ACKNOWLEDGMENT OF GOVERNMENT SUPPORT This invention was made with government support under grant numbers NR016436 and GM063569 awarded by the National Institutes of Health, and Merit Award ONCA-019-18F awarded by the Department of Veterans Affairs. The government has certain rights in the invention. INCORPORATION OF ELECTRONIC SEQUENCE LISTING The electronic sequence listing, submitted herewith as an XML file named 8123-107870-02.xml (39,990 bytes), created on March 16, 2023, is herein incorporated by reference in its entirety. BACKGROUND Cutaneous wound healing is a dynamic and well-organized series of overlapping phases of repair that culminates in forming newly intact dermal and epidermal tissue layers. Pathological ailments such as diabetes and vascular disease obstruct the early phases of the wound healing process and result in the formation of a chronic wound. Wounds become considered chronic when they fail to close after three months post incident. One of the primary complications that lead to chronic wounds is disruptions to the blood supply. Rapid generation of new vasculature is necessary early within the wound healing process to deliver nutrients and oxygen, remove cellular and extracellular debris, and help with the transportation of cells into and out of the wound micro-environment. SUMMARY Controlled delivery methods and compositions that enhance wound healing (such as wound closure) and reduce fibrotic scarring are described. Specifically provided are methods of treating a wound, such as a dermal wound or a mucosal wound, in a subject by administering to the subject a therapeutically effective amount of a first agent that promotes wound closure and a therapeutically effective amount of a second agent that inhibits scarring. ^{8123-107870-02} In some aspects, the first agent is administered to the subject prior to administration of the second agent, for example 1 day to 3 weeks prior to administration of the second agent. In other aspects, the first agent and the second agent are administered concurrently in a controlled delivery composition that permits rapid release of the first agent and delayed release of the second agent. In some examples, the controlled delivery composition includes a hydrogel, and the hydrogel includes (i) the first agent, and (ii) the second agent which is encapsulated in a coacervate, such that upon administration of the controlled delivery composition, the first agent is released from the hydrogel at a faster rate than the second agent is released from the coacervate. In other examples, the controlled delivery composition includes a first coacervate that includes the first agent; a second coacervate that includes the second agent, wherein the second coacervate is encapsulated by lipids, thereby forming a lipo-coacervate, such that upon administration of the controlled delivery composition, the first agent is released from the first coacervate prior to release of the second agent from the lipo-coacervate. In other examples, the controlled delivery composition includes a first coacervate that includes the first agent, wherein the first coacervate is encapsulated by lipids, thereby forming a first lipo-coacervate; and a second coacervate that includes the second agent, wherein the second coacervate is encapsulated by lipids, thereby forming a second lipo- coacervate, such that upon administration of the controlled delivery composition, the first agent is released from the first lipo-coacervate prior to release of the second agent from the second lipo-coacervate. Also provided are controlled delivery compositions for treating a wound that include a therapeutically effective amount of a first agent that promotes wound closure and a therapeutically effective amount of a second agent that inhibits scarring, such that the controlled delivery compositions permit rapid release of the first agent and delayed release of the second agent. In some aspects, the controlled delivery composition includes a hydrogel, wherein the hydrogel includes the first agent and the second agent encapsulated in a coacervate, such that upon administration of the controlled delivery composition, the first agent is released from the hydrogel prior to release of the second agent from the coacervate. In other aspects, the controlled delivery composition includes a first coacervate that includes the first agent, a second coacervate that includes the second agent, wherein the second coacervate is encapsulated by lipids, thereby forming a lipo-coacervate, such that upon administration of the controlled delivery composition, the first agent is released from the first coacervate prior to release of the second agent from the lipo-coacervate. In other aspects, the controlled delivery composition includes a first coacervate that includes the first agent, wherein the first coacervate is encapsulated by lipids, thereby forming a first lipo-coacervate; and a second coacervate that includes the second agent, wherein the second coacervate is encapsulated by lipids, thereby forming a second lipo-coacervate, such that upon administration of the controlled delivery composition, the first agent is released from the first lipo-coacervate prior to release of the second agent from the second lipo-coacervate. ^{8123-107870-02} The foregoing and other features of this disclosure will become more apparent from the following detailed description of several aspects which proceeds with reference to the accompanying figures.

Terms and Methods Unless otherwise noted, technical terms are used according to conventional usage. Definitions of many common terms in molecular biology may be found in Krebs et al. (eds.), Lewin’s genes XII, published by Jones & Bartlett Learning, 2017. As used herein, the singular forms “a,” “an,” and “the,” refer to both the singular as well as plural, unless the context clearly indicates otherwise. For example, the term “an antigen” includes singular or plural antigens and can be considered equivalent to the phrase “at least one antigen.” As used herein, the term “comprises” means “includes.” It is further to be understood that any and all base sizes or amino acid sizes, and all molecular weight or molecular mass values, given for nucleic acids or polypeptides are approximate, and are provided for descriptive purposes, unless otherwise indicated. Although many methods and materials similar or equivalent to those described herein can be used, particular suitable methods and materials are described herein. In case of conflict, the present specification, including explanations of terms, will control. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting. To facilitate review of the various aspects, the following explanations of terms are provided: Administration: The introduction of a composition (such as a controlled delivery composition disclosed herein) to a subject by a chosen route. Exemplary routes of administration for the agents and compositions disclosed herein include, but are not limited to, topical (including on a wound dressing, such as a single-use bandage), transdermal, oral, sublingual, injection (such as subcutaneous or intradermal injection), intranasal, inhalation and via a medical implant. As used herein, “administered concurrently” means administered at the same time (including in the same composition or in separate compositions) or during the same session. Amphiregulin (AREG): A member of the epidermal growth factor family. The AREG protein is an autocrine growth factor as well as a mitogen for astrocytes, Schwann cells and fibroblasts. It is related to epidermal growth factor (EGF) and transforming growth factor alpha (TGF-alpha). The protein interacts with the EGF/TGF-alpha receptor to promote the growth of normal epithelial cells, and it inhibits the growth of certain aggressive carcinoma cell lines. AREG also functions in mammary gland, oocyte and bone tissue development. The AREG gene is associated with a psoriasis-like skin phenotype, and is also associated with other pathological disorders, including various types of cancers and inflammatory conditions. Nucleic acid and amino acid sequences for human AREG (and homologs thereof) are publicly available, such as under NCBI Gene ID 374. Angiogenesis: The physiological process involving the growth of new blood vessels from pre- existing vessels. Angiogenesis is a normal and vital process in growth and development, as well as in wound healing. C-X-C chemokine receptor 3 (CXCR3): A G protein-coupled receptor with selectivity for four chemokines, CXCL4/PF4 (platelet factor 4), CXCL9/Mig (monokine induced by interferon-γ), CXCL10/IP- 10 (interferon-γ-inducible 10 kDa protein) and CXCL11/I-TAC (interferon-inducible T cell a- chemoattractant). Binding of chemokines to this protein induces cellular responses that are involved in ^{8123-107870-02} leukocyte trafficking, most notably integrin activation, cytoskeletal changes and chemotactic migration. