Fig. 5From: Assessment of HIF-1α expression and release following endothelial injury in-vitro and in-vivoTime course of the levels of intracellular HIF-1α (a) and VEGF mRNA (b) after a scratch assay in vitro. HIF-1α was measured by ELISA and VEGF mRNA by qPCR. HIF-1α levels are expressed as pg/mg protein and VEGF mRNA levels as arbitrary units versus the uninjured samples. Data are the mean ± SEM of 6 samples. *P < 0.05, P** < 0.01 and ***P < 0.001Back to article page
