Chimeric proteins comprising a hematopoietic growth factor and a flt3 agonist are useful for increasing hematopoietic cell production in mammals.

Description

flt3 Ligand Chimeric Proteins The present application is a Continuation-in-Part of 08/837,026 filed April 11, 1997 which is incorporated 5 herein by reference.

FIELD OF THE INVENTION The present invention relates to chimeric proteins or multi-functional hematopoietic receptor agonists, comprising a human flt3 agonist. These chimera proteins retain one or more activities of native flt3 ligand and the other component of the 15 chimera protein. The chimera protein may also show improved hematopoietic cell-stimulating activity or an activity not seen for flt3 ligand and the other factor when co-administered. The chimera protein may also show an improved activity profile which may 20 include reduction of undesirable biological activities associated with native flt3 ligand and/or have improved physical properties which may include increased solubility, stability and refold efficiency.

BACKGROUND OF THE INVENTION Colony stimulating factors which stimulate the differentiation and/or proliferation of bone marrow 30 cells have generated much interest because of their therapeutic potential for restoring depressed levels of hematopoietic stem cell-derived cells. Colony stimulating factors in both human and murine systems have been identified and distinguished according to 35 their activities. For example, granulocyte-CSF (G-CSF) and macrophage-CSF (M-CSF) stimulate the in vitro formation of neutrophilic granulocyte and Printed from Mimosa WO 98/46750 PCT/US98/075U 2 macrophage colonies, respectively while GM-CSF and interl,eukin-3 (IL-3) have broader activities and stimulate the formation of both macrophage, neutrophilic and eosinophilic granulocyte colonies.

Certain factors such as flt3 ligand are able to predominately affect stem cells.

Tyrosine kinase receptors are growth factor receptors that regulate the proliferation and differentiation of a number of cell. Certain tyrosine 10 kinase receptors function within the hematopoietic system. Flt3 (Roseate et al. , Oncogene, 6:1641-1650, 1991) and flk-2 (Matthews et al., Cell, 65:1143-1152, 1991) are forms of a tyrosine kinase receptor that is related to c-fms and c-kit receptors. The flk-2 and 15 flt3 receptors are similar in amino acid sequence and vary at two amino acid residues in the extracellular domain and diverge in a 31 amino acid segment located near the C-terminus.

Flt3 ligand is a hematopoietic growth factor which has the property of being able to regulate the growth and differentiation of hematopoietic progenitor and stem cells. Because of its ability to support the growth and proliferation of progenitor 25 cells, flt3 receptor agonists have potential for therapeutic use in treating hematopoietic disorders such as aplastic anemia and myelodysplastic syndromes. Additionally, flt3 receptor agonists will be useful in restoring hematopoietic cells to normal 30 amounts in those cases where the number of cells has been reduced due to diseases or to therapeutic treatments such as radiation and chemotherapy.

WO 94/28391 discloses the native flt3 ligand 35 protein sequence and a cDNA sequence encoding the flt3 ligand, methods of expressing flt3 ligand in a host cell transfected with the cDNA and methods of Printed from Mimosa 3 treating patients with a hematopoietic disorder using flt3 l,igand.

US Patent No. 5,554,512 is directed to human 5 flt3 ligand as an isolated protein, DNA encoding the flt3 ligand, host cells transfected with cDNAs encoding flt3 ligand and methods for treating patients with flt3 ligand.

WO 94/26891 provides mammalian flt3 ligands, including an isolate that has an insertion of 29 amino acids, and fragments there of.

The human blood-forming (hematopoietic) system 15 replaces a variety of white blood cells (including neutrophils, macrophages, and basophils/mast cells), red blood cells (erythrocytes) and clot-forming cells (megakaryocytes/platelets). The hematopoietic systems of the average male has been estimated to 20 produce on the order of 4.5 x 1011 granulocytes and erythrocytes every year, which is equivalent to an annual replacement of total body weight (Dexter et al., BioEssays, 2;154-158, 1985).

U.S. Patent 4,999,291 discloses DNA and methods for making G-CSF the disclosure of which is incorporated herein by reference in it entirety.

U.S. Patent 4,810,643 relates to DNA and methods 30 of making G-CSF and Cys to Ser substitution variants of G-CSF.

Kuga et al. (Biochem. + Biophys. Res. Comm.. 159:103-111, 1988) made a series of G-CSF variants to 35 partially define the structure-function relationship. Kuga et al. found that internal and C-terminal deletions abolished activity, while N-terminal Printed from Mimosa 4 deletions of up to 11 amino acids and amino acid substitutions at positions 1, 2 and 3 were active.

Watanabe et al. (Anal. Biochem. 195:38-44, 1991) 5 made a variant to study G-CSF receptor binding in which amino acids 1 and 3 were changed to Tyr for radioiodination of the protein. Watanabe et al. found this Tyr1, Tyr^ G-CSF variant to be active.

Erythropoietin is a naturally-occurring glycoprotein hormone with a molecular weight that was first reported to be approximately 39,000 daltons (T. Miyaki et al., J. Biol. Chem. 252:5558-5564 (1977)). The mature hormone is 166 amino acids long and the 15 "prepro" form of the hormone, with its leader peptide, is 193 amino acids long (F. Lin, U.S. Patent No. 4,703,008). The mature hormone has a molecular weight, calculated from its amino acid sequence, of 18,399 daltons (K. Jacobs et al., Nature 313:806-810 20 (1985); J. K. Browne et al.. Cold Spring Harbor Symp. Quant. Biol. 5:1693-702 (1986).

The first mutant erythropoietins (i.e., erythropoietin analogs), prepared by making amino 25 acid substitutions and deletions, have demonstrated reduced or unimproved activity. As described in U.S. Patent NO. 4,703,008, replacement of the tyrosine residues at positions 15, 40 and 145 with phenylalanine residues, replacement of the cysteine 30 residue at position 7 with an histidine, substitution of the proline at position 2 with an asparagine, deletion of residues 2-6, deletion of residues 163-166, and deletion of residues 27-55 does not result in an apparent increase in biological activity. The 35 Cys7-to-His7 mutation eliminates biological activity. A series of mutant erythropoietins with a single amino acid substitution at asparagine residues 24, 3 8 Printed from Mimosa or 83 show severely reduced activity (substitution at position 24) or exhibit rapid intracellular degradation and apparent lack of secretion (substitution at residue 38 or 183). Elimination of 5 the O-linked glycosylation site at serinel26 results in rapid degradation or lack of secretion of the erythropoietin analog (S. Dube et al., J. Biol. Chem. 33:17516-17521 (1988). These authors conclude that glycosylation sites at residues 38, 83 and 12 6 are 10 required for proper secretion and that glycosylation sites located at residues 24 and 38 may be involved in the biological activity of mature erythropoietin.

Deglycosylated erythropoietin is fully active in 15 in vitro bioassays (M. S. Dorsdal et al., Endocrinology 116:2293-2299 (1985); U.S. Patent No. 4,703,008; E. Tsuda et al., Eur J. Biochem. 266:20434-20439 (1991). However, glycosylation of erythropoietin is widely accepted to play a critical 20 role in the in vivo activity of the hormone (P. H..

Lowy et al., Nature 185:102-105 (1960); E. Goldwasser and C. K. H.. Kung, Ann. N.Y. Acad. Science 149:49-53 (1968) ,- w. A. Lukowsky and R. H. . Painter, Can. J. Biochem. :909-917 (1972); D.W. Briggs et al., Amer. 25 J. Phys. 201:1385-1388 (1974); J.C. Schooley, Exp.

Hematol. 13:994-998; N. Imai et al., Eur. J. Biochem. 194:457-462 (1990); M.S. Dordal et al., Endocrinology 116:2293-2299 (1985); E. Tsuda et al., Eur. J. Biochem. 188:405-411 (1990); U.S. Patent No. 30 4,703,008; J.K. Brown et al.. Cold Spring Harbor Symposia on Quant. Biol. 51:693-702 (1986); and K. Yamaguchi et al., J. Biol. Chem. 266:20434-20439 (1991). The lack if in vivo biological activity of deglycosylated analogs of erythropoietin is 35 attributed to a rapid clearance of the deglycosylated hormone from the circulation of treated animals.

This view is supported by direct comparison of the Printed from Mimosa WO 98/46750 PCT/US98/07511 6 plasma half-life of glycosylated and deglycosylated erythropoietin (J.C. Spivak and B.B. Hoyans, Blood 73:90-99 (1989), and M.N. Fukuda, et al., Blood 73:84-89 (1989) .

Oligonucleotide-directed mutagenesis of erythropoietin glycosylation sites has effectively probed the function of glycosylation but has failed, as yet, to provide insight into an effective strategy 10 for significantly improving the characteristics of the hormone for therapeutic applications.

A series of single amino acid substitution or deletion mutants have been constructed of 15 erythropoietin, involving amino acid residues 15, 24, 49, 76, 78, 83, 143, 145, 160, 162, 163, 164, 165 and 166. In these mutants are altered the carboxy terminus, the glycosylation sites, and the tyrosine residues of erythropoietin. The mutants have been 20 administered to animals while monitoring hemoglobin, hematocrit and reticulocyte levels (EP No. 0 409 113). While many of these mutants retain in vivo biological activity, none show a significant increase in their ability to raise hemoglobin, hematocrit or 25 reticulocyte (the immediate precursor of an erythrocyte) levels when compared to native erythropoietin.

Another set of mutants has been constructed to 30 probe the function of residues 99-119 (domain 1) and residues 111-129 (domain 2) (Y. Chern et al., Eur. J. Biochem. 202:225-230 (1991)). The domain 1 mutants are rapidly degraded and inactive in an in vitro bioassay while the domain 2 mutants, at best, retain 3 5 in vitro activity. These mutants also show no enhanced in vivo biological activity as compared to wild-type, human erythropoietin. These authors Printed from Mimosa 7 conclude that residues 99-119 play a critical role in the structure of erythropoietin.

