As these cells share characteristics of other progenitor cell phenotypes, late-outgrowth EPCs were assayed for both multilineage differentiation capability and for markers of pluripotency. Methods: Clonal single-colony late-outgrowth EPCs were derived from human cord blood and assayed both for multilineage differentiation capability in vitro and for markers of pluripotency by qPCR. Results: Under osteogenic growth conditions, these EPCs expressed the osteogenic markers RUNX2, COL1A1, ALPL, and osteocalcin and demonstrated calcium deposition and bone mineralization. Endothelial colony-forming cells expressed markers associated with induced pluripotent stem cells, including SOX2, POU5F1, c-MYC, and KLF4. Conclusions: Late-outgrowth EPCs express markers associated with pluripotency and can directly express an osteogenic phenotype under bone differentiation conditions in vitro. ER -
