Cell populations which co-express CD49c and CD90
First Claim
1. An isolated cell population induced to express at least one cardiac-related transcription factor, wherein the cell population is derived from bone marrow, wherein greater than about 91% of the cells of the cell population co-express CD49c and CD90, and wherein the cell population is capable of maintaining a doubling rate of less than about 30 hours after 30 cell doublings.

Abstract
Substantially homogenous cells populations which co-express CD49c, CD90 and telomerase are made. In one embodiment, humans suffering from a degenerative, traumatic, acute injury, cardiac or neurological condition are treated with the substantially homogenous cells populations which co-express CD49c, CD90 and telomerase. In another embodiment, committed progenitor cells are made are made by selecting from a cultured source of a cell population which co-express CD49c and CD90 and modifying the cell population. The committed progenitor cells can be employed to treat a human suffering from a degenerative, traumatic, acute injury, cardiac or neurological condition and to formulate pharmaceutical compositions. In a further embodiment, a substantially homogenous population of cells which co-express CD49c, CD90 and at least one cardiac-related transcription factor is made and can be used to treat a human suffering from a cardiac condition.