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Chemokine (C-X-C motif) ligand 4 (CXCL4): A small cytokine belonging to the CXC chemokine family. CXCR4, also known as platelet factor 4 (PF4), is a 70-amino acid protein that is released from the alpha-granules of activated platelets and binds with high affinity to heparin. Its primary physiologic role is neutralization of heparin-like molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, CXCL4 is believed to play a role in inflammation and wound repair. CXCL4 binds the B isoform of CXCR3 (CXCR3-B). Sequences for CXCL4 are publicly available (see, for example, GENBANK^TM Gene ID 5196). Exemplary human CXCL4 nucleic acid and protein sequence are set forth herein as SEQ ID NOs: 13 and 14, respectively. Chemokine (C-X-C motif) ligand 9 (CXCL9): A member of the CXC chemokine family. The CXCL9 protein is thought to be involved in T cell trafficking. CXCL9 binds to CXCR3 and is a chemoattractant for lymphocytes, but not for neutrophils. Nucleic acid and amino acid sequences for human CXCL9 (and homologs thereof) are publicly available, such as under NCBI Gene ID 4283. Exemplary human CXCL9 nucleic acid and protein sequence are set forth herein as SEQ ID NOs: 7 and 8, respectively. Chemokine (C-X-C motif) ligand 10 (CXCL10): A chemokine of the CXC subfamily and a ligand for the receptor CXCR3. CXCL10 is also known as interferon-γ-inducible 10 kDa protein (IP-10). Binding of this protein to CXCR3 results in pleiotropic effects, including stimulation of monocytes, natural killer and T-cell migration, modulation of adhesion molecule expression, and inhibition of vessel formation. CXCL10 nucleic acid and amino acid sequences are publicly available, such as under NCBI Gene ID 3627 (see also GENBANK^TM Accession No. P02778). Exemplary human CXCL10 nucleic acid and protein sequence are set forth herein as SEQ ID NOs: 9 and 10, respectively. Chemokine (C-X-C motif) ligand 11 (CXCL11): A chemokine of the CXC subfamily and a ligand for the receptor CXCR3. The CXCL11 protein induces a chemotactic response in activated T-cells and is the dominant ligand for CXCR3. The CXCR11 gene contains 4 exons and at least three polyadenylation signals which may reflect cell-specific regulation of expression. IFN-γ is a potent inducer of transcription of this gene. Nucleic acid and amino acid sequences for CXCL11 are publicly available, such as under NCBI Gene ID 6373. Exemplary human CXCL11 nucleic acid and protein sequence are set forth herein as SEQ ID NOs: 11 and 12, respectively. Cholesterol: A type of lipid molecule classified as a sterol. Cholesterol is an important structural component of biological membranes. The chemical formula for cholesterol is C₂₇H₄₆O and the IUPAC ID for cholesterol is (3β)-cholest-5-en-3-ol (see also PubChem CID 5997). Coacervate: Spherical aggregates of colloidal droplets held together (and apart from their surrounding liquid environment) by hydrophobic forces. Coacervate droplets are generally about 0.1 to about 100 µm in diameter. Coacervates typically aggregate over time to form a bulk phase separation from the aqueous compartment. Coacervates can be used as controlled delivery vehicles for small molecules and ^{8123-107870-02} protein therapeutics. Advantageous features of a coacervate for drug delivery include their high loading capacity and ability to self-assemble in aqueous media (see, e.g., Johnson and Wang, Expert Opin Drug Deliv 11(12):1829-1832, 2014). In some aspects herein, the coacervate includes a positively charged synthetic biodegradable poly(ethylene arginyl aspartate diglyceride) (PEAD) and a negatively charged heparin, which forms a 3-dimensional coacervate that envelopes around the protein cargo to be administered. Other coacervates can be used, such as those described in U.S. Patent Application Publication Nos.2019/0117780 and 2021/0290770. Collagen type I alpha 1 chain (COL1A1): A gene encoding the pro-alpha1 chains of type I collagen whose triple helix comprises two alpha1 chains and one alpha2 chain. Type I is a fibril-forming collagen found in most connective tissues and is abundant in bone, cornea, dermis and tendon. Mutations in the COL1A1 gene are associated with osteogenesis imperfecta types I-IV, Ehlers-Danlos syndrome type VIIA, Ehlers-Danlos syndrome Classical type, Caffey Disease and idiopathic osteoporosis. Reciprocal translocations between chromosomes 17 and 22, where this gene and the gene for platelet-derived growth factor beta are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans, resulting from unregulated expression of the growth factor. Two transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene. Nucleic acid and amino acid sequences for human COL1A1 (and homologs thereof) are publicly available, such as under NCBI Gene ID 1227. Collagen type I alpha 2 chain (COL1A2): A gene encoding the pro-alpha2 chain of type I collagen whose triple helix comprises two alpha1 chains and one alpha2 chain. Type I is a fibril-forming collagen found in most connective tissues and is abundant in bone, cornea, dermis and tendon. Mutations in this gene are associated with osteogenesis imperfecta types I-IV, Ehlers-Danlos syndrome type VIIB, recessive Ehlers-Danlos syndrome Classical type, idiopathic osteoporosis, and atypical Marfan syndrome. Symptoms associated with mutations in this gene, however, tend to be less severe than mutations in the gene for the alpha1 chain of type I collagen (COL1A1) reflecting the different role of alpha2 chains in matrix integrity. Three transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene. Nucleic acid and amino acid sequences for human COL1A2 (and homologs thereof) are publicly available, such as under NCBI Gene ID 1278. Collagen type III alpha chain (COL3A1): A gene encoding the pro-alpha1 chains of type III collagen, a fibrillar collagen that is found in extensible connective tissues such as skin, lung, uterus, intestine and the vascular system, frequently in association with type I collagen. Mutations in this gene are associated with Ehlers-Danlos syndrome types IV, and with aortic and arterial aneurysms. Two transcripts, resulting from the use of alternate polyadenylation signals, have been identified for this gene. Nucleic acid and amino acid sequences for human COL3A1 (and homologs thereof) are publicly available, such as under NCBI Gene ID 1281. Conservative variants: "Conservative" amino acid substitutions are those substitutions that do not substantially affect or decrease an activity or antigenicity of a protein or peptide. For example, a protein ^{8123-107870-02} disclosed herein can include at most about 1, at most about 2, at most about 3, at most about 4 or at most about 5 conservative substitutions (such as 1, 2, 3, 4, or 5 conservative substitutions, and retain biological activity, such as the ability to promote wound healing. Specific, non-limiting examples of a conservative substitution include the following examples: Original Residue Conservative Substitutions Ala Ser Arg

Lys Asn Gln, His Asp Glu Cys Ser Gln Asn Glu Asp His Asn; Gln Ile Leu, Val Leu Ile; Val Lys Arg; Gln; Glu Met Leu; Ile Phe Met; Leu; Tyr Ser Thr Thr Ser Trp Tyr Tyr Trp; Phe Val Ile; Leu The term conservative variant also includes the use of a substituted amino acid in place of an unsubstituted parent amino acid. Non-conservative substitutions are those that reduce an activity or antigenicity. Controlled delivery composition: A composition in which the rate of release of the component(s) (e.g., drugs, therapeutic agents) is regulated, for example to achieve rapid release and/or delayed release of the component(s). In the context of the present disclosure, rapid release of the first agent that promotes wound closure occurs prior to (or more rapidly than) delayed (or less rapid) release of the second agent that inhibits scarring. Decorin (DCN): A member of the small leucine-rich proteoglycan family of proteins. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature protein. The DCN protein plays a role in collagen fibril assembly. Binding of this protein to multiple cell surface receptors mediates its role in tumor suppression, including a stimulatory effect on autophagy and inflammation and an inhibitory effect on angiogenesis and tumorigenesis.

Nucleic acid and amino acid sequences for human SPARC (and homologs thereof) are publicly available, such as under NCBI Gene ID 6678. Sequence identity: The similarity between nucleic acid or amino acid sequences is expressed in terms of the similarity between the sequences, otherwise referred to as sequence identity. Sequence identity is frequently measured in terms of percentage identity (or similarity or homology); the higher the percentage, the more similar the two sequences are. Homologs or variants of a particular polypeptide will possess a relatively high degree of sequence identity when aligned using standard methods. Methods of alignment of sequences for comparison are well known in the art. Various programs and alignment algorithms are described in: Smith and Waterman, Adv. Appl. Math.2:482, 1981; Needleman and Wunsch, J. Mol. Biol.48:443, 1970; Pearson and Lipman, Proc. Natl. Acad. Sci. U.S.A.85:2444, 1988; Higgins and Sharp, Gene 73:237, 1988; Higgins and Sharp, CABIOS 5:151, 1989; Corpet et al., Nucleic Acids Research 16:10881, 1988; and Pearson and Lipman, Proc. Natl. Acad. Sci. U.S.A.85:2444, 1988. In addition, Altschul et al., Nature Genet.6:119, 1994, presents a detailed consideration of sequence alignment methods and homology calculations. The NCBI Basic Local Alignment Search Tool (BLAST) (Altschul et al., J. Mol. Biol.215:403, 1990) is available from several sources, including the National Center for Biotechnology Information (NCBI, Bethesda, MD) and on the internet, for use in connection with the sequence analysis programs blastp, blastn, blastx, tblastn and tblastx. A description of how to determine sequence identity using this program is available on the NCBI website on the internet. Homologs and variants of a polypeptide are typically characterized by possession of at least about 75%, for example at least about 80%, 90%, 95%, 96%, 97%, 98% or 99% sequence identity counted over the full length alignment with the amino acid sequence of the polypeptide using the NCBI Blast 2.0, gapped blastp set to default parameters. For comparisons of amino acid sequences of greater than about 30 amino acids, the Blast 2 sequences function is employed using the default BLOSUM62 matrix set to default parameters, (gap existence cost of 11, and a per residue gap cost of 1). When aligning short peptides (fewer than around 30 amino acids), the alignment can be performed using the Blast 2 sequences function, employing the PAM30 matrix set to default parameters (open gap 9, extension gap 1 penalties). Proteins with even greater similarity to the reference sequences will show increasing percentage identities when assessed by this method, such as at least 80%, at least 85%, at least 90%, at least 95%, at least 98%, or at least 99% sequence identity. When less than the entire sequence is being compared for sequence identity, homologs and variants will typically possess at least 80% sequence identity over short windows of 10-20 amino acids, and may possess sequence identities of at least 85% or at least 90% or 95% depending on their similarity to the reference sequence. Methods for determining sequence identity over such short windows are available at the NCBI website on the internet. One of skill in the art will appreciate that these sequence identity ranges are provided for guidance only; it is entirely possible that strongly significant homologs could be obtained that fall outside of the ranges provided.

