Effect of cyclic stretch (CS) and static stretch (SS) on the expression of VEGF receptor 1 (VEGFR-1) and 2 (VEGFR-2). Rat coronary microvascular endothelial cells (RCMECs) were cultured under nonstretch control (CON) or stretch conditions for 1, 6, 18, and 24 h. Total protein (50–75 μg/lane) isolated from cells was analyzed for VEGF-Rs and GAPDH. Quantitative densitometry analysis is expressed as means ± SE (3–4 experiments/group). Expression levels of VEGFR-1 and VEGFR-2 were normalized to those of GAPDH and are shown as fold increases over control. Representative Western blot images are shown above each graph. *P ≤ 0.05 and **P ≤ 0.01, statistically significant increases compared with control.
