Characterization of mesenchymal stem cells (MSCs).

A) Illustrates a representative field of bone marrow-derived MSCs in different passages. Upper image: At the first, the isolated cells by bone marrow aspiration illustrate a round morphology. Lower image: The subculture 3 of the cells illustrates typical fibroblast-like morphology of MSCs. B) Immunophenotype of MSCs. The data indicated that the subculture 3 of the adherent isolated cells from the bone marrow of rats showed the MSC marker of rats (CD29 and CD90); nonetheless, they were negative for the marker of the hematopoietic cell (CD 45). Data are shown as the mean ±SD
