Abstract

Isolated or purified mammalian kidney-derived cell populations from mammalian kidney tissue are provided. Methods are provided for the isolation and purification of the mammalian kidney-derived cell population. Methods for treating kidney disease are provided by administration of the isolated or purified mammalian kidney-derived cell population to a mammalian subject.

First claim

What is claimed:

1. A method for treating ischemic kidney disease in a human or an immunocompromised mouse comprising administering directly to the kidney a therapeutically effective amount of an isolated or purified human kidney-derived cell population,
wherein said cell population is capable of self-renewal and expansion in culture, wherein the cell population is positive for expression of HLA-I and CD44 and at least one of Oct-4, Rex-1, Pax-2, Cadherin-11, FoxD1, WT1, Eya1, HNF3B, CXC-R4, Sox-17, EpoR, BMP2, BMP7, and GDF5, and negative for the expression of CD133, E-cadherin, and Wnt-4 and at least one of Sox2, FGF4, hTert, SIX2 and GATA-4, and
wherein said administration reduces or eliminates the ischemic kidney disease in the treated human or immunocompromised mouse.

2. The method of claim 1 , wherein the administration of said cell population induces an effect selected from: (a) formation of blood vessels supplying blood to the ischemic tissue; (b) blood flow to the ischemic tissue; (c) oxygen supply to the ischemic tissue; and (d) combinations thereof.

3. The method of claim 1 , wherein the administration of said cell population induces formation of kidney subcapsular region tissue, kidney cortex tissue, or kidney medulla tissue.

4. The method of claim 1 , wherein the treating ischemic kidney disease is in a human.

5. The method of claim 1 , wherein the human kidney-derived cell population is positive for expression of at least one of Eya1, WT1, FoxD1, BMP7, BMP2, GDF5, EpoR and Rex-1, and negative for expression of at least one of Sox2, FGF4, and hTert.

6. The method of claim 1 , wherein the human kidney-derived cell population is positive for at least one of cell-surface markers, CD24, CD29, CD49c, CD73, CD90, CD166, and SSEA-4, and negative for at least one of cell-surface markers HLA II, CD31, CD34, CD45, CD56, CD80, CD86, CD104, CD105, CD117, CD138, and CD141.

7. The method of claim 1 , wherein the human kidney-derived cell population is positive for at least one of the surface markers CD166 and SSEA-4, and negative for at least one of the cell-surface markers HLA II, CD80, CD86, CD133, CD141 and E-cadherin.

8. The method of claim 1 , wherein the human kidney-derived cell population is positive for the cell-surface marker HLA I, and negative for at least one of cell-surface markers HLA II, CD80, and CD86.

9. The method of claim 1 , wherein the human kidney-derived cell population is non-immunogenic for allogeneic transplantation in a human subject.

10. The method of claim 1 , wherein the human kidney-derived cell population is derived from kidney cortex, kidney medulla or kidney subcapsular region.

11. The method of claim 1 , wherein the method comprises administering a pharmaceutical composition comprising the isolated or purified human kidney-derived cell population.
