Effects of VEGF and PLA-VEGF on protein expression of α SMA, PIK3Cb, VEGFR2, and PKBa in HESC. a Western blotting images showing the levels of protein expression after stimulation with different concentrations of rVEGF121 and PLA-VEGF microparticles release. b–e Expression levels of α SMA (b), PIK3Cb (c), VEGFR2 (d), and PKBa (e) in HESC; the expression levels normalized with GAPDH expression. Data represented as mean ± S.D., n = 3. Statistical significance (p < 0.05, p < 0.01, p < 0.001) compared (200 and 500 ng of rVEGF121 with the positive control, while days 1, 20, and 30 with PLA-PBS (negative control))