EXAMPLES The following examples are provided to illustrate particular features of certain aspects of the disclosure, but the scope of the claims should not be limited to those features exemplified. Example 1: Background, Materials and Methods This example provides the background, materials and methods for Examples 2-5. Background Mesenchymal stem cells/multipotent stromal cells (MSCs) have emerged as a promising candidate therapy for chronic skin wounds due to their genuine involvement in the early phases of routine wound healing. Upon injury, endogenous bone marrow MSCs home to the site of injury and secrete paracrine signals to modulate the inflammation process and promote angiogenesis (Sylakowski et al., Am J Pathol. Jul 2020;190(7):1370-1381; Bradshaw et al., Curr Pathobiol Rep. Jun 2018;6(2):109-115; Rustad et al., Adv Wound Care (New Rochelle). Aug 2012;1(4):147-152.; Li et al., Front Med. Mar 2011;5(1):33-39). Numerous pre-clinical and clinical studies have looked at the utility of MSCs and the enhanced benefits of their use in treating a myriad of chronic wound conditions (Huang et al., Tissue Eng Part B Rev. Dec ^{8123-107870-02} 2020;26(6):555-570). However, a significant challenge limiting overall MSC therapeutic potential is the poor survival rate and engraftment post-transplantation into the wound bed, with up to 90% of the introduced MSCs being lost within the first three days (Sylakowski et al., Am J Pathol. Jul 2020;190(7):1370-1381; Hu et al., J Thorac Cardiovasc Surg. Apr 2008;135(4):799-808). The chronic wound microenvironment is a hostile culmination of damaged extracellular matrix (ECM), cellular debris, hyper inflammation, and an impaired vasculature (Hu et al., Plast Surg Int.2015;2015:383581; Rodrigues et al., Stem Cell Res Ther. Oct 262010;1(4):32). These factors induce MSC death through various mechanisms, including anoikis, ischemic insult, or increased signaling from death cytokines (Sylakowski et al., Am J Pathol. Jul 2020;190(7):1370-1381; Song et al., Expert Opin Biol Ther. Mar 2010;10(3):309-319). The present disclosure addresses this problem by taking cues from the normal wound healing response and utilizing a naturally occurring matricellular protein called Tenascin-C (TNC). In unwounded skin, TNC is expressed at negligible levels in the papillary dermis just beneath the basement membrane (Lightner et al., J Cell Biol. Jun 1989;108(6):2483-2493). Shortly after injury, TNC is significantly increased at all levels of the skin: in the epidermis through the secretion of epidermal keratinocytes (Latijnhouwers et al., J Invest Dermatol. May 1997;108(5):776-783), at the epidermal-dermal junction just under the basal lamina (Filsell et al., Br J Dermatol. Apr 1999;140(4):592-599), as well as throughout granulation tissue within the dermis (Mackie et al., J Cell Biol. Dec 1988;107(6 Pt 2):2757-2767). TNC is a six-armed glycoprotein composed of four main domains: the TNC assembly domain, the epidermal growth factor-like (EGF-L) repeat domain, the fibronectin type III (FNIII) domain, and a fibrinogen globe domain. The 14.5 EGF-like repeats are found on each arm of the TNC hexamer (Midwood and Orend, J Cell Commun Signal. Dec 2009;3(3-4):287-310). These EGF-like repeats bind to the epidermal growth factor receptor (EGFR) through low affinity/high avidity interactions, allowing for the sequestering of the EGFR to the cell membrane preventing its internalization and degradation (Iyer et al., J Cell Physiol. Jun 2007;211(3):748-758; Swindle et al., J Cell Biol. Jul 232001;154(2):459-468). TNC promotes MSC survival in the face of Fas ligand-induced cell death by binding and sequestering the EGFR, resulting in prolonged activation of the AKT and ERK pro-survival signaling pathways (Rodrigues et al., Stem Cell Res Ther. Oct 262010;1(4):32; Rodrigues et al., Tissue Eng Part A. Sep 2013;19(17-18):1972-1983). MSCs in a TNC-based polymer system in vivo, were able to survive out to 21 days post-transplantation within the wound bed (Yates et al., Cell Transplant. Jan 242017;26(1):103-113). The studies disclosed herein investigate the use of MSCs to promote healing. This study assesses whether the benefit of TNC is not just to promote MSC survival, but also to improve the functional capacity of the wound bed. One of the significant hurdles within the chronic wound bed that newly transplanted cells must encounter is ischemia. Therefore, MSCs cultured on TNC were first subjected to in vitro hypoxia/nutrient deprivation (H/ND) growth conditions and assessed for survival advantages. Next, TNC-supported MSC culture conditions subjected to H/ND were evaluated for angiogenic influence on endothelial cells, as reestablishing new vasculature is necessary to overcome ischemia and progress the wound healing process forward. The last set of experiments were designed to determine how ^{8123-107870-02} TNC-MSC systems would translate in vivo. Since chronic wounds have a characteristically elevated quantity of metalloproteinases (MMPs) and other protein degrading enzymes compared to normal healing wounds (Frykberg and Banks, Adv Wound Care (New Rochelle). Sep 12015;4(9):560-582), a protein delivery system called coacervate was used to help protect TNC against early degradation post-implantation. This system is an injectable in vivo delivery vehicle that uses a positively charged synthetic biodegradable poly(ethylene arginyl aspartate diglyceride) (PEAD) and a negatively charged heparin to form a 3- dimensional coacervate that envelopes around the protein cargo of choice (Johnson and Wang, J Control Release. Mar 102013;166(2):124-129; Johnson and Wang, Wound Repair Regen. Jul-Aug 2015;23(4):591- 600; Park et al., Acta Biomater. May 2019;90:179-191; Li et al., Stem Cells Transl Med. Sep 2013;2(9):667- 677). The animal model used for this study is an impaired wound healing CXCR3^-/- mouse model. This mouse model exhibits a delayed healing response within the dermal and epidermal layers of the skin, leading to an immature dermal matrix, a weakened basement membrane, and hypercellularity (Huen and Wells, Adv Wound Care (New Rochelle). Dec 2012;1(6):244-248; Yates et al., Wound Repair Regen. Jan-Feb 2009;17(1):34-41; Yates et al., Am J Pathol. Aug 2007;171(2):484-495). It was hypothesized that TNC would enhance MSC angiogenic efficacy and thus further contribute to better wound healing outcomes in the delayed wound healing mouse model. Cell Culture MSC Cell Culture – One immortalized bone marrow mesenchymal stem cell (IHMSC) and three primary bone marrow-derived MSC (PrhMSC) lines were used. The IHMSC cell line was a human bone marrow-derived cell line that what immortalized by using human telomerase reverse transcriptase (Shima et al., Biochem Biophys Res Commun. Feb 22007;353(1):60-66). IHMSCs were cultured using the following proliferation media formulation: DMEM with L-Glutamine, 1g/L Glucose and Sodium Pyruvate from Corning (Cat. No.10-014-CV), supplemented with 10% FBS (Cat. No.100-106, Gemini Bio-Products), 1 mM sodium pyruvate, 1 mM L-glutamine, 1 μM non-essential amino acids, and 100 units per mL penicillin-streptomycin. PrhMSCs were obtained from the repository at the Darwin Prockop laboratory at Texas A&M University, a National Institute of Health-funded stem cell repository. PrhMSCs were cultured using the following proliferation media formulation: α-MEM (Cat. No.15-012-CV, Corning) supplemented with 16.5% FBS (Cat. No. S11550H, Atlanta Biologicals), 2 mM L-glutamine, and 100 units per mL penicillin/streptomycin. For hypoxia and nutrient deprivation conditions (H/ND) to mimic ischemia in vitro, MSCs were expanded and seeded near confluence onto one of three treatment coatings (Plastic, Col-1 or TNC+Col-1) and cultured in their fully supplemented DMEM for one day at ambient air conditions (37°C at 5% CO₂ and 21% O2) to stabilize after passaging. Meanwhile, basal DMEM and α-MEM without supplementation or FBS were placed into BioSpherix incubators at 1% oxygen to acclimate the media 24 hours prior to adding to the cells. Upon the start of H/ND experiments of MSCs, the complete culture medias were aspirated, the plates were washed twice with PBS to remove residual media, and pre-equilibrated H/ND media was added ^{8123-107870-02} to the MSCs. The MSCs were then placed into the BioShperix incubators at 1% oxygen. At no point in the culture of cells at 1% were the cells exposed to ambient oxygen conditions, as microscopes to monitor cells were also contained in the BioSpherix chamber. Positive confirmation of hypoxia on MSCs was confirmed through a live cell green hypoxia dye (Cat. No. SCT033, EMD Millipore) as instructed by the company's protocol at the beginning stages of each H/ND experiment (FIG.6). Endothelial Cell Culture – Immortalized Human Microvascular Endothelial Cells (HMEC-1) were obtained through ATCC (Cat. No. CRL-3242; Ades et al., J Invest Dermatol. Dec 1992;99(6):683-690.) and cultured using the following proliferation media formulation: MCDB131 basal media without L-glutamine (Fisher Scientific) supplemented with 10% FBS, 10 ng/mL epidermal growth factor, 1µg/mL hydrocortisone, and 10 mM glutamine. HMEC-1 were thawed and expanded up to passage 3 in proliferation media, then transitioned to either IHMSC or PrhMSC media conditions over a two-week period for functional endpoint experiments. By Passage 6 HMEC-1s were fully transitioned to MSC media conditions and used for cell migration and cord formation studies. Coating Culture Plates with Col-1 and TNC Cell culture plate coating procedures and concentrations used for Tenascin-C (TNC) (Cat. No. CC065, EMD Millipore) and type 1 rat tail collagen (Col-1)(Cat. No.354236, BD Biosciences) were as previously described (Rodrigues et al., Tissue Eng Part A. Sep 2013;19(17-18):1972-1983). In short, cell culture dishes were coated for 12 hours at 37°C with 1 μg/cm² Col-1, or 1 μg/cm² Col-1 and 1 μg/cm² TNC diluted in PBS. After the incubation period, the PBS was aspirated, and the coated surfaces were placed under UV light for 30 minutes before seeding any cells. The Col-1 was required for the TNC-coated plates, as TNC is anti-adhesive and requires additional integrin-binding epitopes as provided by the collagens (Rodrigues et al., Tissue Eng Part A. Sep 2013;19(17-18):1972-1983). Apoptosis Assessment Two methods determined cell death. In the first method, flow cytometry combined with an Annexin V and propidium iodide (PI) kit (Cat. No. V13242, Thermo Fisher Scientific) were performed as per manufacturers' instruction. In brief, MSCs cultured under H/ND growth conditions on either plastic, Col-1, or TNC+Col-1 were harvested by collecting adherent cells and floating cells in the supernatant. The floating and adherent cells were combined and stained for PI and Annexin V for 15 minutes at