Scaffold/UC-MSCs transplantation restores receptive fertility of uterine scars. a Pregnancies at day 60 post-transplantation in the PBS group, the scaffold group, the UC-MSCs group and the scaffold/UC-MSCs group. Hollow arrows indicate implanted fetuses and black arrows indicate the four pre-marked points surrounding each uterine scar. b Statistical analysis of the total number of fetuses per uterine horn. c Statistical analysis of the number of fetuses implanted within the scarred areas per uterine horn. Data were presented as median and minimum and maximum. ^* P < 0.05 and ^** P < 0.01. PBS phosphate-buffered saline, UC-MSCs umbilical cord-derived mesenchymal stem cells
