, genomic DNA was isolated and ddPCR was performed using primers and proved designed to detect beacon placement within the 200bp of CD52 exon 1 (see Table 13). As shown in FIG. 19A, ddPCR analysis revealed the highest performing atgRNA pair, which was pair 6, resulted in 39% beacon placement. Other top performing atgRNA pairs included pairs 2, 5, and 8, each having beacon placement higher than 30% (see FIG.19A). The highest performing pairs (i.e., pairs 2, 5, 6 and 8 (~30% BP)) were used for placing a beacon in the CD52 locus. Cells electroporated with pairs 2, 6, and 8 were subjected to next generation sequencing as an alternative means for detecting beacon placement. As shown in FIG.19B, NGS analysis confirmed that pairs 2, 6, and 8 produced the highest beacon placement, and in fact had higher beacon placement percentages than were detected from ddPCR analysis. [0631] To increase percent beacon placement, atgRNA were designed to target additional regions of CD52. CD52 is a small protein with only two exons, so additional guide atgRNAs are being designed and tested that target exon1-intron 1 junction, intron1-exon2 junction and exon 2. Similar to the atgRNA targeting CD52 exon 1, the atgRNA are designed such that they knockout expression of CD52 while also placing a beacon to be used for programmable gene insertion. In particular, the atgRNA designed to target the intron1-exon2 junction were designed to delete the coding sequence upstream of serine 36. CD52 has 61 amino acids where amino acids 1-24 are the signal peptide and amino acids 37-61 of the propeptide are cleaved . Therefore, as long as placing the beacon removes the first 35 amino acid residues of CD52 it will lose function. [0632] For additional studies, including generating an iPSC line starting with iPSC clone #17 such that the resulting line has beacons in (and knockout of) CD52, B2M, and CIITA, atgRNA pair six was selected to place the beacon in the CD52 locus. In particular, for iPSC line generation, iPSC line #17 was electroporated with an mRNA encoding the gene editor polypeptide and a pair of atgRNA that enable beacon placement (and subsequent knock out of) in the CD52 locus. Electroporated iPSCs were plated on Cell Basement Membrane-coated plates in Pluripotent Stem Cell SFM XF/FF media and allowed to recover. iPSCs were plated at a density suitable to allow the single cells to grow into iPSC colonies that could be picked and expanded for purposes of cell line generation. During initial colony expansion (i.e., prior to picking), iPSCs were grown in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632. About 7-14 days following plating, colonies were picked, disassociated into clumps (e.g., no less than 4 cells per clump) and re-plated onto a Cell Basement Membrane-coated dish. The picked iPSC lines were expanded, analyzed for beacon placement, and cryopreserved. 8.7. Example 6: Beacon placement at CISH locus in iPSCs having beacons in B2M and CIITA loci [0633] A dual atgRNA approach was used for beacon (also referred to as an integration recognition site) placement at the CISH locus. A non-limiting example of a method of generating an iPSC where the method includes placing a beacon in the CISH locus in an iPSC line already having beacons in each of the B2M and CIITA loci is shown in FIG. 8. AtgRNA used in this Example are shown in Table 16. To knockout CISH and place a beacon in the CISH locus, six pairs of atgRNAs were designed that targeted exon 1 and exon 2 in the CISH locus. After identifying these atgRNAs, forward and reverse atgRNA were combined to make the six atgRNA pairs (see Table 16 and FIGs.20A-20B).