room temperature. An appropriate volume of 1X annexin-binding buffer and counting beads (Cat. No. C36950, Thermo Fisher Scientific) were added and the tubes placed on ice. Samples were run through a BD FACSCanto II flow cytometer and analyzed using FlowJo_V10. An unstained control for each cell type was used to determine positive and negative stained cells and counting beads were used to determine the absolute number of cells per treatment condition for quantification. For the second method, MSCs were seeded onto 6-well plates for each condition (plastic, Col-1, or TNC+Col-1) and subjected to H/ND. Old media was removed, PBS with CellEvent caspase 3/7 green ^{8123-107870-02} detection reagent (Cat. No. C10423, Thermo Fisher Scientific), and 5% FBS was added to each well and left to incubate for 30 minutes at 37°C. Cells were imaged and quantitated using ImageJ, where all images were converted to 8-bit format, and the threshold was reduced to highlight the green punctae in culture, using the same thresholding for all analyzed images. Particle analysis in ImageJ was set to detect fluorescent points with a radius greater than 50 pixels to exclude debris and background fluorescence. The number of caspase 3/7 positive and negative cells were calculated and expressed as a percentage of Caspase 3/7 positive staining. This second method procedure was also used to determine the survival time course during exposure to H/ND, but instead of using caspase 3/7, PI from the provided Annexin V/PI kit was initially used. Preparation of Conditioned Media Conditioned media (CM) was harvested at 96-hour time point from the four MSC lines cultured under H/ND growth conditions on either plastic, Col-1, or TNC+Col-1. CM was then centrifuged for 10 min at 10,000 rpm to remove cells and cellular debris. The supernatant was collected and frozen for downstream assays. Cord Formation Assay Cord formation assays were performed using µ-slide angiogenesis glass-bottom slides (Cat. No. 81507, Ibidi) as per manufacturers' instruction. In brief, growth factor reduced Matrigel (Cat. No.356231, BD Biosciences) was seeded in the bottom well of the ibidi angiogenesis plates and allowed to polymerize for 30 minutes at 37°C. While the gel was polymerizing, low passage fully transitioned HMEC-1 cells were trypsinized, counted, and mixed with a ratio of 50% basal media and 50% freshly thawed CM for each treatment condition. Basal media alone was used as the negative control, while basal media with 10% FBS was used as the positive control. Cells were then seeded into the Ibidi angiogenesis chamber at 2x10⁵ and placed into a 37°C incubator with ambient growth conditions. Cords were allowed to form over the next 6 hours before being quantified using ImageJ Angiogenesis Analyzer (Carpentier et al., Sci Rep. Jul 14 2020;10(1):11568) and expressed as a total number of cords, total cord length, the total number of meshes, and total mesh area. Cords are the sum of segments (elements bordered by two junctions) and branches (elements bordered by a junction and one extremity); and a mesh is defined as an area enclosed by segments (Carpentier et al., Sci Rep. Jul 142020;10(1):11568). Scratch Assay Cell migration was assessed using the wound healing (or scratch) assay. HMEC-1 were seeded into 24 well plates and allowed to grow to confluence. Upon reaching confluence, the cells were washed in PBS and then cultured in basal media containing 1% dialyzed FBS for 24 hours to limit proliferation during the study. The next day using a 1000 mL pipette tip, scratches were made down the middle of each plate to create a denuded area. Each well was washed twice with PBS to remove cellular debris after the scratch was made. A mixture of 50% basal media with 1% FBS and 50% CM from each treatment condition were added ^{8123-107870-02} to their respective wells. Basal media alone was used as the negative control while basal media with 10% FBS was used as the positive control. Images were acquired at 0 and 24 hours, and the area unoccupied by the migrating cells was determined using Image J and expressed as % wound closure. Cytokine Measurement MSCs were seeded onto 6-well plates for each condition (plastic, Col-1, or TNC+Col-1) and subjected to H/ND. At 96 hours, CM was collected, centrifuged to remove cellular debris, and frozen until ready to use. To determine angiogenic factors in the MSC CM, a semi-quantitative human angiogenesis antibody array (Cat. No. AAH-ANG-1000-2, RayBiotech) was used according to the instructions as outlined in their protocol. In brief, 1 mL of CM from each MSC treatment group was placed on a specialized PVDF membrane with specific angiogenic capture antibodies and incubated overnight at 4°C. A series of washes and conjugation of biotinylated antibodies were performed following the incubation period. According to the kit's protocol, membranes were washed 3 times more and detected using labeled streptavidin and chemiluminescence. Radiographs were processed and analyzed using ImageJ Dot Blot analyzer plug-in. RT-PCR Analysis MSCs were seeded onto 6-well plates for each condition (plastic, Col-1, or TNC+Col-1) and subjected to H/ND. At 48 hours, MSC treatment conditions were washed with PBS, trypsinized and pelleted, and RNA was isolated using RNeasy kit (Cat. No.74004, Qiagen). Quality and concentration analysis of RNA samples was assessed using a nanodrop instrument and stored at -80°C. Next, the Isolated RNA samples were synthesized into cDNA using The RT² First Strand c-DNA Synthesis Kit from Qiagen (Cat. No.330404, Qiagen). MSC angiogenic and wound healing genes were assessed using Qiagen RT² Profiler Array System (Cat. No. PAHS-024ZA-12 and PAHS-121ZA-12, Qiagen). RT-PCR was performed on the Stratagene Mx3000P Real-Time PCR System with the Qiagen RT2 SYBR Green qPCR Master Mix (Cat. No.330523, Qiagen). Samples were analyzed using the ΔΔCT method plus or minus standard error and expressed in terms of fold regulation. MSCs grown on Col-1 and TNC+Col-1 were normalized back to MSCs grown on plastic, and GAPDH was used as the reference gene. Fold-regulation is similar to fold change in that positive values greater than one indicate up-regulation; however, fold-change values less than one that indicates down-regulation have now been transcribed to the negative inverse. For this analysis, 2 and -2 were used as fold regulation cut-off numbers for anything of importance; and CT values more than 32 were seen as likely biologically irrelevant. Animal Model C57BL/6J CXCR3-/- mice were generated as previously described (Hancock et al., J Exp Med. Nov 202000;192(10):1515-1520). The C57BL/6J CXCR3^-/- mice were then bred to FVB strain mice for at least 20 generations to yield germline transmission of the targeted allele and create CXCR3 devoid mice on the FVB background. For this study, CXCR3^-/- female mice were bred with CXCR3^-/- males, and all offspring ^{8123-107870-02} were screened for genotype through PCR before use. Serological analyses did not detect blood-borne pathogens or evidence of infection. Mice were housed in individual cages after wounding to limit fighting and further scarring and maintained under a 12-hour light/dark cycle. Mouse Wounding Male and female mice (8 to 9 months of age and weighing approximately 25 g) were anesthetized with an intraperitoneal injection containing ketamine (75 mg/kg) and xylazine (5 mg/kg). The backs were cleaned, shaved, and sterilized with betadine solution. Full-thickness wounds were performed using an 8 mm diameter punch biopsy through the epidermal and dermal layers along one side of the dorsal midline of the mouse (FIG.7A). The contralateral uninjured skin served as unwounded control skin. Coacervate Preparation and Mouse Injections PEAD was synthesized as previously described (Chu et al., J Control Release. Mar 10 2011;150(2):157-163). Stock solutions of PEAD and heparin (10 mg/mL) were prepared in 0.9% saline solution using a 0.22 µm sterile syringe filter. Human Tenascin-C purified protein (Cat. No. CC065, EMD Millipore) was reconstituted to 300 µg/mL and mixed with heparin stock solution at their respective predetermined working dose of 10 µg per animal. The heparin/TNC solution was then mixed with the PEAD stock solution to form protein-encapsulated coacervates at a final ratio of 1:100:500 mass ratio. Coacervation was determined by the rapid formation of a turbid solution once all components were added. The prepared coacervate mixture was then mixed with a prepared cell suspension of 50x10⁴ IHMSCs per mouse for a total injection volume of 300 µL per mouse. Intradermal Injections were administered 72 hours post wounding. Each mouse received 300 µL of one of five treatment options: CO only, CO+TNC, CO+MSC, TNC+MSC, or CO+TNC+MSC, through a series of 4 injections of 75 µL around the wound bed to avoid tissue trauma (FIG.7A). Each treatment group comprised of 4 animals each. Coacervate Release Coacervate was prepared as stated above to create three independent samples for coacervate containing TNC. Samples were incubated at 37ºC for 14 days, and the supernatant was harvested on days 0, 1, 3, 7, and 14 through pelleting the coacervates by centrifugation (12,100g for 10 min). Supernatants were analyzed using pre-coated enzyme-linked immunosorbent assay (ELISA) kits (Cat. No. ab213831, Abcam), according to the manufacturer's specifications (FIG.7B). Histological Analyses Wound bed biopsies were collected after euthanasia at day 30 using a 12 mm punch biopsy and were immediately fixed in 10% buffered formalin. Samples were then paraffin embedded (FFPE), sectioned into slides (6 μm), and stained with H&E and Masson's Trichrome (MT). Blank slides were also made for ^{8123-107870-02} downstream Picrosirius Red (PSR) staining as directed by the manufacturer's protocol (Cat. No.150681, Abcam) and for follow up immunohistochemistry and immunofluorescent stains. Wound healing score assessment – Histopathological examination of mouse tissues was performed in a double-blind approach among three investigators, and their scores averaged. Qualitative assessments were based on epidermal and dermal maturation as outlined in previously established protocols (Yates et al., Wound Repair Regen. Jan-Feb 2009;17(1):34-41; Yates et al., Am J Pathol. Aug 2007;171(2):484-495; Yates et al., Am J Pathol. Sep 2008;173(3):643-652). In short, the samples were scored on a scale of 0 to 4 for both epidermal and dermal layers of tissue. For epidermal maturation scoring: 0 = no epidermal migration, 1 = partial epidermal migration, 2 = complete epidermal migration, 3 = partial keratinization and an intact basement membrane, 4 = complete keratinization and normal epidermis. For dermal maturation scoring: 0 = no healing, 1 = inflammatory infiltration, 2 = granulation tissue present – fibroplasias and angiogenesis, 3 = collagen deposition replacing granulation tissue > 50%, 4 = complete replacement of granulation tissue and complete healing. Skin thickness measurements – H&E and MT sample images were analyzed using ImageJ line measurement tool to measure the thickness of the epidermal and dermal layers for each mouse specimen. The epidermal layers were measured from the stratum basale to the stratum granulosum (excluding the stratum corneum), and the dermal layer was measured from the top of the papillary layers to the bottom of the reticular layer. A total of 6 measurements per biological sample were scored for each layer. Collagen quantification – Polarized PSR images were quantified using ImageJ version 1.53K. Each image was split into red, green, and blue channels, from which the red and green channels were selected. The isolated red and green channels then underwent thresholding and follow-up measurements to determine the total staining area for each collagen type. PSR birefringence under polarized light reveals tightly packed thick and long fibrils of type 1 collagen as either bright red-orange intense birefringence in tissue and thin short loose fibrils as yellow-green (Coelho et al., An Bras Dermatol. Jun 2018;93(3):415-418). The overall ratio of type 1 collagen to type III collagen was analyzed by comparing the representative staining results for either collagen type back to the original image for total collagen content. Collagen orientation and alignment – Polarized PSR images were quantified using ImageJ plug-in: OrientationJ version 2.0.5. Visual directional analysis using the color survey tool was performed with the following parameters: Hue is set for orientation, Saturation is set for coherency, and brightness is set to the original image (Puspoki et al., Adv Anat Embryol Cell Biol.2016;219:69-93). The OrientationJ distribution tool was used to create the distribution of orientation histograms to determine where patterns of alignment were within the samples (Rezakhaniha et al., Biomech Model Mechanobiol. Mar 2012;11(3-4):461-473). The OrientationJ Dominant Direction tool was used to determine the quantitative orientation measurement for coherency across the whole image (Fonck et al., Stroke. Jul 2009;40(7):2552-2556). Immunohistochemistry staining– Skin sample tissue sections (6 µm) were rehydrated and placed into citrate acid buffer at 95°C for 10 minutes and cooled to room temperature for 1 hour. Samples were then washed in phosphate-buffered saline (PBS) and quenched with 3% hydrogen peroxide. Following additional ^{8123-107870-02} washes in PBS, samples were blocked in 20% goat serum for 1 hour and subsequently incubated with primary antibodies diluted in blocking buffer overnight at 4ºC. Primary antibodies were at the following dilutions: CD31 (1:50, Cat. No. ab28364, Abcam). After primary antibody incubation, samples were washed in PBS and incubated in goat anti-rabbit HRP secondary antibody (1:2000, Cat. No. ab205718, Abcam) for 1 hour at room temperature. After final antibody incubations, samples were washed in PBS and then treated with ABC reagent (Cat. No. PK-6100, Vector Laboratories) for 30 minutes. Rewashed with PBS and developed with DAB reagent kit 27 (Cat. No. SK-4100, Vector laboratories), counterstained with H&E, clarified (Richard Alan Scientific), and dehydrated in ethanol and xylene. Samples were mounted (Cat. No. SP15-500, Fisher Scientific) and imaged using an Olympus Provis microscope. Image analysis was performed using Image J Colour Deconvolution 2 plug-in to acquire DAB positive staining area. The total DAB positive area was compared back to the total area of the original image to get a final percentage. Statistical Analysis Data for the in vitro cell survival and cytokine array are presented as the mean ± standard deviation, whereas the cord formation and cell migration assays are presented as the mean ± s.e.m. All in vitro studies were performed using four biological replicates with at least 2 technical replicates. Results from animal wound healing score assessment and PSR staining assessment are expressed as mean ± SD with at least a minimum of four mice per treatment group. Histological quantifications for skin layer thickness and immunohistological stains (CD31) were performed on five microscopic fields of each specimen and reported as mean ± s.e.m. One-way ANOVA determined statistical analysis between treatment groups for all experiments except for the survival time course for which two-way ANOVA was used to distinguish significance. Both ANOVA analyses were followed by posthoc Tukey HSD analysis using GraphPad Prism 9 software (GraphPad Software, San Diego, CA). Significance was claimed for P<0.05. Significance is represented in all figures with symbols denoting *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001 Example 2: Tenascin-C protects MSCs under ischemic conditions in vitro One of the major obstacles facing MSC survival and engraftment within chronic wounds is ischemia. TNC has been shown to protect MSCs against inflammatory death signals (Rodrigues et al., Tissue Eng Part A. Sep 2013;19(17-18):1972-1983), and the current study aims to determine whether this matricellular protein also ameliorates the ischemia due to lack of angiogenesis. An ischemic environment was created in vitro using a Biospherix growth chamber (Nuschke et al., Stem Cell Res Ther. Dec 1 2016;7(1):179). A cell survival time course was made using Propidium Iodide (PI) as a marker for dead cells. A significant difference was observed at day 7 between treatment groups (MSC on plastic, MSC on Col-1, or MSC on TNC+Col-1) under H/ND conditions (FIG.8A). MSCs cultured on TNC+Col-1 had much lower PI incorporation when compared to MSCs cultured on either plastic (34%) or Col-1 alone (48%). Additionally, MSCs cultured on Col-1 showed better survival over MSCs cultured on plastic, though not to the degree of TNC+Col-1. The survival changes around Day 7 were further analyzed using flow cytometry ^{8123-107870-02} with a combination of PI and Annexin V cell death markers. In this system, PI can detect necrotic or late apoptotic cells through the loss in integrity of the plasma membrane, and Annexin V signals early apoptosis through detection of plasma membrane flipped phosphatidylserine as well as late apoptosis. A snapshot of this transition at day 7 revealed that only 2.09% of the MSCs on plastic did not transition through apoptosis (PI-/Annexin V-); compared to the survival rates of MSCs on Col-1 at 29.9% or MSCs on TNC+Col-1 at 40.2%; the survival on TNC+Col-1 was significantly higher than Col-1 alone (FIGS.1A, 1B and 8B). To confirm the flow cytometry data results, an additional set of staining experiments were performed with a live cell green caspase 3/7 stain and apoptosis was quantified on day 7 (FIGS.1C, 1D). Once again, MSCs cultured on plastic were significantly limited in survivability, with mean positive staining for caspase 3/7 of 39%, while MSCs cultured on Col-1 or TNC+Col-1 had lower mean caspase 3/7 staining rates of 31% and 27%, respectively. With caspase 3/7, the difference between the Col-1 and TNC+Col-1 survival rates did not reach statistical significance; this could be due to the loss of dead cells floating off the bottom of the plate, where these were captured and quantified in the flow analysis. The data indicate that MSCs seeded on TNC+Col-1 have significantly higher protection against the ischemic microenvironment than MSCs cultured on plastic alone and a slightly higher survival rate than MSCs cultured on Col-1. Example 3: Conditioned media from MSCs cultured on Tenascin-C improves endothelial cord formation and motility TNC can contribute to the wound angiogenic response by enhancing MSC-produced angiogenic factors. To assess TNC's influence on MSC's ability to modulate the ischemic wound environment and improve vascularization, studies were performed to evaluate the angiogenic effects of MSC conditioned media (CM) on endothelial cells in vitro. CM was harvested from MSCs cultured on either plastic, Col-1, or TNC+Col-1 under H/ND conditions and used with HMEC-1 plated on a reduced growth factor Matrigel surface to commence cord formation (FIG.2A). Overall, CM from all three treatment groups performed equal to or better than the positive control of basal media + 10% FBS across all metrics (FIG.2B). However, the CM from MSC cultured on TNC+Col-1 scored significantly higher than MSCs cultured on plastic for total cord length, the total number of meshes, and total mesh area. Additionally, CM from MSCs cultured on TNC+Col-1 had significantly longer length and a higher number of cords compared to CM from MCSs cultured on Col-1 alone, and trended higher on the other matrices though the increases did not reach statistical significance. After assessing the potential angiogenic influences, further studies sought to examine the cell motility effects of the different culture conditions through a wound-healing/scratch assay. CM harvested from the varying MSC culture conditions (plastic, Col-1, TNC+Col-1) were placed into confluent HMEC-1 wells with a denuded strip in the center to allow for cell migration. Images were taken at 0 and 24 hours post addition of the CM, and cell migration into the denuded area was measured (FIGS.2C, 2D). Unlike in the cord formation assay, none of the MSC treatment groups outperformed the positive control group this time. The basal media negative control had a wound closure rate of 23%, while CM from both plastic and Col-1 ^{8123-107870-02} scarcely outperformed at 28% and 30%. CM harvested from TNC+Col-1 performed significantly better with a wound closure rate of 43%. Overall, TNC's interactions with MSCs have a pro-angiogenic effect. Example 4: Assessment of culture conditions on MSC paracrine activity and gene expression during H/ND exposure The physiological outcomes of CM on endothelial function prompted exploration of what factors could be at play. Utilizing an aliquot of CM from the different MSC culture conditions, angiogenic cytokines were measured utilizing an angiogenesis array for 43 protein targets (FIGS.3A, 3B). Of the 43 targets, 6 proteins were substantially expressed including IL-6, IL-8 (CXCL8), TIMP-1, TIMP-2, CCL2 (MCP-1), and Gro alpha/beta/gamma (CXCL1, CXCL2, CXCL3). All protein hits were expressed by all three CM treatment groups, with only TIMP-1 exhibiting a significant difference between CM from plastic and CM from TNC+Col-1, though the fold increase was minimal. Follow-up gene expression analysis for these 6 protein targets revealed no significant differences at the mRNA level between treatment groups (FIG.3C). To explore other possible differences between the treatment groups, each sample was run on two qPCR profilers to