Abstract: | Endothelial progenitor cells (EPCs) promote angiogenesis and play an important role in myocardial and vascular repair after ischemia and infarction. EPCs consist of different subpopulations including CD34- CD133+ EPCs, which are precursors of more mature CD34+CD133+ EPCs and functionally more active in terms of homing and endothelial regeneration. In the present study we analyzed the functional and differentiation abilities of CD34- CD133+ EPCs. Isolation of EPC populations (CD34+CD133+ , CD34- CD133+ ) were performed by specific multi-step magnetic depletion. After specific stimulation a significant higher adhesive and migrative capacity of CD34- CD133+ cells could be detected compared to CD34+CD133+ cells (P<0.001, respectively). Next to this finding, not only significantly higher rates of proliferation (P<0.005) were detected among CD34- CD133+ cells, but also a higher potential of cell-differentiation capacity into other cell types. Next to a significant increase of CD34- CD133+ EPCs differentiating into a fibroblast cell‑type (P<0.001), an enhancement into a hepatocytic cell-type (P=0.033) and a neural cell-type (P=0.016) could be measured in contrast to CD34+CD133+ cells. On the other hand, there was no significant difference in differentiation into a cardiomyocyte cell-type between these EPC subpopulations (P=0.053). These results demonstrate that EPC subpopulations vary in their functional abilities and, to different degrees, have the capacity to transdifferentiate into unrelated cell-types such as fibroblasts, hepatocytes, and neurocytes. This indicates that CD34- CD133+ cells are more pluripotent compared to the CD34+CD133+ EPC subset, which may have important consequences for the therapy of vascular diseases. |
