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.

We used human hepatoma (HepG2) cells in a coculture system with unprimed or curcumin-primed ASCs (Cur-ASCs) under H₂O₂-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 …