The human erythropoietin molecule contains two 5 disulfide bridges, one linking the cysteine residues at positions 7 and 161, and a second connecting cysteines at positions 29 and 33 (P.H. Lai et al., J. Biol. Chem. 261:3116-3121 (1986)). Oligonucleotide-directed mutagenesis has been used to probe the 10 function of the disulfide bridge linking cysteines 29 and 33 in human erythropoietin. The cysteine at position 3 3 has been converted to a proline residue, which, mimics the structure of murine erythropoietin at this residue. The resulting mutant has greatly 15 reduced in vitro activity. The loss of activity is so severe that the authors conclude that the disulfide bridge between residues 29 and 33 is essential for erythropoietin function (F.K. Lin, Molecular and Cellular Aspects of Erythropoietin and 20 Erythropoiesis, pp. 23-36, ed. I.N. Rich, Springer-Verlag, Berlin (1987)).

U.S. Patent No. 4,703,008 by Lin, F-K. (hereinafter referred to as "the '008 patent") 25 speculates about a wide variety of modifications of EPO, including addition, deletion, and substitution analogs of EPO. The '008 patent does not indicate that any of the suggested modifications would increase biological activity per se, although it is 30 stated that deletion of glycosylation sites might increase the activity of EPO produced in yeast (See the '008 patent at column 37, lines 25-28). Also, the '008 patent speculates that EPO analogs which have one or more tyrosine residues replaced with 35 phenylalanine may exhibit an increased or decreased receptor binding affinity.

Printed from Mimosa 8 Australian Patent Application No. AU-A-59145/90 by Filpi, M et al. also discusses a number of modified EPO proteins (EPO muteins). It is generally speculated that the alteration of amino acids 10-55, 5 70-85, and 130-166 of EPO. In particular, additions of positively charged basic amino acids in the carboxyl terminal region are purported to increase the biological activity of EPO.

U.S. Patent No. 4,835,260 by Shoemaker, C.B. discusses modified EPO proteins with amino acid substitutions of the methionine at position 54 and asparagine at position 38. Such EPO muteins are thought to have improved stability but are not 15 proposed to exhibit any increase in biological activity relative to wild type EPO.

WO 91/05867 discloses analogs of human erythropoietin having a greater number of sites for 20 carbohydrate attachment than human erythropoietin, such as EPO (Asn^^) , EPO (Asn12^, Ser12"?) , EPO (Thr125), and EPO (Pro124, Thr125).

WO 94 /24160 discloses erythropoietin muteins 25 which have enhanced activity, specifically amino acid substitutions at positions 20, 49, 73, 140, 143, 146, 147 and 154.

WO 94/25055 discloses erythropoietin analogs, 3 0 including EPO (X^3, Cys1-^, des-Arg1^) an(j ^PO (Cys139/ des-Arg1^) .

Stem cell factor has the ability to stimulate growth of early hematopoietic progenitors which are 35 capable of maturing to erythroid, megakaryocyte, granulocyte, lymphocyte and macrophage cells. Stem cell factor treatment of mammals results in absolute Printed from Mimosa 9 increases in hematopoietic cells of both the myeloid and lymphoid cells.

EP 0 423 980 discloses novel stem cell factor 5 (SCF) polypeptides including SCF1"148, SCF1"157, SCF1"160, SCF1"161, SCF1"162, SCF1"164, SCF1"165, SCF1"183, SCF1"185, SCF1" 188 SCF1"248 U.S. 4,877,729 and U.S. 4,959,455 disclose human 10 IL-3 and gibbon IL-3 cDNAs and the protein sequences for which they code. The hIL-3 disclosed has serine rather than proline at position 8 in the protein sequence.

International Patent Application (PCT) WO 15 88/00598 discloses gibbon- and human-like IL-3. The hIL-3 contains a Ser8 -> Pro8 replacement.

Suggestions are made to replace Cys by Ser, thereby breaking the disulfide bridge, and to replace one or more amino acids at the glycosylation sites. 20 U.S. 4,810,643 discloses the DNA sequence encoding human G-CSF.

WO 91/02754 discloses a fusion protein comprised of GM-CSF and IL-3 which has increased biological activity compared to GM-CSF or IL-3 alone. Also 25 disclosed are nonglycosylated IL-3 and GM-CSF analog proteins as components of the multi-functional hematopoietic receptor agonist.

WO 92/04455 discloses fusion proteins composed of IL-3 fused to a lymphokine selected from the group 30 consisting of IL-3, IL-6, IL-7, IL-9, IL-11, EPO and G-CSF.

WO 95/21197 and WO 95/21254 disclose fusion proteins capable of broad multi-functional hematopoietic properties.

GB 2,285,446 relates to the c-mpl ligand (thrombopoietin) and various forms of thrombopoietin which are shown to influence the replication, Printed from Mimosa differentiation and maturation of megakaryocytes and megakaryocytes progenitors which may be used for the treatment of thrombocytopenia.

EP 675,201 Al relates to the c-mpl ligand 5 (Megakaryocyte growth and development factor (MGDF), allelic variations of c-mpl ligand and c-mpl ligand attached to water soluble polymers such as polyethylene glycol.

WO 95/21920 provides the murine and human c-mpl 10 ligand and polypeptide fragments thereof. The proteins are useful for in vivo and ex vivo therapy for stimulating platelet production.

Summary of the Invention The present invention encompasses recombinant chimeric proteins comprising a flt3 agonist and 20 another factor. The other factor may be a colony stimulating factor (CSF), cytokine, lymphokine, interleukin, hematopoietic growth factor which include but are not limited to GM-CSF, c-mpl ligand (also known as TPO or MGDF), M-CSF, erythropoietin 25 (EPO), IL-1, IL-4, IL-2, IL-3, IL-5, IL 6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, IL-15, LIF, flt3 ligand, human growth hormone, B-cell growth factor, B-cell differentiation factor, eosinophil differentiation factor, stem cell factor (SCF) also 30 known as steel factor or c-kit ligand, stem cell growth factor (SCGF)(Hiraoka, A. et al. Proc. Natl. Acad. Sci USA 94:7577-7582, 1997) and Stromal Cell-derived Factor 1 (SDF-1) (Bleul, C.C. et al., J. Exp. Med 184:1101-1109, 1996) , (herein collectively 35 referred to as "hematopoietic growth factors". The chimera proteins can also be co-administered or sequentially administered with one or more additional colony stimulating factor(s), cytokine(s), Printed from Mimosa 11 lymphokine(s), interleukin(s}, hematopoietic growth factor(s) which include but are not limited to GM-CSF, c-mpl ligand (also known as TPO or MGDF), M-CSF, erythropoietin (EPO), IL-1, IL-4, IL-2, IL-3, IL-5, 5 IL 6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, IL-15, LIF, human growth hormone, B-cell growth factor, B-cell differentiation factor, eosinophil differentiation factor, stem cell factor (SCF) also known as steel factor or c-kit ligand, SCGF and SDF-1 10 (herein collectively referred to "hematopoietic growth factors". These co-administered mixtures may be characterized by having the usual activity of both of the peptides or the mixture may be further characterized by having a biological or physiological 15 activity greater than simply the additive function of the presence of the G-CSF receptor agonists or the second hematopoietic growth factor alone. The chimeric protein may also provide an enhanced effect on the activity or an activity different from that 20 expected by the presence of the flt3 ligand or the second colony stimulating factor. The chimeric protein may also have an improved activity profile which may include reduction of undesirable biological activities associated with native human flt3.

Detailed Description of the Invention The present invention encompasses multifunctional hematopoietic receptor agonists or 30 chimeric proteins formed from covalently linked polypeptides, each of which may act through a different and specific cell receptor to initiate complementary biological activities. Hematopoiesis requires a complex series of cellular events in which 35 stem cells generate continuously into large populations of maturing cells in all major lineages. There are currently at least 20 known regulators with Printed from Mimosa 12 hematopoietic proliferative activity. Most of these proliferative regulators can only stimulate one or another type of colony formation in vitro, the precise pattern of colony formation stimulated by 5 each regulator is quite distinctive. No two regulators stimulate exactly the same pattern of colony formation, as evaluated by colony numbers or, more importantly, by the lineage and maturation pattern of the cells making up the developing 10 colonies. Proliferative responses can most readily be analyzed in simplified in vitro culture systems.

Three quite different parameters can be distinguished: alteration in colony size, alteration in colony numbers and cell lineage. Two or more 15 factors may act on the progenitor cell, inducing the formation of larger number of progeny thereby increasing the colony size. Two or more factors may allow increased number of progenitor cells to proliferate either because distinct subsets of 20 progenitors cells exist that respond exclusively to one factor or because some progenitors require stimulation by two or more factors before being able to respond. Activation of additional receptors on a cell by the use of two or more factors is likely to 25 enhance the mitotic signal because of coalescence of initially differing signal pathways into a common final pathway reaching the nucleus (Metcalf, Nature 339:27, 1989). Other mechanisms could explain synergy. For example, if one signaling pathway is 30 limited by an intermediate activation of an additional signaling pathway which is caused by a second factor, then this may result in a super additive response. In some cases, activation of one receptor type can induce an enhanced expression of 35 other receptors (Metcalf, Blood 82:3515-3523, 1993). Two or more factors may result in a different pattern of cell lineages than from a single factor. The use Printed from Mimosa 13 of multi-functional hematopoietic receptor agonists may have a potential clinical advantage resulting from a proliferative response that is not possible by any single factor.

