Abstract

Autologous fat grafting procedures have noted a markedly increased frequency, not only for cosmetic purposes, but also for deformities after head and neck cancer and breast cancer surgery. Carcinogenesis is always a major concern in cell therapy-related issues. However, there is no literature discussing this issue in head and neck squamous cell carcinoma patients. To evaluate the interaction of tongue cancer cells and adipose-derived stem cells, we performed a series of in vitro experiments. Our results demonstrated that cisplatin significantly reduced the viabilities of SCC‑25 and CAL‑27 cells in a concentration-dependent manner, but it had low cytotoxicity in cisplatin-resistant CAL‑27 (CAR) cells. There was no significant difference in terms of viability among the SCC‑25, CAL‑27, and CAR cells in the adipose-derived stem cell conditioned medium and control groups. There was also no significant difference in terms of cell migration as determined by wound healing assay of SCC‑25, CAL‑27, and CAR cells between the adipose-derived stem cell conditioned medium treatment and control treatment. Importantly, the adipose-derived stem cell conditioned medium attenuated cisplatin-triggered cell death in the SCC‑25 and CAL‑27 cells. Moreover, adipose-derived stem cell conditioned medium markedly inhibited cisplatin-induced apoptotic cell death (sub‑G1 phase) in the CAL‑27 cells. Western blot analyses indicated that cisplatin-induced reductions in pro‑caspase‑3, pro‑caspase‑9, phospho-BAD, phospho-IGF-1R, phospho-AKT, and phospho-ERK in CAL‑27 cells were reversed by adipose-derived stem cell conditioned medium supplement. Taken together, we provide evidence that adipose-derived stem cell conditioned medium protects CAL‑27 cells from cisplatin-induced cell death, possibly through upregulation of the IGF-1R/AKT/ERK signaling pathway.
