Expansion and differentiation of EPCs from proliferated CD34⁺ cells. The ex-vivo expanded human CD34⁺ cells were cultured with the optimized medium recipe to induce EC differentiation (scale bar = 50 μm). a Cell morphology imaged with an optical microscope on days 0, 6, 9, 15, and 21. b Absolute number of VEGFR2⁺ cells at different time points. c Fold-increase in proliferation of VEGFR2⁺ cells at different time points. Data are mean ± SD; n = 10
