The expansion and differentiation of EPCs derived from CD34⁺ cells of nonhuman primate PB in vitro. The isolated nonhuman primate PB CD34⁺ cells were expanded and differentiated into endothelial progenitor cells (EPCs)/endothelial cells (ECs). a The morphology of induced EPCs was photographed by microscope every 3 days from day 0 to day 36 (scale bar = 50 μm). b Absolute cell number and fold-increase of EPCs/ECs over the initial CD34⁺/VEGFR2⁺ EPCs isolated from nonhuman primate PB. Data represent mean ± SD; n = 10