explore gene targets relating to angiogenesis and wound healing (FIGS.9A, 9B). Out of 138 unique genes in total from both arrays, there were 14 genes that either had an upregulation or downregulation of 2 or more, summarized in the table of FIG.9C. However, only Col5A2 upregulated in CM from MSC on TNC+Col-1 was statistically significant with a p-value of 0.027. Example 5: Coacervate with TNC and MSC improves wound healing in vivo in delayed wound healing mouse model Further studies were performed to determine whether the findings in vitro would improve the healing outcomes in a CXCR3 -/- mouse model of delayed wound healing (Yates et al., Wound Repair Regen. Jan-Feb 2009;17(1):34-41; Yates et al., Am J Pathol. Aug 2007;171(2):484-495). Wounds were made in the CXCR3 -/- mice, and one of five treatment groups (CO only, CO+TNC, CO+MSC, TNC+MSC, or CO+TNC+MSC) were administered 72 hours after the initial wounding. The wounds were harvested on D30 during the middle of the delayed tissue replacement phase of wound healing (Sylakowski et al., Am J Pathol. Jul 2020;190(7):1370-1381). At this point in the wound healing process, histological stains using H&E and Mason’s Trichrome (MT) reveal complete migration and stratification of the epidermis, along with a fully intact basement membrane indicating complete wound healing of the epidermal layer with a wound score of a 4 (FIGS.4A, 4B, 4E). However, when looking at epidermal thickness as a restorative measure, treatment with CO+TNC+MSC was significantly thinner than CO Only, CO + TNC, and CO + MSCs. The treatment group with CO + MSCs trended much higher than all the rest in terms of epidermal thickness. Transitioning to the dermal layer, there was higher cellularity in the mice treated with CO only and CO + MSCs compared to the other treatments (FIGS.4A, 4B); this indicated the wound healing sequence was delayed with these treatments, and indicated a correction of the defect with the other treatments. Next, staining for platelet endothelial cell adhesion molecule (PECAM-1 or CD31) was performed to assess ^{8123-107870-02} differences in angiogenesis and capillary formation (FIGS.4C, 4D). A statistically significant higher number of capillaries were observed in mice treated with CO + TNC + MSCs and CO + TNC compared to CO only control. When examining the MT staining, the CO + TNC treatment group appeared to have the highest amount of granulation collagen due to the lightness of the blue color (FIG.4B). The mice treated with CO + TNC + MSCs exhibited the darkest color of collagen, signifying higher collagen turnover from immature Col-III to mature Col-I. Further quantification of collagen Col-1/Col-III ratio using Picrosirius Red (PSR) stain confirmed this observation, where mice treated with CO + TNC + MSC had a significantly higher Col-1/Col-III ratio compared to CO only, CO + TNC, and CO + MSC (FIGS.5A, 5B, 5D). The CO only, CO + TNC, and CO + MSC treatment groups had a Col-1/Col-III ratio close to 1, indicating they were still early in the tissue replacement phase with a lot of granulation tissue. The CO + TNC + MSC mice had a Col-1/Col-III ratio above 1.5 and approaching 2, indicating active collagen maturation and entry into the resolution phase of wound healing. Normal unwounded skin has a Col-1/Col-III ratio of 2 or higher. In addition to collagen content quantification, collagen alignment scoring can also help determine the maturity of collagen within the dermis. Upon healing a wound within the murine model who doesn't have rete ridges, the dermal layer alignment becomes more horizontal as the collagen becomes more mature and contracted via the myofibroblasts. The overall alignment of the collagen fibrils was observed using the ImageJ color survey tool (FIG.5C). This allows the PSR stain to be pseudo-colored according to their alignment orientation. From this view, the orientation can be analyzed in two ways. The first collagen alignment method was to look at the total distribution of all collagen fibrils relative to their degree of alignment (FIG.5E). A skewed bimodal distribution was seen in all treatment groups with one peak around the -50 degree orientation mark and the other around the +50 degree orientation mark. The mice treated with the CO + TNC + MSC group had the tallest peak out of all the treatment groups at the +50 mark, indicating it has the most alignment in that location. It is also the highest peak out of all peaks on the graph, signaling it is the most aligned of all treatment groups. The two treatment groups with the lowest collagen alignment score were CO + TNC and CO + MSCs. The second way to measure collagen alignment is through total measured coherency. This measures the overall coherency of the collagen fibrils within each image with a total coherency measure between 0 and 1, where 0 indicates complete isotropy and 1 indicates complete alignment (Rezakhaniha et al., Biomech Model Mechanobiol. Mar 2012;11(3-4):461-473). Similar to what was observed in the first collagen alignment method, the mice treated with CO + TNC + MSCs had a significantly higher coherency score compared to CO only, CO + TNC, or CO + MSCs (FIG.5F). The mice treated with TNC + MSC without coacervate also exhibited good alignment with coherency scores significantly higher than CO only and CO + TNC treatment groups. For one last measure of collagen maturation in terms of contraction, mice treated with CO + TNC + MSCs and TNC + MSCs presented significantly thinner dermal thickness scores than the other three treatment methods (FIG.4F). Overall, mice treated with CO + TNC + MSCs had the highest wound score, closely followed by TNC + MSCs without coacervate (FIG.4E), whereas mice treated with CO only and Co + MSCs exhibited the least amount of ^{8123-107870-02} maturation in most metrics. These findings demonstrate that TNC inclusion improves the performance of MSCs in promoting maturation of wounds through the phases of healing. Example 6: Background, Materials and Methods Cutaneous wound healing is a highly complex and dynamic process that requires a successful transition through three phases of repair to reach a successful resolution. This process relies critically on the timing and balance of key cell types, growth factors, and extracellular matrix (ECM) molecules to maintain proper outcomes. However, patients who have experienced extreme trauma or severe burns can disrupt this complex network of pro-fibrotic and anti-fibrotic interactions and signals, leading to an excessive deposition of collagen and the formation of hypertrophic scars (HTS) (Zhu et al., Burns Trauma.2016;4:2). Patients with severe HTS are subject to high psychological and physical impairment levels, as these wounds are often found in areas of high skin tension and can be very resistant to treatment or therapy (Bock et al., Arch Dermatol Res. Apr 2006;297(10):433-438). One of the critical elements of HTS is the imbalance of the ECM throughout the wound healing process. Early in the HTS wound healing process, the wound micro-environment is often plagued with chronic inflammation leading to an overabundance of matrix metalloproteinases (MMPs) and disproportionate breakdown of ECM (Zhu et al., Burns Trauma.2016;4:2; Yates et al., Birth Defects Res C Embryo Today. Dec 2012;96(4):325-333; Ghazawi et al., Adv Skin Wound Care. Jan 2018;31(1):582-595; Gauglitz et al., Mol Med. Jan-Feb 2011;17(1-2):113-125). This in turn, creates a response for fibroblasts in the next phase of repair to excessively proliferate and produce an overabundant amount of collagen, ultimately leading to HTS (Zhu et al., Burns Trauma.2016;4:2; Yates et al., Birth Defects Res C Embryo Today. Dec 2012;96(4):325-333; Ghazawi et al., Adv Skin Wound Care. Jan 2018;31(1):582-595; Gauglitz et al., Mol Med. Jan-Feb 2011;17(1-2):113-125; Oliveira et al., Int Wound J. Dec 2009;6(6):445-452). In addition to the changes observed to ECM structural proteins such as collagen in HTS patients, other non- structural ECM proteins called matricellular proteins are also affected. These specialized ECM proteins do not provide structure or scaffolding support for cells; instead, they directly interact with cell signaling through the interaction of growth factors, growth factor receptors, and other ECM proteins within the wound microenvironment, driving a variety of biological signaling cascades. One of these vital matricellular proteins is called decorin, and it acts as a stop signal within the resolution phase of wound healing. Decorin (DCN) is a small leucine-rich proteoglycan roughly 100 kDa in size. It consists of a core protein element composed of 10-12 tandem leucine-rich repeats (LRR) attached to a single N-terminal glycosaminoglycan chain (GAG) (Chen and Birk, Front Pharmacol.2019;10:1649; Pang et al., Front Pharmacol.2019;10:1649). Its name is derived by its ability to bind or "decorate" collagen fibrils and is found throughout the reticular dermis of the skin (Pang et al., Front Pharmacol.2019;10:1649). DCN’s ability to interact with collagen allows for it to be a key component of collagen fibrillogenesis during wound healing as it helps to regulate collagen fibril diameter, organization, and spacing between collagen strands (Kadler et al., Curr Opin Cell Biol. Oct 2008;20(5):495-501; Danielson et al., J Cell Biol. Feb 10 ^{8123-107870-02} 1997;136(3):729-743). Additionally, it can regulate other signaling cascades within the wound microenvironment, often acting as a non-competitive antagonist for a host of growth factors and growth factor receptors (Buraschi et al., Matrix Biol. Jan 2019;75-76:260-270; Merline et al., J Cell Commun Signal. Dec 2009;3(3-4):323-335; Neill et al., Am J Pathol. Aug 2012;181(2):380-387; Gubbiotti et al., Matrix Biol. Sep 2016;55:7-21). One critical signaling receptor DCN will bind to during the resolution phase is the vascular endothelial growth factor (VEGF) receptor 2 of endothelial cells, inducing an autophagic response and suppressing angiogenesis during this repair phase (Sylakowski and Wells, Matrix Biol. Jun 2021;100-101:197-206; Buraschi et al., Proc Natl Acad Sci U S A. Jul 92013;110(28):E2582-2591). DCN also regulates transforming growth factor – beta-1 (TGF-β1), a significant influencer of wound contraction, by either binding and neutralizing the growth factor directly or by downregulating its production from hypertrophic scar fibroblasts (Gubbiotti et al., Matrix Biol. Sep 2016;55:7-21; Zhang et al., Burns. Aug 2007;33(5):634-641; Zhang et al., Burns. Jun 2009;35(4):527-537). CXCR3 is a seven transmembrane G-protein coupled receptor that is the sole receptor for CXCL4, CXCL9, CXCL10 and CXCL11, the latter two of which are expressed during wound healing at the time of the transition from tissue replacement to wound resolution. Mice lacking