In the present study, we compared CFEs and bipotentiality to form osteoblasts and adipocytes by CB-MSC and BM-MSCs at PD50, a time when both cell populations showed similar gene expression profiles for MSC markers, CD73, CD90, and CD105, Nanog, the osteogenic marker Runx2, and cell cycle proteins, [p21.sup.waf1/CIP1], p53 (CD34, Oct4, and [p16.sup.INK4A] positivity was not detected).