The receptors of hematopoietic and other growth factors can be grouped into two distinct families of related proteins: (1) tyrosine kinase receptors, including those for epidermal growth factor, M-CSF (Sherr, Blood 75:1, 1990) and SCF (Yarden et al., 10 EMBO J. 6:3341, 1987): and (2) hematopoietic receptors, not containing a tyrosine kinase domain, but exhibiting obvious homology in their extracellular domain (Bazan, PNAS USA 87:6934-6938, 1990) . Included in this latter group are 15 erythropoietin (EPO) (D'Andrea et al., Cell 57:277, 1989), GM-CSF (Gearing et al., EMBO J. 8:3667, 1989), IL-3 (Kitamura et al., Cell 66:1165, 1991), G-CSF (Fukunaga et al., J. Bio. Chem. 265:14008-15, 1990), IL-4 (Harada et al., PNAS USA 87:857, 1990), IL-5 20 (Takaki et al., EMBO J. 9:4367, 1990), IL-6 (Yamasaki et al. , Science 241:825, 1988), IL-7 (Goodwin et al., Cell 60:941-51, 1990), LIF (Gearing et al., EMBO J. 10:2839, 1991) and IL-2 (Cosman et al., Mol-Immunol. 23: 935-94, 1986). Most of the latter group of 25 receptors exists in a high-affinity form as heterodimers. After ligand binding, the specific a-chains become associated with at least one other receptor chain (p-chain, ychain) • Many of these factors share a common receptor subunit. The a-chains 30 for GM-CSF, IL-3 and IL-5 share the same p-chain (Kitamura et al., Cell 66:1165, 1991), Takaki et al., EMBO J. 10:2 833-8, 1991) and receptor complexes for IL-6, LIF and IL-11 share a common p-chain (gpl30) (Taga et al., Cell 58:573-81, 1989; Gearing et al., 35 Science 255:1434-7, 1992). The receptor complexes of IL-2, IL-4, IL-7, IL-9 and IL-15 share a common y-chain (Kondo et al., Science 262:1874, 1993; Russell Printed from Mimosa 14 et al., Science 266: 1042-1045, 1993; Noguchi et al.. Science 262:1877, 1993; Giri et al., EMBO J. 13:2822-2830, 1994).

The use of a multiply acting hematopoietic 5 factor may also have a potential advantage by reducing the demands placed on factor-producing cells and their induction systems. If there are limitations in the ability of a cell to produce a factor, then by lowering the required concentrations of each of the 10 factors, and using them in combination may usefully reduce demands on the factor-producing cells. The use of a multiply acting hematopoietic factor may lower the amount of the factors that would be needed, probably reducing the likelihood of adverse side-15 effects.

Novel compounds of this invention are represented by a formula selected from the group consisting of: R1-L1-R2, R2-L1-R1, R1-R2. and R2-R1 Where Hi is a flt3 agonist and R2 is a hematopoietic growth factor. Preferably R2 is a hematopoietic growth factor with a different but 25 complementary activity than Ri. By complementary activity is meant activity which enhances or changes the response to another cell modulator. The Ri polypeptide is joined either directly or through a linker segment to the R2 polypeptide. The term 30 "directly" defines multi-functional hematopoietic receptor agonists in which the polypeptides are joined without a peptide linker. Thus Li represents a chemical bond or polypeptide segment to which both Ri and R2 are joined in frame, most commonly Li is a 35 linear peptide to which RI and R2 are joined by amide bonds linking the carboxy terminus of Ri to the amino terminus of Li and carboxy terminus of Li to the Printed from Mimosa WO 98/46750 PCT/US98/07511 amino terminus of R2- By "joined in frame" is meant that there is no translation termination or disruption between the reading frames of the DNA encoding Ri and R2- A non-exclusive list of other growth factors, i.e. colony stimulating factors (CSFs), are cytokines, lymphokines, interleukins, hematopoietic growth factors which can be joined to Ri include GM-10 CSF, G-CSF, c-mpl ligand (also known as TPO or MGDF), M-CSF, erythropoietin (EPO), IL-1, IL-4, IL-2, IL-3, IL-5, IL 6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, IL-15, LIF, flt3 ligand, human growth hormone, B-cell growth factor, B-cell differentiation factor, 15 eosinophil differentiation factor, stem cell factor (SCF) also known as steel factor or c-kit ligand IL-12. Additionally, this invention encompasses the use of modified Ri or R2 molecules or mutated or modified DNA sequences encoding these Ri or R2 molecules. A 20 "c-mpl ligand variant" is defined an c-mpl ligand molecule which has amino acid substitutions and/or portions of c-mpl ligand deleted, disclosed in United States Application Serial Number 08/383,035 as well as other variants known in the art. A "G-CSF variant" 25 is defined an G-CSF molecule which has amino acid substitutions and/or portions of G-CSF deleted, as disclosed herein, as well as other variants known in the art. Preferably, R2 is G-CSF, GM-CSF, c-mpl ligand or EPO.

The linking group (Li) is generally a polypeptide of between 1 and 500 amino acids in length. The linkers joining the two molecules are preferably designed to (1) allow the two molecules to 35 fold and act independently of each other, (2) not have a propensity for developing an ordered secondary structure which could interfere with the functional Printed from Mimosa 16 domains of the two proteins, (3) have minimal hydrophobic characteristics which could interact with the functional protein domains and (4) provide steric separation of Ri and R2 such that Ri and R2 could 5 interact simultaneously with their corresponding receptors on a single cell. Typically surface amino acids in flexible protein regions include Gly, Asn and Ser. Virtually any permutation of amino acid sequences containing Gly, Asn and Ser would be 10 expected to satisfy the above criteria for a linker sequence. Other neutral amino acids, such as Thr and Ala, may also be used in the linker sequence. Additional amino acids may also be included in the 41inkers due to the addition of unique restriction 15 sites in the linker sequence to facilitate construction of the multi-functional hematopoietic receptor agonists.

Preferred Li linkers of the present invention include sequences selected from the group of 20 formulas: (Gly3Ser)n (SEQ IDNO-.l), (Gly4Ser)n (SEQ ID NO:2) , (Gly5Ser)n (SEQ ID NO:3), (GlynSer)n (SEQ ID NO:4) or (AlaGlySer)n (SEQ ID NO:5), where n is an integer (collectively referred to herein as "GlySer" 25 linkers).

One example of a highly-flexible linker is the glycine and serine-rich spacer region present within the pill protein of the filamentous bacteriophages, e.g. bacteriophages M13 or fd (Schaller et al., PNAS 30 USA 72: 737-741, 1975). This region provides a long, flexible spacer region between two domains of the pill surface protein. The spacer region consists of the amino acid sequence: 3 5 GlyGlyGlySerGlyGlyGlySerGlyGlyGlySerGluGlyGlyGlySerGlu GlyGlyGlySerGluGlyGlyGlySerGluGlyGlyGlySerGlyGlyGlySer (SEQ ID NO:6).

Printed from Mimosa 17 The present invention also includes linkers in which an endopeptidase recognition sequence is included. Such a cleavage site may be valuable to 5 separate the individual components of the multifunctional hematopoietic receptor agonist to determine if they are properly folded and active in vitro. Examples of various endopeptidases include, but are not limited to, plasmin, enterokinase, 10 kallikrein, urokinase, tissue plasminogen activator, clostripain, chymosin, collagenase, Russell's viper venom protease, postproline cleavage enzyme, V8 protease. Thrombin and factor Xa.

Peptide linker segments from the hinge region of 15 heavy chain immunoglobulins IgG, IgA, IgM, IgD or IgE provide an angular relationship between the attached polypeptides. Especially useful are those hinge regions where the cysteines are replaced with serines. Preferred linkers of the present invention 20 include sequences derived from murine IgG gamma 2b hinge region in which the cysteines have been changed to serines (Bell et al. US Patent 4,936,233). These linkers may also include an endopeptidase cleavage site. Examples of such linkers include the following 25 sequences: IleSerGluProSerGlyProIleSerThrlleAsnProSerProProSerLys GluSerHisLysSerPro (SEQ ID NO : 7 ) , and 3 0 IleGluGlyArglleSerGluProSerGlyProIleSerThrlleAsnProSer ProProSerLysGluSerHisLysSerPro (SEQ ID NO : 8 ) (collectively referred to herein as "IgG2b" linkers).

The present invention is, however, not limited 3 5 by the form, size or number of linker sequences employed and the only requirement of the linker is that functionally it does not interfere with the Printed from Mimosa 18 folding and function of the individual molecules of the multi-functional hematopoietic receptor agonist.

Hematopoietic growth factors can be 5 characterized by their ability to stimulate colony formation by human hematopoietic progenitor cells. The colonies formed include erythroid, granulocyte, megakaryocyte, granulocytic macrophages and mixtures thereof. Many of the hematopoietic growth factors 10 have demonstrated the ability to restore bone marrow function and peripheral blood cell populations to therapeutically beneficial levels in studies performed initially in primates and subsequently in humans. Many or all of these biological activities 15 of hematopoietic growth factors involve signal transduction and high affinity receptor binding. Multi-functional hematopoietic receptor agonists of the present invention may exhibit useful properties such as having similar or greater biological activity 20 when compared to a single factor or by having improved half-life or decreased adverse side effects, or a combination of these properties.

Multi-functional hematopoietic receptor agonists 25 which have little or no agonist activity maybe useful as antagonists, as antigens for the production of antibodies for use in immunology or immunotherapy, as genetic probes or as intermediates used to construct other useful hIL-3 muteins.

The present invention also includes the DNA sequences which code for the multi-functional hematopoietic receptor agonist proteins, DNA sequences which are substantially similar and perform 35 substantially the same function, and DNA sequences which differ from the DNAs encoding the multifunctional hematopoietic receptor agonists of the Printed from Mimosa 19 invention only due to the degeneracy of the genetic code. Also included in the present invention are the oligonucleotide intermediates used to construct the mutant DNAs and the polypeptides coded for by these 5 oligonucleotides.

