Kidney-derived cells and methods of use in tissue repair and regeneration
First Claim
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, andwherein said administration reduces or eliminates the ischemic kidney disease in the treated human or immunocompromised mouse.
