From: IGF-1C domain–modified hydrogel enhanced the efficacy of stem cells in the treatment of AMI
CS-IGF-1C hydrogel augmented the proangiogenic capacity of hP-MSCs. a Scratch wound healing assay of HUVECs treated with CS-IGF-1C hydrogel for 0 and 12 h. *P < 0.05 versus PBS; scale bar represented 200 μm. b The migration ratio statistics of HUVECs in each group. c Representative images of myocardium sections stained for CD31 (red) at day 14. Scale bar, 100 μm. d Quantitative analysis of CD31 immunostaining in each group. The number of capillary vessels was counted in three randomly selected areas. Data are expressed as mean ± SEM. *P < 0.05 versus PBS; **P < 0.01 versus PBS; #P < 0.05 versus PMSC. e Expression levels of VEGF by RT-PCR in each group on day 14. Data are expressed as mean ± SEM. *P < 0.05 versus PBS; **P < 0.01 versus PBS