Genetic engineering techniques now standard in the art (United States Patent 4,935,233 and Sambrook et al., "Molecular Cloning A Laboratory Manual", Cold 10 Spring Harbor Laboratory, 1989) may be used in the construction of the DNA sequences encoding flt3 ligand, EPO, G-CSF, GM-CSF, other hematopoietic growth factors and the chimeric proteins of the present invention. One such method is cassette 15 mutagenesis (Wells et al., Gene 34:315-323, 1985) in which a portion of the coding sequence in a plasmid is replaced with synthetic oligonucleotides that encode the desired amino acid substitutions in a portion of the gene between two restriction sites. 20 Pairs of complementary synthetic oligonucleotides encoding the desired gene can be made and annealed to each other. The DNA sequence of the oligonucleotide would encode sequence for amino acids of desired gene with the exception of those substituted and/or 25 deleted from the sequence.

Plasmid DNA can be treated with the chosen restriction endonucleases then ligated to the annealed oligonucleotides. The ligated mixtures can be used to transform competent bacterial cells such 30 as E. coli strain JM101 resistance to an appropriate antibiotic. Single colonies can be picked and the plasmid DNA examined by restriction analysis and/or DNA sequencing to identify plasmids with the desired genes.

Cloning of the DNA sequences of the novel multifunctional hematopoietic agonists wherein at least one of the with the DNA sequence of the other Printed from Mimosa WO 98/46750 PCT/US98/07511 hematopoietic growth factor may be accomplished by the use of intermediate vectors. Alternatively one gene can be cloned directly into a vector containing the other gene. Linkers and adapters can be used for 5 joining the DNA sequences, as well as replacing lost sequences, where a restriction site was internal to the region of interest. Thus genetic material (DNA) encoding one polypeptide, peptide linker, and the other polypeptide is inserted into a suitable 10 expression vector which is used to transform bacteria, yeast, insect cells or mammalian cells. The transformed organism is grown and the protein isolated by standard techniques. The resulting product is therefore a new protein which has a 15 hematopoietic growth factor joined by a linker region to a second colony stimulating factor.

Another aspect of the present invention provides plasmid DNA vectors for use in the expression of these novel multi-functional hematopoietic receptor 20 agonists. These vectors contain the novel DNA sequences described above which code for the novel polypeptides of the invention. Appropriate vectors which can transform microorganisms capable of expressing the multi-functional hematopoietic 25 receptor agonists include expression vectors comprising nucleotide sequences coding for the multifunctional hematopoietic receptor agonists joined to transcriptional and translational regulatory sequences which are selected according to the host 30 cells used.

Vectors incorporating modified sequences as described above are included in the present invention and are useful in the production of the multifunctional hematopoietic receptor agonist 35 polypeptides. The vector employed in the method also contains selected regulatory sequences in operative association with the DNA coding sequences of the Printed from Mimosa 21 invention and which are capable of directing the replication and expression thereof in selected host cells.

As another aspect of the present invention, 5 there is provided a method for producing the novel multi-functional hematopoietic receptor agonists. The method of the present invention involves culturing suitable cells or cell line, which has been transformed with a vector containing a DNA sequence 10 coding for expression of a novel multi-functional hematopoietic receptor agonist. Suitable cells or cell lines may be bacterial cells. For example, the various strains of E. coli are well-known as host cells in the field of biotechnology. Examples of 15 such strains include E. coli strains JM101 (Yanish-Perron et al. Gene 33: 103-119, 1985) and MON105 (Obukowicz et al., Applied Environmental Microbiology 58: 1511-1523, 1992). Also included in the present invention is the expression of the multi-functional 20 hematopoietic receptor agonist protein utilizing a chromosomal expression vector for E. coli based on the bacteriophage Mu (Weinberg et al. , Gene 126: 25-33, 1993) . Various strains of B. subtilis may also be employed in this method. Many strains of yeast 25 cells known to those skilled in the art are also available as host cells for expression of the polypeptides of the present invention. When expressed in the E. coli cytoplasm, the gene encoding the multi-functional hematopoietic receptor agonists 30 of the present invention may also be constructed such that at the 5' end of the gene codons are added to -2 -1 -1 encode Met -Ala - or Met at the N-termmus of the protein. The N termini of proteins made in the cytoplasm of E. coli are affected by post- translational processing by methionine aminopeptidase (Ben Bassat et al., J. Bac. 169:751-757, 1987) and possibly by other peptidases so that upon expression Printed from Mimosa 22 the methionine is cleaved off the N-terminus. The multirfunctional hematopoietic receptor agonists of the present invention may include multi-functional hematopoietic receptor agonist polypeptides having -1 -1 -2 -1 Met , Ala or Met -Ala at the N-terminus. These mutant multi-functional hematopoietic receptor agonists may also be expressed in E. coli by fusing a secretion signal peptide to the N-terminus. This signal peptide is cleaved from the polypeptide as 10 part of the secretion process.

Also suitable for use in the present invention are mammalian cells, such as Chinese hamster ovary cells (CHO). General methods for expression of foreign genes in mammalian cells are reviewed in 15 Kaufman, R. J., 1987) Genetic Engineering, Principles and Methods, Vol. 9, J. K. Setlow, editor, Plenum Press, New York. An expression vector is constructed in which a strong promoter capable of functioning in mammalian cells drives transcription of a eukaryotic 20 secretion signal peptide coding region, which is translationally joined to the coding region for the multi-functional hematopoietic receptor agonist. For example, plasmids such as pcDNA I/Neo, pRc/RSV, and pRc/CMV (obtained from Invitrogen Corp., San Diego, 25 California) can be used. The eukaryotic secretion signal peptide coding region can be from the gene itself or it can be from another secreted mammalian protein (Bayne, M. L. et al., Proc. Natl. Acad. Sci. USA 84: 2638-2642, 1987). After construction of the 30 vector containing the gene, the vector DNA is transfected into mammalian cells. Such cells can be, for example, the C0S7, HeLa, BHK, CHO, or mouse L lines. The cells can be cultured, for example, in DMEM media (JRH Scientific). The polypeptide 35 secreted into the media can be recovered by standard biochemical approaches following transient expression for 24 - 72 hours after transfection of the cells or Printed from Mimosa 23 after establishment of stable cell lines following selection for antibiotic resistance. The selection of suitable mammalian host cells and methods for transformation, culture, amplification, screening and 5 product production and purification are known in the art. See, e.g., Gething and Sambrook, Nature, 293:620-625, 1981), or alternatively, Kaufman et al, Mol. Cell. Biol., 5(7):1750-1759, 1985) or Howley et al., U.S. Pat. No. 4,419,446. Another suitable 10 mammalian cell line is the monkey COS-1 cell line. A similarly useful mammalian cell line is the CV-1 cell line.

Where desired, insect cells may be utilized as host cells in the method of the present invention. 15 See, e.g., Miller et al. , Genetic Engineering, 8:277-298 (Plenum Press 1986) and references cited therein. In addition, general methods for expression of foreign genes in insect cells using Baculovirus vectors are described in: Summers, M. D. and Smith, 20 G. E. , 1987) - A manual of methods for Baculovirus vectors and insect cell culture procedures, Texas Agricultural Experiment Station Bulletin No. 1555. An expression vector is constructed comprising a Baculovirus transfer vector, in which a strong 25 Baculovirus promoter (such as the polyhedron promoter) drives transcription of a eukaryotic secretion signal peptide coding region, which is translationally joined to the coding region for the multi-functional hematopoietic receptor agonist 30 polypeptide. For example, the plasmid pVLl392 (obtained from Invitrogen Corp., San Diego, California) can be used. After construction of the vector carrying the gene encoding the multifunctional hematopoietic receptor agonist 3 5 polypeptide, two micrograms of this DNA is co- transfected with one microgram of Baculovirus DNA (see Summers & Smith, 1987) into insect cells, strain Printed from Mimosa WO 98/46750 PCT/US98/07511 24 SF9. Pure recombinant Baculovirus carrying the multi-functional hematopoietic receptor agonist is used to infect cells cultured, for example, in Excell 401 serum-free medium (JRH Biosciences, Lenexa, 5 Kansas). The multi-functional hematopoietic receptor agonist secreted into the medium can be recovered by standard biochemical approaches. Supernatants from mammalian or insect cells expressing the multifunctional hematopoietic receptor agonist protein can 10 be first concentrated using any of a number of commercial concentration units.

The multi-functional hematopoietic receptor agonists of the present invention may be useful in 15 the treatment of diseases characterized by decreased levels of either myeloid, erythroid, lymphoid, or megakaryocyte cells of the hematopoietic system or combinations thereof. In addition, they may be used to activate mature myeloid and/or lymphoid cells. 20 Among conditions susceptible to treatment with the polypeptides of the present invention is leukopenia, a reduction in the number of circulating leukocytes (white cells) in the peripheral blood. Leukopenia may be induced by exposure to certain viruses or to 25 radiation. It is often a side effect of various forms of cancer therapy, e.g., exposure to chemotherapeutic drugs, radiation and of infection or hemorrhage. Therapeutic treatment of leukopenia with these multi-functional hematopoietic receptor 30 agonists of the present invention may avoid undesirable side effects caused by treatment with presently available drugs.

The multi-functional hematopoietic receptor agonists of the present invention may be useful in 35 the treatment of neutropenia and, for example, in the treatment of such conditions as aplastic anemia, cyclic neutropenia, idiopathic neutropenia, Chediak- Printed from Mimosa Higashi syndrome, systemic lupus erythematosus (SLE), leukemia, myelodysplastic syndrome and myelofibrosis.

The multi-functional hematopoietic receptor agonist of the present invention may be useful in the 5 treatment or prevention of thrombocytopenia.

