Multipotent mesenchymal stem cells (MSCs) derived from human umbilical cord blood (hUCB) represent promising candidates for the development of future cellular therapy strategies. MSCs have been found to be able to differentiate into various tissues. One of the primary limitations in our understanding of the biology of human MSCs is the absence of prospective markers required for the monitoring of lineage-specific differentiation. hUCB-derived MSCs have been found to have significantly greater osteogenic potential. In this study, we focused on proteins that were differentially expressed during osteogenic differentiation of hUCB-MSCs. And we analyzed the protein expression inherent to osteogenic differentiation by two-dimensional gel electrophoresis, ESI-Q-TOF, and Western blotting. Eleven differentially expressed spots were observed between the two groups (before and after differentiation) on the 2-DE map. These might also be proved as useful cytosolic biomarker proteins for osteogenesis, and might be employed in quality control of osteoblasts in cell-therapy applications.
