miRs-126/126* inhibit erythroid colony formation of CD34⁺ EB cells. (A) Dox treatment induced miRs-126/126* expression in day 15 CD34⁺ EB cells. (B) miRs-126/126* inhibit CFU-E capacity of CD34⁺ EB cells. Data are mean ± SD (n = 4). **P < .01. (C) Hematopoietic and endothelial gene expression in CD34⁺ EB cells. Expression values are relative to cells without Dox treatment. *P < .05.