Currently the only therapy for thrombocytopenia is platelet transfusion which are costly and carry the significant risks of infection (HIV, HBV) and alloimunization. The multi-functional hematopoietic 10 receptor agonist may alleviate or diminish the need for platelet transfusion. Severe thrombocytopenia may result from genetic defects such as Fanconi's Anemia, . Wiscott-Aldrich, or May Hegglin syndromes. Acquired thrombocytopenia may result from auto- or allo-15 antibodies as in Immune Thrombocytopenia Purpura, Systemic Lupus Erythromatosis, hemolytic anemia, or fetal maternal incompatibility. In addition, splenomegaly, disseminated intravascular coagulation, thrombotic thrombocytopenic purpura, infection or 20 prosthetic heart valves may result in thrombocytopenia. Severe thrombocytopenia may also result from chemotherapy and/or radiation therapy or cancer. Thrombocytopenia may also result from marrow invasion by carcinoma, lymphoma, leukemia or 25 fibrosis.

The multi-functional hematopoietic receptor agonists of the present invention may be useful in the mobilization of hematopoietic progenitors and 30 stem cells in peripheral blood. Peripheral blood derived progenitors have been shown to be effective in reconstituting patients in the setting of autologous marrow transplantation. Hematopoietic growth factors including G-CSF and GM-CSF have been 3 5 shown to enhance the number of circulating progenitors and stem cells in the peripheral blood. This has simplified the procedure for peripheral stem Printed from Mimosa 26 cell collection and dramatically decreased the cost of the procedure by decreasing the number of pheresis required. The multi-functional hematopoietic receptor agonist may be useful in mobilization of stem cells 5 and further enhance the efficacy of peripheral stem cell transplantation.

The multi-functional hematopoietic receptor agonists of the present invention may also be useful 10 in the ex vivo expansion of hematopoietic progenitors and stem cells. Colony stimulating factors (CSFs), such as hIL-3, have been administered alone, coadministered with other CSFs, or in combination with bone marrow transplants subsequent to high dose 15 chemotherapy to treat the neutropenia and thrombocytopenia which are often the result of such treatment. However the period of severe neutropenia and thrombocytopenia may not be totally eliminated. The myeloid lineage, which is comprised of monocytes 2 0 (macrophages), granulocytes (including neutrophils) and megakaryocytes, is critical in preventing infections and bleeding which can be life-threatening. Neutropenia and thrombocytopenia may also be the result of disease, genetic disorders, 25 drugs, toxins, radiation and many therapeutic treatments such as conventional oncology therapy.

Bone marrow transplants have been used to treat this patient population. However, several problems are associated with the use of bone marrow to 30 reconstitute a compromised hematopoietic system including: 1) the number of stem cells in bone marrow, spleen, or peripheral blood is limited, 2) Graft Versus Host Disease, 3) graft rejection and 4) possible contamination with tumor cells. Stem cells 35 make up a very small percentage of the nucleated cells in the bone marrow, spleen and peripheral blood. It is clear that a dose response exists such Printed from Mimosa 27 that a greater number of stem cells will enhance hematopoietic recovery. Therefore, the in vitro expansion of stem cells should enhance hematopoietic recovery and patient survival. Bone marrow from an 5 allogeneic donor has been used to provide bone marrow for transplant. However, Graft Versus Host Disease and graft rejection limit bone marrow transplantation even in recipients with HLA-matched sibling donors. An alternative to allogeneic bone marrow transplants 10 is autologous bone marrow transplants. In autologous bone marrow transplants, some of the patient's own marrow is harvested prior to myeloablative therapy, e.g. high dose chemotherapy, and is transplanted back into the patient afterwards. Autologous transplants 15 eliminate the risk of Graft Versus Host Disease and graft rejection. However, autologous bone marrow transplants still present problems in terms of the limited number of stems cells in the marrow and possible contamination with tumor cells. The limited 20 number of stem cells may be overcome by ex-vivo expansion of the stem'cells. In addition, stem cells can be specifically isolated, based on the presence of specific surface antigens such as CD34+ in order to decrease tumor cell contamination of the marrow 25 graft.

The long term culturing of highly enriched CD34+ precursors of hematopoietic progenitor cells from human bone marrow in cultures containing IL-la, IL-3, IL-6 or GM-CSF is discussed in Brandt et al J. Clin. 25 Invest. 86:932-941, 1990).

One aspect of the present invention provides a method for selective ex-vivo expansion of stem cells. The term "stem cell" refers to the totipotent 30 hematopoietic stem cells as well as early precursors and progenitor cells which can be isolated from bone marrow, spleen or peripheral blood. The term "expansion" refers to the differentiation and proliferation of the cells. The present invention 35 provides a method for selective ex-vivo expansion of stem cells, comprising the steps of: (a) separating stem cells from other cells, (b) culturing said Printed from Mimosa separated stem cells with a selective media which contains multi-functional hematopoietic receptor agonist protein(s) and (c) harvesting said stems cells. Stem cells, as well as committed progenitor 5 cells destined to become neutrophils, erythrocytes, platelets, etc. may be distinguished from most other cells by the presence or absence of particular progenitor marker antigens, such as CD34, that are present on the surface of these cells and/or by 10 morphological characteristics. The phenotype for a highly enriched human stem cell fraction is reported as CD34+, Thy-1+ and lin-, but it is to be understood that the present invention is not limited to the expansion of this stem cell population. The CD34+ 15 enriched human stem cell fraction can be separated by a number of reported methods, including affinity columns or beads, magnetic beads or flow cytometry using antibodies directed to surface antigens such as the CD34+. Further, physical separation methods such 20 as counterflow elutriation may be used to enrich hematopoietic progenitors. The CD34+ progenitors are heterogeneous, and may be divided into several sub-populations characterized by the presence or absence of co-expression of different lineage associated cell 25 surface associated molecules. The most immature progenitor cells do not express any known lineage associated markers, such as HLA-DR or CD38, but they may express CD90(thy-l). Other surface antigens such as CD33, CD3 8, CD41, CD71, HLA-DR or c-kit can also 3 0 be used to selectively isolate hematopoietic progenitors. The separated cells can be incubated in selected medium in a culture flask, sterile bag or in hollow fibers. Various colony stimulating factors may be utilized in order to selectively expand cells.. 35 Representative factors that have been utilized for ex-vivo expansion of bone marrow include, c-kit ligand, IL-3, G-CSF, GM-CSF, IL-1, IL-6, IL-11, flt3 Printed from Mimosa 31 ligand or combinations thereof. The proliferation of the stem cells can be monitored by enumerating the number of stem cells and other cells, by standard techniques (e.g. hemacytometer, CFU, LTCIC) or by 5 flow cytometry prior and subsequent to incubation.

Several methods for ex-vivo expansion of stem cells have been reported utilizing a number of selection methods and expansion using various colony 10 stimulating factors including c-kit ligand (Brandt et al., Blood 83:1507-1514 [1994], McKenna et al., Blood 86:3413-3420 [1995]), IL-3 (Brandt et al., Blood 83:1507-1514 [1994], Sato et al., Blood 82:3600-3609 [1993]), G-GSF (Sato et al., Blood 82:3600-3609 15 [1993]), GM-CSF (Sato et al., Blood 82:3600-3609 [1993]), IL-1 (Muench et al., Blood 81:3463-3473 [1993]), IL-6 (Sato et al., Blood 82:3600-3609 [1993]), IL-11 (Lemoli et al., Exp. Hem. 21:1668-1672 [1993], Sato et al., Blood 82:3600-3609 [1993]), flt3 20 ligand (McKenna et al., Blood 86:3413 3420 [1995]) and/or combinations thereof (Brandt et al. , Blood 83:1507 1514 [1994], Haylock et al., Blood 80:1405-1412 [1992], Koller et al., Biotechnology 11:358-363 [1993], (Lemoli et al., Exp. Hem. 21:1668-1672 25 [1993]), McKenna et al., Blood 86:3413-3420 [1995], Muench et al., Blood 81:3463-3473 [1993], Patchen et al., Biotherapy 7:13-26 [1994], Sato et al., Blood 82:3600-3609 [1993], Smith et al., Exp. Hem. 21:870-877 [1993], Steen et al., Stem Cells 12:214-224 30 [1994], Tsujino et al., Exp. Hem. 21:1379-1386

[1993]). Among the individual colony stimulating factors, hIL-3 has been shown to be one of the most potent in expanding peripheral blood CD34+ cells (Sato et al., Blood 82:3600-3609 [1993], Kobayashi et 35 al., Blood 73:1836-1841 [1989]). However, no single factor has been shown to be as effective as the combination of multiple factors. The present Printed from Mimosa WO 98/46750 PCT/US98/07511 32 invention provides methods for ex vivo expansion that utilise multi-functional hematopoietic receptor agonists that are more effective than a single factor alone.

Another aspect of the invention provides methods of sustaining and/or expanding hematopoietic precursor cells which includes inoculating the cells into a culture vessel which contains a culture medium 10 that has been conditioned by exposure to a stromal cell line such as HS-5 (WO 96/02662, Roecklein and Torok-Strob, Blood 85:997-1105, 1995) that has been supplemented with a multi-functional hematopoietic receptor agonist of the present invention.

Another projected clinical use of growth factors has been in the in vitro activation of hematopoietic progenitors and stem cells for gene therapy. Due to the long life-span of hematopoietic progenitor cells 20 and the distribution of their daughter cells throughout the entire body, hematopoietic progenitor cells are good candidates for ex vivo gene transfection. In order to have the gene of interest incorporated into the genome of the hematopoietic 25 progenitor or stem cell one needs to stimulate cell division and DNA replication. Hematopoietic stem cells cycle at a very low frequency which means that growth factors may be useful to promote gene transduction and thereby enhance the clinical 30 prospects for gene therapy. Potential applications of gene therapy (review Crystal, Science 270:404-410 [1995]) include; 1) the treatment of many congenital metabolic disorders and immunodeficiencies (Kay and Woo, Trends Genet. 10:253-257 [1994]), 2) 35 neurological disorders (Friedmann, Trends Genet. 10:210-214 [1994]), 3) cancer (Culver and Blaese, Trends Genet. 10:174-178 [1994]) and 4) infectious Printed from Mimosa 33 diseases (Gilboa and Smith, Trends Genet. 10:139-144 [1994]) .

