ABSTRACT: Objective
Mesenchymal stem cells (MSCs) derived exosomes offers several advantages as a cell-free therapeutic agents. In this study, Umbilical cord mesenchymal stem cells exosomes (UC-MSCs-exos) effects on oral squamous cell carcinoma (OSCC) cell line was evaluated.Methods
UC-MSCs-exos were isolated and co-cultured with OSCC cells and their impact on OSCC was explored by various tests. Comet assay and western blot for cleaved caspase-3 and immunocytochemistry for caspase-8 were used for apoptosis assessment. HO-1 and Nrf2 were used to determine antioxidant levels. Tumor necrosis factor-α and interleukin-6 were assessed as inflammatory biomarkers. HOX transcript antisense intergenic long noncoding RNA (HOTAIR) expression was also evaluated.Results
In a dose-dependent manner, UC-MSCs-exos reduced the levels of pro-inflammatory cytokines (IL-6 and TNF-α) and induced apoptosis of OSCC in vitro. Meanwhile, we found that UC-MSCs-exos downregulate HOTAIR.Conclusion
UC-MSCs-exos conferred a suppressive role on OSCC in vitro, highlighting a promising therapeutic role. However, the exact potentially involved molecules and molecular mechanisms need to be investigated in further studies.
