For example, the option of using TGF-β to enhance the homing capacity of human adipose-derived stem cells (hAMSCs) to GBM and using them as a drug delivery vehicle showed enhanced therapeutic efficacy by an increased number of migrated hAMSCs to target sites, decreased tumor volume, and prolonged survival time in a murine model of GBM [148]. Here, TGFB1 is linked to glioblastoma.