There are a variety of methods, known to those with skill in the art, for introducing genetic 5 material into a host cell. A number of vectors, both viral and non-viral have been developed for transferring therapeutic genes into primary cells. Viral based vectors include; 1) replication deficient recombinant retrovirus (Boris-Lawrie and Temin, Curr. 10 Opin. Genet. Dev. 3:102-109 [1993], Boris-Lawrie and Temin, Annal. New York Acad. Sci. 716:59-71 [1994], Miller, Current Top. Microbiol. Immunol. 158:1-24 [1992]) and replication-deficient recombinant adenovirus (Berkner, BioTechniques 6:616-629 [1988], 15 Berkner, Current Top. Microbiol. Immunol. 158:39-66

[1992], Brody and Crystal, Annal. New York Acad. Sci. 716:90-103 [1994]). Non-viral based vectors include protein/DNA complexes (Cristiano et al., PNAS USA. 90:2122-2126 [1993], Curiel et al., PNAS USA 88:8850-20 8854 [1991], Curiel, Annal. New York Acad. Sci. 716:36-58 [1994]), electroporation and liposome mediated delivery such as cationic liposomes (Farhood et al., Annal. New York Acad. Sci. 716:23-35 [1994]).

The present invention provides an improvement to 25 the existing methods of expanding hematopoietic cells, which new genetic material has been introduced, in that it provides methods utilizing multi-functional hematopoietic receptor agonist proteins that have improved biological activity, 30 including an activity not seen by any single colony stimulation factor.

Many drugs may cause bone marrow suppression or hematopoietic deficiencies. Examples of such drugs are AZT, DDI, alkylating agents and anti-metabolites 35 used in chemotherapy, antibiotics such as chloramphenicol, penicillin, gancyclovir, daunomycin and sulfa drugs, phenothiazones, tranquilizers such Printed from Mimosa 34 as meprobamate, analgesics such as aminopyrine and dipyrone, anti-convulsants such as phenytoin or carbamazepine, antithyroids such as propylthiouracil and methimazole and diuretics. The multi-functional 5 hematopoietic receptor agonists of the present invention may be useful in preventing or treating the bone marrow suppression or hematopoietic deficiencies which often occur in patients treated with these drugs.

Hematopoietic deficiencies may also occur as a result of viral, microbial or parasitic infections and as a result of treatment for renal disease or renal failure, e.g., dialysis. The multi-functional hematopoietic receptor agonists of the present 15 invention may be useful in treating such hematopoietic deficiencies.

Various immunodeficiencies, e.g., in T and/or B lymphocytes, or immune disorders, e.g., rheumatoid arthritis, may also be beneficially affected by 20 treatment with the multi-functional hematopoietic receptor agonists of the present invention. Immunodeficiencies may be the result of viral infections, e.g., HTLVI, HTLVII, HTLVIII, severe exposure to radiation, cancer therapy or the result 25 of other medical treatment. The multi-functional hematopoietic receptor agonists of the present invention may also be employed, alone or in combination with other colony stimulating factors, in the treatment of other blood cell deficiencies, 30 including thrombocytopenia (platelet deficiency), or anemia. Other uses for these novel polypeptides are the in vivo and ex vivo treatment of patients recovering from bone marrow transplants, and in the development of monoclonal and polyclonal antibodies 3 5 generated by standard methods for diagnostic or therapeutic use.

Printed from Mimosa WO 98/46750 PCT/US98/07511 Other aspects of the present invention are methods and therapeutic compositions for treating the conditions referred to above. Such compositions comprise a therapeutically effective amount of one or 5 more of the multi-functional hematopoietic receptor agonists of the present invention in a mixture with a pharmaceutically acceptable carrier. This composition can be administered either parenterally, intravenously or subcutaneously. When administered, 10 the therapeutic composition for use in this invention is preferably in the form of a pyrogen-free, parenterally acceptable aqueous solution. The preparation of such a parenterally acceptable protein solution, having due regard to pH, isotonicity, 15 stability and the like, is within the skill of the art. The treatment of hematopoietic deficiency may include administration of a pharmaceutical composition containing the multi-functional hematopoietic receptor agonists to a patient. The 20 multi-functional hematopoietic receptor agonists of the present invention may also be useful for the activation and amplification of hematopoietic precursor cells by treating these cells in vitro with the multi-functional hematopoietic receptor agonist 25 proteins of the present invention prior to injecting the cells into a patient.

The dosage regimen involved in a method for treating the above-described conditions will be 30 determined by the attending physician considering various factors which modify the action of drugs, e.g., the condition, body weight, sex and diet of the patient, the severity of any infection, time of administration and other clinical factors. 35 Generally, a daily regimen may be in the range of 0.2 - 150 lag/kg of multi-functional hematopoietic receptor agonist protein per kilogram of body weight.

Printed from Mimosa 36 Dosages would be adjusted relative to the activity of a given multi-functional hematopoietic receptor agonist protein and it would not be unreasonable to note that dosage regimens may include doses as low as 5 0.1 microgram and as high as 1 milligram per kilogram of body weight per day. In addition, there may exist specific circumstances where dosages of multifunctional hematopoietic receptor agonist would be adjusted higher or lower than the range of 0.2 - 150 10 micrograms per kilogram of body weight. These include co-administration with other hematopoietic growth factors or IL-3 variants or growth factors; co-administration with chemotherapeutic drugs and/or radiation; the use of glycosylated multi-functional 15 hematopoietic receptor agonist protein; and various patient-related issues mentioned earlier in this section. As indicated above, the therapeutic method and compositions may also include co-administration or sequential administration other hematopoietic 20 growth factors. A non-exclusive list of other appropriate hematopoietic growth factors, colony stimulating factors (CSFs), cytokines, lymphokines, and interleukins for simultaneous or serial coadministration with the chimeric proteins of the 25 present invention includes GM-CSF, G-CSF, G-CSF Serl7, c-mpl ligand (also known as TPO or MGDF), M-CSF, erythropoietin (EPO), IL-1, IL-4, IL-2, IL-3, IL-3 variant, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, IL-15, IL-16, LIF, B-cell growth 30 factor, B-cell differentiation factor and eosinophil differentiation factor, stem cell factor (SCF) also known as steel factor or c-kit ligand, SCSF, SDF-1 or combinations thereof. "hIL-3 variant" is defined as a hIL-3 molecule which has amino acid substitutions 35 and/or portions of hIL-3 deleted as disclosed in WO 94/12638, WO 94/12639 and WO 95/00646, as well as other variants known in the art. The dosage recited Printed from Mimosa WO 98/46750 PCT/US98/07511 37 above would be adjusted to compensate for such additional components in the therapeutic composition. Progress of the treated patient can be monitored by-periodic assessment of the hematological profile, 5 e.g., differential cell count and the like.

Determination of activity of the chimeric proteins Biological activity of the multi-functional 10 hematopoietic receptor agonist proteins of the present invention can be determined by DNA synthesis in factor-dependent cell lines or by counting the colony forming units in an in vitro bone marrow assay. The chimeric proteins may be assayed by a 15 number of in vitro and in vivo models known to those skilled in the art. Examples of such assays include put are not limited to: Methylcellulose Assay This assay reflects the ability of colony stimulating factors to stimulate normal bone marrow cells to produce different types of hematopoietic colonies in vitro (Bradley et al., Aust. Exp Biol. Sci. 44:287-25 300, 1966), Pluznik et al., J. Cell Comp. Physio 66:319-324, 1965) .

Methods Approximately 3 0 mL of fresh, normal, healthy bone 30 marrow aspirate are obtained from individuals following informed consent. Under sterile conditions samples are diluted 1:5 with a IX PBS (#14040.059 Life Technologies, Gaithersburg, MD.) solution in a 50 mL conical tube (#25339-50 Corning, Corning MD). 35 Ficoll (Histopaque 1077 Sigma H-8889) is layered under the diluted sample and centrifuged, 3 00 x g for 3 0 min. The mononuclear cell band is removed and Printed from Mimosa 38 washed two times in IX PBS and once with 1% BSA PBS (CellPro Co., Bothel, WA). Mononuclear cells are counted and CD34+ cells are selected using the Ceprate LC (CD34) Kit (CellPro Co., Bothel, WA) 5 column. This fractionation is performed since all stem and progenitor cells within the bone marrow display CD34 surface antigen.

Cultures are set up in triplicate with a final volume 10 of 1.0 mL in a 35 X 10 mm petri dish (Nunc#174926). Culture medium is purchased from Terry Fox Labs. (HCC-4230 medium (Terry Fox Labs, Vancouver, B.C., Canada) and erythropoietin (Amgen, Thousand Oaks, CA.) is added to the culture media. 3,000-10,000 15 CD34+ cells are added per dish. Recombinant IL-3, purified from mammalian cells or E. coli, and multifunctional hematopoietic receptor agonist proteins, in conditioned media from transfected mammalian cells or purified from conditioned media from transfected 20 mammalian cells or E. coli, are added to give final concentrations ranging from .001 nM to 10 nM. Recombinant hIL-3, GM-CSF, c-mpl ligand and multifunctional hematopoietic receptor agonist are supplied in house. G-CSF (Neupogen) is from Amgen 25 (Thousand Oaks Calf.). Cultures are resuspended using a 3cc syringe and 1.0 mL is dispensed per dish. Control (baseline response) cultures received no colony stimulating factors. Positive control cultures received conditioned media (PHA stimulated 30 human cells: Terry Fox Lab. H2400). Cultures are incubated at 37°C, 5% C02 in humidified air. Hematopoietic colonies which are defined as greater than 50 cells are counted on the day of peak response (days 10-11) using a Nikon inverted phase microscope 35 with a 40x objective combination. Groups of cells containing fewer than 50 cells are referred to as clusters. Alternatively colonies can be identified by Printed from Mimosa 39 spreading the colonies on a slide and stained or they can be picked, resuspended and spun onto cytospin slides for staining.

