Effects of MSC mitochondria on GSCs metabolic response to TMZ (A, B) GSC mitochondrial mass and ROS production. FACS analysis of MitoTracker and MitoSox-labeled GSCs after the acquisition of MSC mitochondria and TMZ treatment (24 hr). (A) Mitochondrial mass. (B) ROS production. (A, B) Representative experiments and relative MFI values (mean ± SEM; n=3). One-way ANOVA, *p < 0.05. (C) Expression of Cytochrome c oxidase IV (COX IV). Representative Western blot with the corresponding membrane (MW markers in kDa) as shown in Fig. 3H.

ARTICLE ABSTRACT

Mitochondria acquired from MSCs enhance the chemoresistance of GBMs. The discovery that they also generate metabolic vulnerability in GSCs paves the way for novel therapeutic approaches.
