Migration analysis by scratch assay. Representative fields of images between hDPSCs cultured in E8 and serum-containing medium (SCM) are shown, with detections performed at a 0 h, b 24 h, and c 48 h under a microscope. d Statistical analysis of the comparison between E8 and SCM in the scratch length at 0 h, 24 h, and 48 h (n = 5). *p < 0.05, **p < 0.01