Human Cord Blood Hemopoietic Growth Factor Assays Bone marrow cells are traditionally used for in vitro assays of hematopoietic colony stimulating factor (CSF) activity. However, human bone marrow is not 10 always available, and there is considerable variability between donors. Umbilical cord blood is comparable to bone marrow as a source of hematopoietic stem cells and progenitors (Broxmeyer et a:l. , PNAS USA 89:4109-113, 1992; Mayani et al. , 15 Blood 81:3252-3258, 1993). In contrast to bone marrow, cord blood is more readily available on a regular basis. There is also a potential to reduce assay variability by pooling cells obtained fresh from several donors, or to create a bank of 20 cryopreserved cells for this purpose. By modifying the culture conditions, and/or analyzing for lineage specific markers, it is be possible to assay specifically for granulocyte / macrophage colonies (CFU-GM), for megakaryocyte CSF activity, or for high 25 proliferative potential colony forming cell (HPP-CFC) activity.

Methods Mononuclear cells (MNC) are isolated from cord blood 30 within 24 hr. of collection, using a standard density gradient (1.077 g/mL Histopaque). Cord blood MNC have been further enriched for stem cells and progenitors by several procedures, including immunomagnetic selection for CD14-, CD34+ cells; panning for SBA-, 35 CD34+ fraction using coated flasks from Applied Immune Science (Santa Clara, CA); and CD34+ selection using a CellPro (Bothell, WA) avidin column. Either freshly isolated or cryopreserved Printed from Mimosa WO 98/46750 PCT/US98/07511 4° CD34+ cell enriched fractions are used for the assay. Duplicate cultures for each serial dilution of sample (concentration range from 1 pM to 1204 pM) are prepared with 1x104 cells in 1ml of 0.9% 5 methycellulose containing medium without additional growth factors (Methocult H423 0 from Stem Cell Technologies, Vancouver, BC.). In some experiments, Methocult H4330 containing erythropoietin (EPO) was used instead of Methocult H423 0, or Stem Cell Factor 10 (SCF), 50 ng/mL (Biosource International, Camarillo, CA) was added. After culturing for 7-9 days, colonies containing >30 cells are counted. In order to rule out subjective bias in scoring, assays are scored blind.

AML Proliferation Assay for Bioactive Human Interleukin-3 The factor-dependent cell line AML 193 was obtained from the American Type Culture Collection 20 (ATCC, Rockville, MD) . This cell line, established from a patient with acute myelogenous leukemia, is a growth factor dependent cell line which displayed enhanced growth in GM-CSF supplemented medium (Lange, B., et al., Blood 70: 192, 1987; Valtieri, 25 M., et al. , J. Immunol. 138:4042, 1987) . The ability of AML 193 cells to proliferate in the presence of human IL-3 has also been documented. (Santoli, D. , et al. , J. Immunol. 139: 348, 1987). A cell line variant was used, AML 193 1.3, which was adapted for 30 long term growth in IL-3 by washing out the growth factors and starving the cytokine dependent AML 193 cells for growth factors for 24 hours. The cells are then replated at lxlO5 cells/well in a 24 well plate in media containing 100 U/mL IL-3. It took 35 approximately 2 months for the cells to grow rapidly in IL-3. These cells are maintained as AML 193 1.3 Printed from Mimosa WO 98/46750 PCT/US98/07511 41 thereafter by supplementing tissue culture medium (see below) with human IL-3.

AML 193 1.3 cells are washed 6 times in cold Hanks balanced salt solution (HBSS, Gibco, Grand 5 Island, NY) by centrifuging cell suspensions at 250 x g for 10 minutes followed by decantation of the supernatant. Pelleted cells are resuspended in HBSS and the procedure is repeated until six wash cycles are completed. Cells washed six times by this 10 procedure are resuspended in tissue culture medium at a density ranging from 2 x 105 to 5 x 105 viable cells/mL. This medium is prepared by supplementing Iscove's modified Dulbecco's Medium (IMDM, Hazelton, Lenexa, KS) with albumin, transferrin, lipids and 2-15 mercaptoethanol. Bovine albumin (Boehringer- Mannheim, Indianapolis, IN) is added at 500 yg/mL; human transferrin (Boehringer-Mannheim, Indianapolis, IN) is added at 100 jig/mL; soybean lipid (Boehringer-Mannheim, Indianapolis, IN) is added at 50 ug/mL; and 20 2-mercaptoethanol (Sigma, St. Louis, MO) is added at 5 x 10"5 M.

Serial dilutions of human interleukin-3 or multi-functional chimeric hematopoietic receptor agonist proteins are made in triplicate series in 25 tissue culture medium supplemented as stated above in 96 well Costar 3596 tissue culture plates. Each well contained 50 ]il of medium containing interleukin-3 or multi-functional chimeric hematopoietic receptor agonist proteins once serial dilutions are completed. 3 0 Control wells contained tissue culture medium alone (negative control). AML 193 1.3 cell suspensions prepared as above are added to each well by pipetting 4 50 ul (2.5 x 10 cells) into each well. Tissue culture plates are incubated at 37°C with 5% CO2 in Printed from Mimosa 42 humidified air for 3 days. On day 3, 0.5 yiCi 3H-thymidine (2 Ci/mM, New England Nuclear, Boston, MA) is added in 50 pi of tissue culture medium. Cultures are incubated at 37°C with 5% CO2 in humidified air 5 for 18-24 hours. Cellular DNA is harvested onto glass filter mats (Pharmacia LKB, Gaithersburg, MD) using a TOMTEC cell harvester (TOMTEC, Orange, CT) which utilized a water wash cycle followed by a 70% ethanol wash cycle. Filter mats are allowed to air 10 dry and then placed into sample bags to which scintillation fluid (Scintiverse II, Fisher Scientific, St. Louis, MO or BetaPlate Scintillation Fluid, Pharmacia LKB, Gaithersburg, MD) is added.

Beta emissions of samples from individual tissue 15 culture wells are counted in a LKB BetaPlate model 1205 scintillation counter (Pharmacia LKB, Gaithersburg, MD) and data is expressed as counts per minute of 3H-thymidine incorporated into cells from each tissue culture well. Activity of each human 20 interleukin-3 preparation or multi-functional chimeric hematopoietic receptor agonist protein preparation is quantitated by measuring cell proliferation' (3H-thymidine incorporation) induced by graded concentrations of interleukin-3 or multi-25 functional chimeric hematopoietic receptor agonist.

Typically, concentration ranges from 0.05 pM - 105 pM are quantitated in these assays. Activity is determined by measuring the dose of interleukin-3 or multi-functional chimeric hematopoietic receptor 3 0 agonist protein which provides 50% of maximal proliferation (EC50 = 0.5 x (maximum average counts per minute of 3H-thymidine incorporated per well among triplicate cultures of all concentrations of interleukin-3 tested - background proliferation Printed from Mimosa 43 measured by 3H-thymidine incorporation observed in triplicate cultures lacking interleukin-3). This EC50 value is also equivalent to 1 unit of bioactivity. Every assay is performed with native interleukin-3 as 5 a reference standard so that relative activity levels could be assigned.

Typically, the multi-functional chimeric hematopoietic receptor agonist proteins were tested in a concentration range of 2000 pM to 0.06 pM 10 titrated in serial 2 fold dilutions.

Activity for each sample was determined by the concentration which gave 50% of the maximal response by fitting a four-parameter logistic model to the data. It was observed that the upper plateau 15 (maximal response) for the sample and the standard with which it was compared did not differ. Therefore relative potency calculation for each sample was determined from EC50 estimations for the sample and the standard as indicated above. AML 193.1.3 cells 20 proliferate in response to hIL-3, hGM-CSF and hG-CSF. TF1 c-mpl ligand dependent proliferation assay The c-mpl ligand proliferative activity can be assayed using a subclone of the pluripotential human 25 cell line TF1 (Kitamura et al., J. Cell Physiol 140:323-334. [1989]). TF1 cells are maintained in h-IL3 (100 U/mL). To establish a sub-clone responsive to c-mpl ligand, cells are maintained in passage media containing 10% supernatant from BHK cells 30 transfected with the gene expressing the 1-153 form of c-mpl ligand (pMON26448). Most of the cells die, but a subset of cells survive. After dilution cloning, a c-mpl ligand responsive clone is selected, and these cells are split into passage media to a 35 density of 0.3 x 106 cells/mL the day prior to assay Printed from Mimosa 44 set-up. Passage media for these cells is the following: RPMI 1640 (Gibco), 10% FBS (Harlan, Lot #91206), 10% c-mpl ligand supernatant from transfected BHK cells, 1 mM sodium pyruvate (Gibco), 5 2 mM glutamine (Gibco), and 100 ug/mL penicillin-streptomycin (Gibco). The next day, cells are harvested and washed twice in RPMI or IMDM media with a final wash in the ATL, or assay media. ATL medium consists of the following: IMDM (Gibco), 500 ug/mL of 10 bovine serum albumin, 100 ug/mL of human transferrin, 50 ug/mL soybean lipids, 4 x 10-8M beta-mercaptoethanol and 2 mL of A9909 (Sigma, antibiotic solution) per 1000 mL of ATL. Cells are diluted in assay media to a final density of 0.25 x 106 cells/mL 15 in a 96-well low evaporation plate (Costar) to a final volume of 50 ul. Transient supernatants (conditioned media) from transfected clones are added at a volume of 5 0 ul as duplicate samples at a final concentration of 50% and diluted three-fold to a 20 final dilution of 1.8%. Triplicate samples of a dose curve of IL-3 variant pMONl3288 starting at 1 ng/mL and diluted using three-fold dilutions to 0.0014ng/mL is included as a positive control. Plates are incubated at 5% CO2 and 37° C. At day six of 25 culture, the plate is pulsed with 0.5 Ci of 3H/well (NEN) in a volume of 20 ul/well and allowed to incubate at 5% CO2 and 37° C for four hours. The plate is harvested and counted on a Betaplate counter.

