Figure 2. GA-hMSC-derived exosomes enhance GSC proliferation and clonogenicity in vitro.
(A, B) Proliferation assay demonstrating a significant dose-dependent increase in GSC proliferation with the addition of matched (A) and un-matched (B) GA-hMSC-derived exosomes. * p<0.01, ** p<0.001, paired t-test (C, D) Clonogenicity assay demonstrating a significant (*p< 0.05) increase in GSC neurosphere formation with the addition of matched (C) and un-matched (D) GA-hMSC-derived exosomes. In un-matched experiments GSC-7-2 was treated with exosomes and ED-CM from GA-hMSC-247 and GSC-11 was treated with exosomes and ED-CM from GA-hMSC-230. ED-CM: exosome depleted-conditioned media.
