Abstract (original English)
Introduction Adipose-derived stem cells (ASCs) have been proven to have tumoricidal effects against hepatic cancer cell lines. However, it appears that exposure to oxidative microenvironment compromises the potential outcome of ASCs in real hepatoma. Herein, we aimed to examine the tumoricidal effects of ASCs under oxidative conditions and to investigate the impact of curcumin priming on ASCs' therapeutic potential. Methods We used human hepatoma (HepG2) cells in a coculture system with unprimed or curcumin-primed ASCs (Cur-ASCs) under H 2 O 2 -induced oxidative conditions. To investigate HepG2 proliferation and death, MTT (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) and annexin V staining assays were performed. To determine the HepG2 migration and invasion potential, the scratch healing and the transwell invasion assays were performed. To evaluate the expression of apoptosis-protein markers, Western blotting was performed. Results Cur-ASCs suppressed HepG2 proliferation, migration, and invasion as well as prompted apoptosis more significantly compared to unprimed ASCs under oxidative conditions. Expressional studies also revealed an obvious decline in the BCL-2/BAX ratio in HepG2 cocultured with Cur-ASCs. In addition, we noticed a marked elevation of apoptosis and senescence in unprimed ASCs compared to Cur-ASCs after coculture experiments, which demonstrate