[0634] The six pairs of atgRNA were electroporated along with a mRNA encoding a gene editor polypeptide (e.g., a Cas9n-RT) into iPSC clone #17. For the electroporation, 3.0 µg of an mRNA encoding the gene editor polypeptide and 0.5 µL (50pmol) of each of the atgRNA RNAF and atgRNA R were added to 100,000 cells of iPSC clone #17. Electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. As described herein, clone #17 has perfect beacon placement at both the B2M and the CIITA loci. After electroporation, genomic DNA was isolated and ddPCR was performed using primers and probes designed to detect beacon placement at the CISH locus (see Table 13). As shown in FIG. 20A, ddPCR analysis revealed the highest performing atgRNA pair produced about 61% percent beacon placement. gDNA from cells electroporated with the two highest performing atgRNA pairs were kept for NGS analysis to further characterize perfect beacon placement. Cells electroporated in FIG.20A were also subjected to next generation sequencing as an alternative means for detecting beacon placement. FIG. 20B, which shows the NGS analysis, confirmed the same pattern of beacon placement efficiency shown in FIG.20A. [0635] For additional studies, including generating an iPSC line starting with iPSC clone #17 such that the resulting line has beacons in (and knockout of) B2M, CIITA, and CISH, the top performing atgRNA pair (SP01-N01, see FIG. 20A) was electroporated into iPSC line #17. In particular, for iPSC line generation, iPSC line #17 was electroporated with an mRNA encoding the gene editor polypeptide and a pair of atgRNA that enable beacon placement (and subsequent knock out of) in the CISH locus. Electroporated iPSCs were plated on Cell Basement Membrane- coated plates in Pluripotent Stem Cell SFM XF/FF media and allowed to recover. iPSCs were plated at a density suitable to allow the single cells to grow into iPSC colonies that could be picked and expanded for purposes of cell line generation. During initial colony expansion (i.e., prior to picking), iPSCs were grown in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632. About 7-14 days following plating, colonies were picked, disassociated into clumps (e.g., no less than 4 cells per clump) and re-plated onto a Cell Basement Membrane-coated dish. The picked iPSC lines were expanded, analyzed for beacon placement, and cryopreserved. 8.8. Example 7: Beacon placemen at ADORA2A locus in iPSC having beacons in B2M and CIITA loci [0636] A dual atgRNA approach was used for beacon placement at the ADORA2A locus. A non-limiting example of a method of generating an iPSC where the method includes placing a beacon in the ADORA2A locus in an iPSC line already having beacons in the B2M and CIITA loci is shown in FIG.8. AtgRNA used in this Example are shown in Table 17. To knockout expression of ADORA2A and place a beacon in the ADORA2A locus, five atgRNA pairs were designed that targeted exon 2 of the ADOR2A2 locus. Forward and reverse atgRNA were combined to make the five atgRNA pairs that were tested in this example (see Table 17 and FIGs.21A-21B).

[0637] The five pairs of atgRNA were electroporated along with a mRNA encoding a gene editor polypeptide (e.g., a Cas9n-RT) into iPSC clone #17. For the electroporation, 3.0 µg of an mRNA encoding the gene editor polypeptide and 0.5 µL (50pmol) of each of the atgRNA RNAF and atgRNA R were added to 100,000 cells of iPS clone #17. Electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. After electroporation, genomic DNA was isolated and ddPCR was performed using primers and probes designed to detect beacon placement at the ADOR2A2 locus (see Table 13). As shown in FIG. 21A, ddPCR analysis revealed the highest performing atgRNA produced about 58% percent beacon placement. Cells electroporated in FIG. 21A were also subjected to next generation sequencing as an alternative means for detecting beacon placement. FIG.21B, which shows the NGS analysis, confirmed the same pattern of beacon placement efficiency shown in FIG.21A. [0638] For additional studies, including generating an iPSC line starting with iPSC clone #17 such that the resulting line has beacons in (and knockout of) ADORA2A, B2M, and CIITA, the top performing atgRNA pair (SP01-N01, see FIG. 21A) was electroporated into iPSC line #17. In particular, for iPSC line generation, iPSC line #17 was electroporated with an mRNA encoding the gene editor polypeptide and a pair of atgRNA that enable beacon placement (and subsequent knock out of) in the ADORA2A locus. Electroporated iPSCs were plated on Cell Basement Membrane-coated plates in Pluripotent Stem Cell SFM XF/FF media and allowed to recover. iPSCs were plated at a density suitable to allow the single cells to grow into iPSC colonies that could be picked and expanded for purposes of cell line generation. During initial colony expansion (i.e., prior to picking), iPSCs were grown in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632. About 7-14 days following plating, colonies were picked, disassociated into clumps (e.g., no less than 4 cells per clump) and re-plated onto a Cell Basement Membrane-coated dish. The picked iPSC lines were expanded, analyzed for beacon placement, and cryopreserved. 8.9. Example 8: Concurrent beacon placement at B2M, CIITA, and CD52 loci in iPSCs using a dual atgRNA approach at each locus [0639] To demonstrate and optimize concurrent attB beacon placement (i.e., integration recognition site placement or incorporation) at the B2M, CIITA, and CD52 loci within an iPSC, a dual atgRNA approach to beacon placement was used for beacon placement at each locus. The same dual atgRNAs as described in Example 1 (B2M and CIITA atgRNAs) and Example 5 (CD52 atgRNAs) were used in this Example. A non-limiting example of a method of generating an iPSC where the method includes concurrent site-specific integration of integration recognition sites in the B2M locus, the CIITA locus, and the CD52 locus is shown in FIG.8. [0640] iPSC lines ACS-1030 (iPSC1) and ACS-1026 (iPSC2) were cultured as undifferentiated iPSCs on Cell Basement Membrane (ATCC)-coated plates in Pluripotent Stem Cell SFM XF/FF media (ATCC). Undifferentiated iPSCs were electroporated with 2 µg mRNA encoding a gene editor polypeptide (Cas9n-RT) and 50 picomoles of each atgRNA as described in Table 18.

