FACS profile of selected surface antigens by iPSC-cells derived using different factors. The level of expression for each of the surface antigens that was assessed is indicated in the figure. bFG- derived cells comprise a population expressing high levels of CD34 and CD44. TGF-β1 and 3-derived cells were enriched in populations expressing CD13, CD73 and less CD105. IPSC-cells-derived by exposure to BMP-2 were enriched in a population of cells expressing high levels of CD73 and CD44 but less CD105. P < 0.05.