the CXCR3 receptor display a delayed but prolonged dermal wound healing phenotype that leads to hypertrophic scarring (Yates et al., Am J Pathol. Aug 2007;171(2):484-495; Yates et al., Am J Pathol. Apr 2010;176(4):1743-1755). Correction of the scarring defect using cellular transplants reverses the matrix progression back towards near regenerative healing (Yates et al., Stem Cell Res Ther. Sep 52017;8(1):193; Yates et al., Cell Transplant. Jan 24 2017;26(1):103-113; Sylakowski et al., Am J Pathol. Jul 2020;190(7):1370-1381). Thus, studies described below were performed to determine if directly pharmacologically altering the matrix can achieve better healing as it would be easier than cellular transplants. DCN plays an important role in proper wound resolution, and its protein levels are found to be decreased roughly 75% in HTS compared to regular wound healing patients (Gauglitz et al., Mol Med. Jan-Feb 2011;17(1-2):113-125; Finnerty et al., Lancet. Oct 1 2016;388(10052):1427-1436). However, delivery of exogenous growth factors or other protein-based therapies is often limited in their efficacy due to extensive degradation once administered in vivo into the harsh wound microenvironment (Hwang et al., Front Bioeng Biotechnol.2020;8:69). To overcome this challenge, DCN was encapsulated in a heparin-mediated coacervate system. This system is an injectable in vivo delivery vehicle that uses a positively charged synthetic biodegradable poly(ethylene arginyl aspartate diglyceride) (PEAD) and a negatively charged heparin to form a 3-dimensional coacervate (Johnson and Wang, Wound Repair Regen. Jul-Aug 2015;23(4):591-600; Park et al., Acta Biomater. May 2019;90:179- 191; Chu et al., J Control Release. Mar 102011;150(2):157-163; Johnson and Wang, J Control Release. Mar 102013;166(2):124-129). This delivery approach allows for the protection of the DCN while also allowing for its controlled release over several days (FIG.10A). As a control modulator, heparin-binding EGF-like growth factor (HB-EGF) was used as it has been shown to accelerate delayed healing in a mouse model of diabetic wounds (Johnson and Wang, Wound Repair Regen. Jul-Aug 2015;23(4):591-600). It was ^{8123-107870-02} hypothesized that delivery of DCN would result in a reduced scarring phenotype and an overall better healing outcome in the hypertrophic scarring mouse model. Animal Model C57BL/6J CXCR3 -/- mice were generated as previously described (Hancock et al., J Exp Med. Nov 202000;192(10):1515-1520). The C57BL/6J CXCR3 -/- mice were then bred to FVB strain mice for at least 20 generations to yield germline transmission of the targeted allele and create CXCR3 devoid mice on the FVB background. For this study, CXCR3 -/- female mice were bred with CXCR3 -/- males and all offspring were screened for genotype through PCR before use. Serological analyses did not detect blood- borne pathogens or evidence of infection. Mice were housed in individual cages after wounding and maintained under a 12-hour light/dark cycle. Wounding Male and female mice (6 to 8 months of age and weighing approximately 25 g) were anesthetized with an intraperitoneal injection containing ketamine (75 mg/kg) and xylazine (5 mg/kg). The backs were cleaned, shaved, and sterilized with betadine solution. Full-thickness wounds were performed using an 8 mm diameter punch biopsy through the epidermal and dermal layers along one side of the dorsal midline of the mouse. The contralateral uninjured skin served as unwounded control skin. Coacervate Preparation PEAD was synthesized as previously described (Chu et al., J Control Release. Mar 10 2011;150(2):157-163). Stock solutions of PEAD and heparin (10 mg/mL) were prepared in 0.9% saline solution and passed through a 0.22 µm sterile syringe filter. Recombinant human HB-EGF (Cat. No.50-398- 861, PeproTech) and DCN (Cat. No.143DE100 R&D Systems) were each reconstituted to 300 µg/mL and mixed with heparin stock solution at their respective predetermined working doses of 1.45 µg for HB-EGF (Johnson and Wang, Wound Repair Regen. Jul-Aug 2015;23(4):591-600) and 10 µg for DCN (Krishna et al., Otolaryngol Head Neck Surg. Dec 2006;135(6):937-945). The heparin/HB-EGF and heparin/decorin solutions were then each mixed with PEAD stock solutions to form protein-encapsulated coacervates at a final ratio of 1:100:500 (protein:heparin:PEAD) mass ratio. Coacervation proceeded rapidly with the formation of a turbid solution once all components were mixed. Coacervate Mouse Injections Intradermal injections were administered once on day 7 for mice being harvested on day 14. Whereas mice that were harvested at day 30 or 90 received two rounds of injections, at day 7 and day 14. For each treatment, a mouse received a total of 200 µL of either treatment coacervate or control coacervate through a series of 4 injections of 50 µL around the wound bed to avoid tissue trauma (FIG.10A). Mice ^{8123-107870-02} treated with HB-EGF coacervate received a dose of 200 µL containing a total of 1.45 µg HB-EGF, while mice treated with DCN received a dose of 200 µL containing a total of 10 µg DCN. Coacervate Release Coacervate was prepared as stated above to create three independent samples for both HB-EGF and DCN. Samples were incubated at 37ºC for 14 days, and the supernatant was harvested on days 0, 1, 3, 7, and 14 through pelleting the coacervates by centrifugation (12,100g for 10 min). Supernatants were analyzed using pre-coated enzyme-linked immunosorbent assay (ELISA) kits (Cat. No. EHHBEGF and Cat. No. EHDCN, Thermo Fisher Scientific), according to the manufacturer's specifications. The release profiles were as previously published for HB-EGF (FIG.10C) (Johnson and Wang, J Control Release. Mar 10 2013;166(2):124-129), and slightly faster for DCN as befits its larger size and lack of proteoglycan binding domain (FIG.10B). Histological Analyses Wound bed biopsies were collected after euthanasia at days 14, 30, and 90 using a 12 mm punch biopsy and were immediately fixed in 10% buffered formalin. Samples were then paraffin embedded (FFPE), sectioned into slides (6 μm), and stained with hematoxylin and eosin (H&E) and Masson's Trichrome (MT). Blank slides were also made for downstream Picrosirius Red (PSR) staining as directed by the manufacturer's protocol (Cat. No.150681, Abcam) and followed by immunohistochemistry and immunofluorescent stains. Wound healing score assessment – Histopathological examination of mouse tissues was performed in a double-blind approach among three investigators, and their scores averaged. Qualitative assessments were based on epidermal and dermal maturation as outlined in FIG.14 and previously established protocols (Yates et al., Am J Pathol. Aug 2007;171(2):484-495; Yates et al., Wound Repair Regen. Jan-Feb 2009;17(1):34-41; Yates et al., Am J Pathol. Sep 2008;173(3):643-652). In short, the samples were scored on a scale of 0 to 4 for both epidermal and dermal layers of tissue. For epidermal maturation scoring: 0 = no epidermal migration, 1 = partial epidermal migration, 2 = complete epidermal migration, 3 = partial keratinization and an intact basement membrane, 4 = complete keratinization and normal epidermis. For dermal maturation scoring: 0 = no healing, 1 = inflammatory infiltration, 2 = granulation tissue present – fibroplasias and angiogenesis, 3 = collagen deposition replacing granulation tissue > 50%, 4 = complete replacement of granulation tissue and complete healing. Skin thickness measurements – H&E and MT sample images were analyzed using ImageJ line measurement tool to measure the thickness of the epidermal layer and dermal layer for each mouse specimen. The epidermal layers were measured from the stratum basale to the stratum granulosum (excluding the stratum corneum); and the dermal layer was measured form the top of the papillary layers to the bottom of the reticular layer. A total of 6 measurements per biological sample were scored for each layer. ^{8123-107870-02} Collagen quantification – Polarized PSR images were quantified using ImageJ version 1.53K. Each image was split into red, green, and blue channels, from which the red and green channels were selected. The isolated red and green channels then underwent thresholding and follow-up measurements to determine the total staining area for each collagen type. PSR birefringence under polarized light reveals tightly packed thick and long fibrils of type 1 collagen as either bright red-orange intense birefringence in tissue and thin short loose fibrils as yellow-green (Coelho et al., An Bras Dermatol. Jun 2018;93(3):415-418). The overall ratio of type 1 collagen to type III collagen was analyzed by comparing the representative staining results for either collagen type back to the original image for total collagen content. Collagen orientation and alignment – Polarized PSR images were quantified using ImageJ plug-in: OrientationJ version 2.0.5. Visual directional analysis using the color survey tool was performed with the following parameters: Hue was set for orientation, Saturation was set for coherency, and brightness was set to the original image (Puspoki et al., Adv Anat Embryol Cell Biol.2016;219:69-93). The OrientationJ distribution tool was used to create the distribution of orientation histograms to determine where patterns of alignment were within samples (Rezakhaniha et al., Biomech Model Mechanobiol. Mar 2012;11(3-4):461- 473). The OrientationJ Dominant Direction tool was used to determine the quantitative orientation measurement for coherency across the whole image (Fonck et al., Stroke. Jul 2009;40(7):2552-2556). Immunohistochemistry staining– Skin sample tissue sections (6 µm) were rehydrated and placed into citrate acid buffer at 95°C for 10 minutes and allowed to cool to room temperature for 1 hour. Samples were then washed in phosphate-buffered saline (PBS) and quenched with 3% hydrogen peroxide. Following additional washes in PBS, samples were blocked in 20% goat serum for 1 hour and subsequently incubated with primary antibodies diluted in blocking buffer overnight at 4ºC. Primary antibodies were used at the following dilutions: CD45 (1:100, Cat. No. ab10558, Abcam) and Col-IV (1:500, Cat. No. ab236640, Abcam). After primary antibody incubation, samples were washed in PBS and incubated in goat anti-rabbit HRP secondary antibody (1:2000, Cat. No. ab205718, Abcam) for 1 hour at room temperature. After final antibody incubations, samples were washed in PBS and then treated with ABC reagent (Cat. No. PK-6100, Vector Laboratories) for 30 minutes. Samples were then rewashed with PBS and developed with DAB reagent kit 27 (Cat. No. SK-4100, Vector laboratories), counterstained with H&E, clarified (Richard Alan Scientific), and dehydrated in ethanol and xylene. Samples were mounted (Cat. No. SP15-500, Fisher