[0641] To test if we can achieve similar efficiency of triple beacon placement to single beacon placement, we did single and triple beacon placement side by side. For single beacon placement (sample 2 to 6), PE2 mRNA and single pair atgRNA of B2M (B2M bmp001 or bmp003), CIITA (CIITA bmp001 or bmp003) or CD52 mod2 were electroporated into WT iPSC2. For triple (3x) beacon placement (sample 7-9), PE2 mRNA plus B2M bmp001, CIITA bpm001 and CD52 mod2 atgRNA pairs were electroporated into WT iPSC2. For triple (3x) beacon placement (sample 10- 12), PE2 mRNA plus B2M bmp003, CIITA bmp003 and CD52 mod2 atgRNA pairs were electroporated into WT iPSC2 cells. [0642] Electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK-inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, media was changed and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and beacon placement at the B2M locus and/or the CIITA locus was measured using ddPCR. Cells were harvested 72 hours post electroporation and subjected to ddPCR analysis. [0643] FIG. 22 shows ddPCR data of percent beacon placement. The ddPCR data revealed that the beacon placement efficiency is comparable between triple and single beacon placement (see FIG.22). For B2M the efficiency was about 80%, for CIITA the efficiency was between 10- 20%, and for CD52 the efficiency was about 50%. [0644] Overall, this data showed concurrent beacon placement in three different target loci (i.e., B2M, CIITA, and CD52 loci) following a single transfection in wild type iPSC. 8.10. Example 9: Concurrent beacon placement at the TRAC and the AAVS1 loci using a dual atgRNA approach at each locus [0645] To demonstrate and optimize concurrent attB beacon placement (i.e., integration recognition site placement or incorporation) at the TRAC and AAVS1 loci in iPSC clone 17 (i.e., an iPSC clone having beacons already placed at the B2M and CIITA loci), a dual atgRNA approach to beacon placement was used for beacon placement at each locus. AtgRNAs for targeting the TRAC and AAVS1 loci are as described in Table 19. A non-limiting example of a method of generating an iPSC where the method includes concurrent site-specific integration of integration recognition sites in the B2M locus, the CIITA locus, the TRAC locus, and the AAVS1 locus is shown in FIG.8.

[0646] iPSC lines 16, 17, and 29 were cultured as undifferentiated iPSCs on Cell Basement Membrane (ATCC)-coated plates in Pluripotent Stem Cell SFM XF/FF media (ATCC). Undifferentiated iPSCs were electroporated with 2 µg mRNA encoding a gene editor polypeptide (Cas9n-RT) and 50 picomoles of each atgRNA. [0647] Electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK-inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, media was changed and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and beacon placement at the B2M locus and/or the CIITA locus was measured using ddPCR and/or AmpSeq. [0648] FIG. 23 shows concurrent beacon placement at the TRAC and AAVS1 loci in iPSC clone 17. In particular, FIG. 23 shows ddPCR data of percent beacon placement with the respective pairs with nearly 100% beacon placement at AAVS1, and around 30% beacon placement at TRAC. [0649] Overall, this data demonstrated successful generation of a cell line comprising four beacons placed at four different loci in the genome. 8.11. Example 10: iPSC line generation of iPSC containing beacons in B2M, CIITA, TRAC and AAVS1 loci [0650] To generate iPSC lines having attB beacons (i.e., integration recognition sites) at the TRAC and AAVS1 loci, iPSC line #17, which has a beacon already placed in both the B2M and CIITA loci, was electroporated with dual atgRNAs targeting the TRAC and AAVS1 are described in the preceding examples. A non-limiting example of a method of generating an iPSC cell line where the method includes concurrent site-specific integration of integration recognition sites (beacons) in one or more of the B2M locus, the CIITA locus, the TRAC locus, and the AAVS1 locus is shown in FIG.24. [0651] For these experiments, iPSC clone # 17 was cultured as undifferentiated iPSCs on Cell Basement Membrane (ATCC)-coated plates in Pluripotent Stem Cell SFM XF/FF media (ATCC). Undifferentiated iPSCs were electroporated with 2 µg mRNA encoding a gene editor polypeptide (Cas9n-RT) and atgRNA as described in Examples 2 and 9. In particular, electroporation was performed using the Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK-inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, media was changed and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and beacon placement at the B2M locus and/or the CIITA locus was measured using ddPCR and/or AmpSeq. As shown in FIG. 24 and FIG. 25, multiple lines were selected and expanded, including iPSC clones 16, 26, 27, 29, 30, and 33. [0652] FIG.25 shows next generation sequencing data for beacon placement at the TRAC and AAVS1 loci in the indicated iPSC lines. Overall, this data demonstrated successful generation of a cells comprising four beacons placed at four different loci in the genome. From this data, iPSC lines containing beacons in each the B2M, CIITA, TRAC, and AAVS1 loci were used for multiplexed programmable gene insertion (i.e., concurrent site-specific integration of four donor polynucleotide templates). 