TNFSF10 and glioblastoma: Interaction between bi-functional MSCs and GBM cells produced a significant apoptotic effect on cell aggregates (59 ± 5%), compared to both mTRAIL MSCs (32 ± 7%; p < .001) and non-expressing TRAIL ones, EV MSCs and GD2 tCAR MSCs (9 ± 3% and 15 ± 4%, respectively, p < .001; Fig. 5b, smooth columns).
