Abstract

The invention provides improved methods for cell therapy. In particular, the invention provides therapeutic compositions of enhanced hematopoietic stem and progenitor cells having improved engraftment and homing properties, and methods of making the therapeutic compositions. The invention further provides methods of improving the efficacy of hematopoietic stem and progenitor cell transplantation including transplanting the therapeutic composition to subjects in need of hematopoietic system reconstitution.

First claim

The invention claimed is:

1. A method of treating a subject in need of hematopoietic stem cell therapy comprising administering to the subject a composition comprising:
a human hematopoietic stem or progenitor cell having CXCR4 gene expression of at least 30-fold greater compared to CXCR4 gene expression of a hematopoietic stem or progenitor cell that has not been contacted ex vivo with one or more agents that increase CXCR4 gene expression.

2. The method of claim 1 , wherein the subject has acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CIVIL), chronic lymphocytic leukemia (CLL), juvenile myelomonocytic leukemia, Hodgkin's lymphoma, non-Hodgkin's lymphoma, multiple myeloma, severe aplastic anemia, Fanconi's anemia, paroxysmal nocturnal hemoglobinuria (PNH), pure red cell aplasia, amegakaryocytosis/congenital thrombocytopenia, severe combined immunodeficiency syndrome (SCID), Wiskott-Aldrich syndrome, beta-thalassemia major, sickle cell disease, Hurler's syndrome, adrenoleukodystrophy, metachromatic leukodystrophy, myelodysplasia, refractory anemia, chronic myelomonocytic leukemia, agnogenic myeloid metaplasia, familial erythrophagocytic lymphohistiocytosis, solid tumors, chronic granulomatous disease, mucopolysaccharidoses, or Diamond Blackfan.

3. The method of claim 1 , wherein the subject has breast cancer, ovarian cancer, brain cancer, prostate cancer, lung cancer, colon cancer, skin cancer, liver cancer, pancreatic cancer, or sarcoma.

4. The method of claim 3 , wherein the subject has received bone marrow ablative or nonmyeloablative chemotherapy or radiation therapy.

5. The method of claim 1 , wherein the subject is a bone marrow donor.

6. The method of claim 1 , wherein the hematopoietic stem or progenitor cell is obtained from bone marrow, umbilical cord blood, mobilized peripheral blood, Wharton's jelly, placenta, fetal blood, or induced pluripotent stem cells (iPSCs).

7. A method of treating a subject in need of cell therapy comprising administering to the subject a composition comprising:
a human hematopoietic stem or progenitor cell that has been contacted ex vivo with one or more agents that increase CXCR4 gene expression in the cell by at least about 30 fold in the contacted hematopoietic stem or progenitor cell compared to a hematopoietic stem or progenitor cell that has not been contacted ex vivo with one or more agents that increase CXCR4 gene expression.

8. The method of claim 7 , wherein the one or more agents comprises (i) one or more prostaglandin pathway agonists; and (ii) one or more glucocorticoids.

9. The method of claim 8 , wherein the prostaglandin pathway agonist comprises a compound that selectively binds the PGE 2 EP 2 or PGE 2 EP 4 receptor.

10. The method of claim 9 , wherein the prostaglandin pathway agonist is selected from the group consisting of PGE 2 , dmPGE 2 , 15(S)-15-methyl PGE 2 , 20-ethyl PGE 2 , and 8-iso-16-cyclohexyl-tetranor PGE 2 .

11. The method of claim 9 , wherein the prostaglandin pathway agonist comprises 16, 16 dimethyl-PGE2.

12. The method of claim 8 , wherein the glucocorticoid is selected from the group consisting of medrysone, alclometasone, alclometasone dipropionate, amcinonide, beclometasone, beclomethasone dipropionate, betamethasone, betamethasone benzoate, betamethasone valerate, budesonide, ciclesonide, clobetasol, clobetasol butyrate, clobetasol propionate, clobetasone, clocortolone, cloprednol, cortisol, cortisone, cortivazol, deflazacort, desonide, desoximetasone, desoxycortone, dexamethasone, diflorasone, diflorasone diacetate, diflucortolone, diflucortolone valerate, difluorocortolone, difluprednate, fluclorolone, fluclorolone acetonide, fludroxycortide, flumethasone, flumethasone pivalate, flunisolide, flunisolide hemihydrate, fluocinolone, fluocinolone acetonide, fluocinonide, fluocortin, fluocoritin butyl, fluocortolone, fluorocortisone, fluorometholone, fluperolone, fluprednidene, fluprednidene acetate, fluprednisolone, fluticasone, fluticasone propionate, formocortal, halcinonide, halometasone, hydrocortisone, hydrocortisone acetate, hydrocortisone aceponate, hydrocortisone buteprate, hydrocortisone butyrate, loteprednol, meprednisone, 6a-methylprednisolone, methylprednisolone, methylprednisolone acetate, methylprednisolone aceponate, mometasone, mometasone furoate, mometasone furoate monohydrate, paramethasone, prednicarbate, prednisolone, prednisone, prednylidene, rimexolone, tixocortol, triamcinolone, triamcinolone acetonide and ulobetasol.

13. The method of claim 8 , wherein the prostaglandin pathway agonist is 16,16-dimethyl PGE 2 and the glucocorticoid is dexamethasone.

14. The method of claim 7 , wherein the subject has acute myelogenous leukemia (AML), acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CIVIL), chronic lymphocytic leukemia (CLL), juvenile myelomonocytic leukemia, Hodgkin's lymphoma, non-Hodgkin's lymphoma, multiple myeloma, severe aplastic anemia, Fanconi's anemia, paroxysmal nocturnal hemoglobinuria (PNH), pure red cell aplasia, amegakaryocytosis/congenital thrombocytopenia, severe combined immunodeficiency syndrome (SCID), Wiskott-Aldrich syndrome, beta-thalassemia major, sickle cell disease, Hurler's syndrome, adrenoleukodystrophy, metachromatic leukodystrophy, myelodysplasia, refractory anemia, chronic myelomonocytic leukemia, agnogenic myeloid metaplasia, familial erythrophagocytic lymphohistiocytosis, solid tumors, chronic granulomatous disease, mucopolysaccharidoses, or Diamond Blackfan.

15. The method of claim 7 , wherein the subject has breast cancer, ovarian cancer, brain cancer, prostate cancer, lung cancer, colon cancer, skin cancer, liver cancer, pancreatic cancer, or sarcoma.
