Effects of qiliqiangxin (QL) on cardiac microvascular endothelial cells (CMECs) angiogenesis under hypoxic condition. (A) QL increased the mRNA and protein level of HIF‐1α in hypoxic CMECs (n = 4‐6/group). (B) QL increased the mRNA and protein levels of VEGF in hypoxic CMECs (n = 4‐6/group). (C) QL treatment promoted tube formation of hypoxic CMECs (10×, Scale bar 100 μm) (n = 4/group). (D) Bar graphs of total branching points, loops, tubes and tube length (n = 4/group). Data were expressed as means ± SD. *P < .05; **P < .01
