For example, Qiu et al. coincubated a drug (cabazitaxel, CTX) for the treatment of oral squamous cell carcinoma with tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) gene-modified MSCs and successfully purified exosomes loaded with CTX/TRAIL (MSCT-EXO/CTX). This evidence concerns the gene TNFSF10 and oral cavity squamous cell carcinoma.
