Abstract (original English)
Objective Human adipose-derived mesenchymal stem cells (ADSCs) have the potential to be applied to solid organ treatments. However, tissue regeneration is limited by the death of transplanted cells. Ischemia is the main cause of the poor outcome. This study aimed to investigate the effect of berberine (BBR) on ADSCs after fat grafting. Methods The antioxidant BBR on apoptosis and autophagy of ADSCs in vitro ischemia model was induced by hypoxia and serum deprivation (HY/SD). The autophagy promoter rapamycin and autophagy inhibitor 3-MA were incubated separately to investigate the crosstalk between autophagy and apoptosis. Pathway inhibitors further verified whether the autophagy and apoptosis were regulated by AMPK/mTor signaling pathway. Fat survival, fibrosis, level of inflammatory cell infiltration, and the effect of angiogenesis after BBR treatment were observed in vivo. Results BBR could reduce ROS production and reverse the decreasing cell survival rate. HY/SD would induce apoptosis and autophagy in ADSCs, and BBR could alleviate these processes. After interfering with the level of autophagy, we also proved that apoptosis was regulated by autophagy and changed accordingly. The results also indicated that BBR could protect against autophagy and apoptosis of ADSCs through AMPK/mTor pathway. The treated human-derived adipose tissue was transplanted into BALB/c nude mice, and