8.12. Example 11: Concurrent site-specific integration of four donor templates in iPS cells containing beacons at B2M, CIITA, TRAC, and AAVS1 loci [0653] iPS cells generated in Example 10 containing beacons at each of the B2M, CIITA, TRAC, and AAVS1 loci were used to assess concurrent integration of donor polynucleotide templates at each of the locus (also referred to as multiplexed programmable gene insertion). Each of the four donor polynucleotide templates included a beacon (i.e., an integration recognition site (e.g., an AttP site)) comprising a different central dinucleotide than the beacons in the other donor polynucleotide templates. Each beacon in each donor polynucleotide template was “paired” with its corresponding (cognate) integration recognition site site-specifically integrated into the iPSC genome at one of the B2M, CIITA, TRAC, and AAVS1 loci (see lines generated in Example 10), such that when contacted with an integration enzyme a recombination event occurs and integration results. [0654] As described in Example 3, a first donor polynucleotide template (pDY-GG-EF1aGFP (SEQ ID NO: 618)) about 6 kilobase (kb) in size and having an AttP integration recognition site comprising a GG central dinucleotide was targeted to the AttB integration recognition site that was site-specifically integrated at the B2M locus. The second donor polynucleotide template (pL1113 (SEQ ID NO: 619)) was about 5 kb in size and included an AttP integration recognition site comprising a GT central dinucleotide that was targeted to the AttB integration recognition site site- specifically integrated at the CIITA locus. The third donor polynucleotide template (pL1220 (SEQ ID NO: 620)) was about 3.8 kb in size and included an AttP integration recognition site comprising a CT central dinucleotide that was targeted to the AttB integration recognition site site-specifically integrated at the TRAC locus. The fourth donor polynucleotide template (pL1218 (SEQ ID NO: 621)) was about 4.0 kb in size and included an AttP integration recognition site comprising an AC central dinucleotide that was targeted to the attB integration recognition site site-specifically integrated at the AAVS1 locus. Sequences of each the donor polynucleotide templates used for multiplexed programmable gene insertion are described in Table 20.

[0655] In a first set of experiments, about 0.8µg of each donor polynucleotide template (about 3.2 µg total) were combined with about 1.0 µg of a plasmid PL193 encoding a BxB1 polypeptide. The final volume was brought to 6 µL and combined with about 100,000 cells of iPSC clones #16 or clone #29 in 10 µL E1 buffer. Similar to clone #17, clones #16 and #29 each have beacons integrated at the B2M, CIITA, TRAC, and AAVS1 loci. The cells-plasmid mixture was electroporated using a Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, the media was refreshed without Y27632 and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and integration of the donor polynucleotides at each locus was measured using ddPCR and/or AmpSeq. [0656] As shown in FIG.26, concurrent integration of the donor polynucleotide templates at each of the four loci was observed in both iPSC clones #16 and #29. Notably, the efficiency was consistent in both colonies. The highest PGI being at the TRAC locus for both clones, with #29 having only 1% greater PGI than #16. [0657] In a third set of experiments, about 1.0µg of each donor polynucleotide template (about 3.2 µg total) were combined with about 2.0 µg of a mRNA (PL 1325) encoding a BxB1 polypeptide. The final volume was brought to 6 µL and combined with about 100,000 cells of iPSC clones #30 in 10 µL E1 buffer. Similar to clone #17, clone #30 has beacons integrated at the B2M, CIITA, TRAC, and AAVS1 loci. The cells-plasmid mixture was electroporated using a Neon Transfection System with a Neon P10 tip at 1200V, 30 msec, 1 pulse. Following electroporation, the electroporated iPSCs were plated on Cell Basement Membrane coated 48 well plates in Pluripotent Stem Cell SFM XF/FF media supplemented with 10 µM ROCK inhibitor Y27632 and allowed to recover for about 24 hours. After 24 hours, the media was refreshed without Y27632 and cells were cultured for an additional 72 hours. DNA was harvested using LGC QuickExtract buffer and integration of the donor polynucleotides at each locus was measured using ddPCR and/or AmpSeq. As shown in FIG. 27, concurrent integration of the donor polynucleotide templates at each of the four loci was observed in iPSC clone #30. [0658] Overall, this data represents the first successful demonstration of multiplexed PGI at four different loci. 9.
