The hAMSC-SBE4-TRAIL delivery system has a potential clinical applications for GBM therapy. Our work sought to hAMSCs which augment the expression of TRAIL under the trigger of TGF-β-secreting primary GBMs and avoid unspecific TRAIL secretion into non-target cells. The results on the controlled release of the suicide gene delivery system demonstrate a significant improvement for the clinical utility of biological strategy to treat brain cancers, especially for the patients in whom tumor mass express elevated level of TGF-β
