Emerging evidence has suggested a contribution of bone marrow (BM) cells to lymphatic vessel formation; however, the exact phenotype of the cells with lymphatic endothelial progenitor cell function has yet to be identified. Here, we investigate the identity of BM-derived lymphatic endothelial progenitor cells and their role in lymphatic neovascularization. Culture of BM-mononuclear cells in the presence of vascular endothelial growth factors A and C and endothelial growth factor resulted in expression of lymphatic endothelial cell markers. Among these cells, podoplanin(+) cells were isolated by magnetic-activated cell sorting

This study aimed to determine if CD31 is a novel marker of a circulating angio-vasculogenic cell population and to establish the cells’ therapeutic effects on experimental ischemia. Emerging evidence suggested that therapeutic mechanisms underlying various bone marrow-derived cells are due to paracrine effects. Furthermore, the vasculogenic potential of these cells is under debate. CD31 is a well-known marker for endothelial cells but is also expressed in a fraction of peripheral blood (PB) mononuclear cells. CD31(+) cells were isolated from human PB by magnetic-activated cell sorting. The gene expression

Bone marrow (BM) cells play an important role in physiological and therapeutic neovascularization. However, it remains unclear whether any specific uncultured BM cell populations have higher angiogenic and vasculogenic activities. Moreover, there has been controversy regarding the vasculogenic ability of BM cells. Preliminary flow cytometric analysis showed that CD31, traditionally a marker for endothelial cells, is expressed in certain nonendothelial BM mononuclear cells in both human and mouse. Based on the conserved CD31 expression in the axis of hematopoietic stem/progenitor cells (HSC/HPCs) to endothelial
