Effect of coculture on VEGF signaling pathway-related proteins. (a)–(d) The effect of coculture of HA-1800 and hBMEC on VEGF protein level detected by Western blotting and statistical analysis of Western blotting. Phosphorylation levels of the indicated kinases ERK1/2 and Akt were also quantified by densitometry.