Scientific) and imaged using an Olympus Provis microscope. Image analysis was performed using Image J Colour Deconvolution 2 plug-in to acquire DAB positive staining area. The total DAB positive area was compared back to the total area of the original image to get a final percentage. Immunofluorescence staining – Skin sample tissue sections (6 µm) were rehydrated and placed into citrate acid buffer at 95°C for 10 minutes and allowed to cool to room temperature for 1 hour. Samples were then washed in PBS and quenched with 3% hydrogen peroxide. Following additional washes in PBS, samples were blocked in 20% goat serum for 1 hour and subsequently incubated with primary antibodies diluted in blocking buffer overnight at 4ºC. Primary antibodies were used at the following dilutions: CD31 (1:50, Cat. No. ab28364, Abcam) and Involucrin (1:500, Cat. No.924401, Biolegend). After primary ^{8123-107870-02} antibody incubation, samples were washed in PBS and incubated in goat anti-rabbit 488 secondary antibody (1:200, Cat. No. ab150077, Abcam) for 1 hour at room temperature in the dark. Samples were washed in PBS and mounted in Prolong Gold Antifade Mountant with DAPI (Cat. No. P36931, Invitrogen). Fluorescent images were obtained using an Olympus Provis microscope. Statistical Analysis Results for wound healing score assessment and PSR staining assessment were expressed as mean ± SD with at least a minimum of four mice per treatment group. Histological quantifications for skin layer thickness and immunohistological stains (CD31, CD45, Col-IV) were performed on five microscopic fields of each specimen and reported as mean ± SEM. Statistical differences between groups were determined by one-way ANOVA, followed by post-hoc Tukey HSD analysis using GraphPad Prism 9 software (GraphPad Software, San Diego, CA). Significance was claimed for P<0.05. Example 7: Growth factor therapy augments initial phases of healing Wounds made in the CXCR3-/- mice were treated 7 days after initial wounding using DCN or HB- EGF encapsulated in coacervate. These mice were then analyzed on day 14, during the later stages of the inflammation phase of wound healing (Wells et al., Matrix Biol. Jan 2016;49:25-36). Mice treated with CO + HB-EGF has increased epidermal closure compared to CO + DCN or CO only treated mice (FIG.11A- 11C). CO + HB-EGF treated mice exhibited complete epithelial cell migration in three of four mice, allowing for the early elimination of the eschar. An additional marker for determining epidermal maturation was used by examining a marker for keratinocyte cohesion, involucrin. In an early, less mature epidermis, the involucrin protein is localized in the cytoplasm of keratinocytes as exhibited in CO only, and CO + DCN treated mice (FIG.11D). However, in a more mature epidermis, keratinocytes have secreted the involucrin outside the cell to help form a protective boundary and allow the complete formation of the keratinized stratified epithelium as exhibited by the CO + HB-EGF mice (FIG.11D) (Eckert et al., J Invest Dermatol. May 1993;100(5):613-617). These results demonstrated that CO + HB-EGF treated mice had significantly faster epidermal wound healing than CO + DCN treated mice (FIG.11E). Upon examining the dermal layer of tissue, histological stains H&E and MT revealed a high amount of cell infiltrate within each treatment group (FIGS.11A, 11B). Staining for leucocyte common antigen (CD45) was used to assess differences in immune cell infiltrate (FIG.11G). However, no significant differences were found among treatment groups after quantification (FIG.11H). The thickness of the dermis was also measured (FIG.11F) but no significance was found. These findings showed no significant difference between treatment groups regarding the overall dermal wound healing score (FIG.11E). These findings indicate that the epidermal closure can be accelerated by upregulating the growth factor signaling early in wound healing. However, the dermal healing proceeds while introducing DCN, a healing 'stop' signaling, does not affect the inflammatory phases of wound healing. ^{8123-107870-02} Example 8: Modifying the matrix increased vascularization during tissue replacement Continuing onto the findings of delayed dermal maturation of CXCR -/- mice, it was observed whether any coacervate treatment group helped to improve outcomes during the tissue replacement phase of repair by examining outcomes at 30 days. At this point in the wound healing process, histological stains using H&E and MT reveal complete migration and stratification of the epidermal layer, including eliminating the eschar in all three treatment groups (FIGS.12A, 12B). Additional staining with involucrin showed a complete protective barrier signifying the completion of the stratified corneum in the epidermis in all three treatment groups (FIG.12F). The final stain of Col-IV revealing the formation of an intact basement membrane fully separating the epidermis from the dermis (FIG.12E), demonstrates that the epidermal layer has reached a total wound healing score of 4 in all three treatment groups (FIG.12C). Further histological examination of the dermal tissue layer did not reveal a significant difference, with all treatment groups averaging a wound healing score of 3 and the exact thickness measurement of roughly 0.50 mm (FIGS.12C, 12D). In the MT staining, the CO only mice appeared to have slightly less collagen than the other two treatment groups (FIG.12B). However, further quantification of collagen Col- 1/Col-III ratio and alignment using PSR stains revealed no significant differences (FIGS.15A-15D). Histological examination also revealed an overall decrease in cellularity compared to D14 samples (FIGS. 12A, 12B). The presence of immune cell infiltrate with CD45 was assessed but a significant difference was not observed among treatment groups (FIGS.15F, 15G). However, surprisingly, there was a significant increase in capillary formation of CO + DCN treated mice compared to CO only treated mice confirmed through CD31 and Col-IV staining (FIGS.12G, 12H, 15E). However, even with increased vascularity, this did not change the overall wound scoring during this phase of repair. Example 9: Coacervate with Decorin improves wound healing outcomes in the resolution phase CXCR3 knockout mice exhibit hypertrophic scarring by day 90 after the initial wound (Yates et al., Am J Pathol. Apr 2010;176(4):1743-1755); this was predicted to be the time point during wound resolution that 'stop' signals would exert their most significant effects. To this point, significantly improved wound healing scores were observed in mice treated with CO + DCN as compared to CO only mice (FIGS.13A- 13C). CO + DCN treated mice exhibited less overall cellularity within the dermal layer of tissue in addition to more organized collagen fibrils. Additionally, CO + DCN treated mice presented a significantly thinner epidermal and dermal wound thickness compared to CO only mice as these resolved back towards unwounded thicknesses (FIG.13D). CO + HB-EGF also exhibited a significantly higher dermal wound score over CO only mice but did not significantly change the overall thickness measurement for either the epidermal or dermal layers, suggesting that this treatment did not drive resolution. The collagen content and alignment of PSR staining was further assessed (FIG.13E). Using polarized light microscopy on PSR stained samples, the natural birefringence of collagen fibers allows for the evaluation of collagen organization and separation into either collagen type I displaying a red-orange color or collagen type III with a green-yellow color (FIG.13F) (Coelho et al., An Bras Dermatol. Jun ^{8123-107870-02} 2018;93(3):415-418). Upon quantifying collagen content, it was observed that the mice treated with CO + DCN had a significantly higher ratio of Col-1/Col-III compared to that of CO only treated mice, returning the collagen content ratio to that observed in unwounded skin samples (FIG.13G). Conversely, both CO only and HB-EGF treated mice had significantly lower ratios of Col-1/Col-III, suggesting these mouse populations are still in the process of turning over the remaining granulation tissue from the tissue replacement phase. The orientation of the collagen in the PSR stains was assessed next. Utilizing the ImageJ plug-in OrientationJ, the overall profile alignment of collagen was measured for an entire specimen as well as the overall coherency. First, the overall alignment of the collagen fibrils was observed using the color survey analysis tool, which allows pseudo coloring of the PSR images to hues that represent certain degrees of alignment (FIG.13H). This was further quantified in FIG.13I, to show the total distribution of all collagen fibrils relative to their degree of alignment. All treatment groups displayed a skewed bimodal distribution with one smaller peak around the -50 degree orientation mark and one larger peak around the +50 degree orientation mark. This bimodal skew is attributed to the loss of rete ridges in the papillary dermis after a full- thickness wound. CO + DCN treated mice exhibited the highest collagen alignment around the +50 degree orientation mark compared to the other two treatments groups. The second measure investigated was the overall coherency of the collagen fibrils within each image. Coherency measure is between 0 and 1, where 0 indicates complete isotropy and 1 indicate complete alignment (Rezakhaniha et al., Biomech Model Mechanobiol. Mar 2012;11(3-4):461-473). Similar to what was observed in the collagen alignment, CO + DCN treated mice exhibited the highest coherency rate compared to the two other groups while significantly higher than CO only treated mice (FIG.13). These results show that CO + DCN mice are further developed and more mature in their collagen content and alignment. To further examine differences in collagen fibril modification, high resolution PSR images at 100x magnification were analyzed using CTFIRE for overall fibril diameter and length (FIGS.16A-16B). CO + DCN-treated mice exhibited a significantly thicker diameter compared to only CO-treated mice (FIG.16C). Additionally, both CO + DCN and CO + HB-EGF were significantly longer than only CO-treated mice and were very similar to the unwounded control (FIG.16D). Altogether these results show that CO + DCN- treated mice are further developed and more mature in their collagen content and fibrillogenesis during the resolution phase of wound healing. It will be apparent that the precise details of the methods or compositions described may be varied or modified without departing from the spirit of the described aspects of the disclosure. We claim all such modifications and variations that fall within the scope and spirit of the claims below.