MUTZ-2 Cell Proliferation Assay Printed from Mimosa 45 A cell line such as MUTZ-2, which is a human myeloid leukemia cell line (German Collection of Microorganisms and Cell Cultures, DSM ACC 271), can be used to determine the cell proliferative activity 5 of flt3 receptor agonists. MUTZ-2 cultures are maintained with recombinant native flt3 ligand (20— lOOng/mL) in the growth medium. Eighteen hours prior to assay set-up, MUTZ-2 cells are washed in IMDM medium (Gibco) three times and are resuspended in 10 IMDM medium alone at a concentration of 0.5-0.7 x 10E6 cells/mL and incubated at 37°C and 5%CC>2 to starve the cells of flt3 ligand. The day of the assay, standards and flt3 receptor agonists are diluted to two fold above desired final concentration 15 in assay media in sterile tissue culture treated 96 well plates. Flt3 receptor agonists and standards are tested in triplicate. 50ul of assay media is loaded into all wells except row A. 75^1 of the flt3 receptor agonists or standards are added to row A and 20 25|il taken from that row and serial dilutions (1:3) performed on the rest of the plate (rows B through G). Row H remains as a media only control. The starved MUTZ-2 cells are washed two times in IMDM medium and resuspended in 50ul assay media. 50pl of 25 'cells are added to each well resulting in a final concentration of 0.25 x 10E6cells/mL. Assay plates containing cells are incubated at 37°C and 5%CC>2 for 44hrs. Each well is then pulsed with luCi/well of tritiated thymidine in a volume of 20ul for four 30 hours. Plates are then harvested and counted.

Other in vitro cell based proliferation assays Printed from Mimosa 46 Other in vitro cell based assays, known to those skilled in the art, may also be useful to determine the activity of the multi-functional chimeric hematopoietic receptor agonists depending on the 5 factors that comprise the molecule in a similar manner as described in the AML 193.1.3 cell proliferation assay. The following are examples of other useful assays.

TF1 proliferation assay: TF1 is a pluripotential human cell line (Kitamura et al., J. Cell Physiol 140:323-334. [1989]) that responds to hIL-3. 32D proliferation assay: 32D is a murine IL-3 15 dependent cell line which does not respond to human IL-3 but does respond to human G-CSF which is not species restricted.

Baf/3 proliferation assay: Baf/3 is a murine IL-3 20 dependent cell line which does not respond to human IL-3, human flt3 ligand or human c-mpl ligand but does respond to human G-CSF which is not species restricted.

T1165 proliferation assay: T1165 cells are a IL-6 dependent murine cell line (Nordan et al., 1986) which respond to IL-6 and IL-11.

Human Plasma Clot meg-CSF Assay: Used to assay 3 0 megakaryocyte colony formation activity (Mazur et al., 1981) .

Transfected cell lines: Cell lines such as the murine Baf/3 cell line 35 can be transfected with a hematopoietic growth factor Printed from Mimosa 47 receptor, such as the human G-CSF receptor or human c-mpl receptor, which the cell line does not have. These transfected cell lines can be used to determine the activity of the ligand for which the receptor has 5 been transfected into the cell line.

One such transfected Baf/3 cell line was made by cloning the cDNA encoding c-mpl from a library made from a c-mpl responsive cell line and cloned into the multiple cloning site of the plasmid 10 pcDNA3 (Invitrogen, San Diego Ca.). Baf/3 cells were transfected with the plasmid via electroporation. The cells were grown under G418 selection in the presence of mouse IL-3 in Wehi conditioned media. Clones were established through limited dilution. 15 In a similar manner the human G-CSF receptor can be transfected into the Baf/3 cell line and used to determine the bioactivity of the multi-functional chimeric hematopoietic receptor agonists.

Analysis of c-mpl ligand proliferative activity Methods 1. Bone marrow proliferation assay 25 a. CD34+ Cell Purification: Bone marrow aspirates (15-20 mL) were obtained from normal allogeneic marrow donors after informed consent. Cells were diluted 1:3 in phosphate 30 buffered saline (PBS, Gibco-BRL), 30 mL were layered over 15 mL Histopaque-1077 (Sigma) and centrifuged for 3 0 minutes at 3 00 RCF. The mononuclear interface layer was collected and washed in PBS. CD34+ cells were enriched from the mononuclear cell preparation 35 using an affinity column per manufacturers Printed from Mimosa 48 PCT /US98/07511 instructions (CellPro, Inc., Bothell WA). After enrichment, the purity of CD34+ cells was 70% on average as determined by using flow cytometric analysis using anti-CD34 monoclonal antibody 5 conjugated to fluorescein and anti-CD3 8 conjugated to phycoerythrin (Becton Dickinson, San Jose CA).

Cells were resuspended at 40,000 cells/mL in X-Vivo 10 media (Bio-Whittaker, Walkersville, MD) and 1 mL was plated in 12-well tissue culture plates 10 (Costar). The growth factor rhIL-3 was added at 100 ng/mL (pMON5873) was added to some wells. hIL3 variants were used at 10 ng/mL to 100 ng/mL. Conditioned media from BHK cells transfected with plasmid encoding c-mpl ligand or multi-functional 15 chimeric hematopoietic receptor agonists were tested by addition of 100 pi of supernatant added to 1 mL cultures (approximately a 10% dilution). Cells were incubated at 37°C for 8-14 days at 5% CO2 in a 37°C humidified incubator. b. Cell Harvest and Analysis: At the end of the culture period a total cell count was obtained for each condition. For fluorescence analysis and ploidy determination cells 25 were washed in megakaryocyte buffer (MK buffer, 13.6 mM sodium citrate, 1 mM theophylline, 2.2 pm PGEl, 11 mM glucose, 3% w/v BSA, in PBS, pH 7.4,) (Tomer et al., Blood 70: 1735-1742, 1987) resuspended in 500 pi of MK buffer containing anti-CD41a FITC antibody 30 (1:200, AMAC, Westbrook, ME) and washed in MK buffer. For DNA analysis cells were permeablized in MK buffer containing 0.5% Tween 20 (Fisher, Fair Lawn NJ)for 20 min. on ice followed by fixation in 0.5% Tween-20 and 1% paraformaldehyde (Fisher Chemical) for 3 0 minutes 35 followed by incubation in propidium iodide Printed from Mimosa 49 (Calbiochem , La Jolla Ca) (50 jig/mL) with RNAase (400 U/mL) in 55% v/v MK buffer (200m0sm) for 1-2 hours on ice. Cells were analyzed on a FACScan or Vantage flow cytometer (Becton Dickinson, San Jose, 5 CA). Green fluorescence (CD41a-FITC) was collected along with linear and log signals for red fluorescence (PI) to determine DNA ploidy. All cells were collected to determine the percent of cells that were CD41+. Data analysis was performed using 10 software by LYSIS (Becton Dickinson, San Jose, CA). Percent of cells expressing the CD41 antigen was obtained from flow cytometry analysis(Percent). Absolute (Abs) number of CD41+ cells/mL was calculated by: (Abs)=(Cell Count)*(Percent)/100. 2. Megakaryocyte fibrin clot assay.

CD34+ enriched population were isolated as described above. Cells were suspended at 25,000 cells/mL with 20 or without cytokine(s) in a media consisting of a base Iscoves IMDM media supplemented with 0.3% BSA, 0.4mg/mL apo-transferrin, 6.67pM FeCl2, 25ug/mL CaCl2, 25ug/mL L-asparagine, 500]ig/mL e-amino-n-caproic acid and penicillin/streptomycin. Prior to 25 plating into 35mm plates, thrombin was added (0.25 Units/mL) to initiate clot formation. Cells were incubated at 37°C for 13 days at 5% CO2 in a 37°C humidified incubator.

At the end of the culture period plates were fixed with methanol:acetone (1:3), air dried and stored at -200C until staining. A peroxidase immunocytochemistry staining procedure was used (Zymed, Histostain-SP. San Francisco, CA) using a Printed from Mimosa WO 98/46750 PCT/US98/07511 50 cocktail of primary monoclonal antibodies consisting of anti-CD41a, CD42 and CD61. Colonies were counted after staining and classified as negative, CFU-MK (small colonies, 1-2 foci and less that approx. 25 5 cells), BFU-MK (large, multi-foci colonies with > 25 cells) or mixed colonies (mixture of both positive and negative cells.

Plasmids, pMON32392 and pMON32393, were 5 constructed by Polymerase Chain Reaction (PCR) methods. Plasmid, pMON30237 and pMON30238, DNA was used as the template in the PCR reaction with primer pairs N-term SEQ ID NO:29/134rev SEQ ID NO:30 and N-term SEQ ID NO:29/139rev SEQ ID NO:31, 10 respectively, to introduce an in-frame SnaBI restriction site at the C-terminus. Standard PCR reaction mixtures were set up using an Invitrogen PCR Optimizer kit (Invitrogen). Amplification cycle conditions were as follows: seven cycles of 15 94°C, one minute, 65°C, two minutes, and 72°C 2 1/2 minutes; followed by ten cycles of 94°C, one minute, 70°C, two minutes, and 72°C 2 1/2 minutes.
