Human mesenchymal stem cells (hMSCs) have been paid a great deal of attention because of their unprecedented therapeutic merits endowed by powerful ex vivo expansion and multilineage differentiation potential. Umbilical cord blood (UCB) is a convenient but not fully proven source for hMSCs, and hence, greater experience is required to establish UCB as a reliable source of hMSCs. To this end, we attempted to isolate hMSC-like adherent cells from human UCB. The isolated cells were highly proliferative and exhibited an immunophenotype of CD13+ CD14− CD29+ CD31− CD34− CD44+ CD45− CD49e+ CD54+ CD90+ CD106− ASMA+ SH2+ SH3+ HLA-ABC+ HLA-DR−. More importantly, these cells, under appropriate conditions, could differentiate into a variety of mesenchymal lineage cells such as osteoblasts, chondrocytes, adipocytes, and skeletal myoblasts. This mesengenic potential assures that the UCB-derived cells are multipotent hMSCs and further implicates that UCB can be a legitimate source of hMSCs.
