CD133 and CD34 expression of HPC cultured in IL-6 stimulated endothelial supernatant. after one week in culture (A) CD133 and CD34 were still present, whereas a distinct subset of CD133(+) cells did not stain for CD34. Reduced CD34 was paralleled by reduced CD133 positivity in the second week (B), while still more CD133(+)CD34(-) cells than double positive cells were detected.
