Fig. 1From: Glioma-associated mesenchymal stem cells-mediated PD-L1 expression is attenuated by Ad5-Ki67/IL-15 in GBM treatmentIdentification of MSCs derived from human glioma tissues. A and B Adherent growth patterns and fibroblastic morphology of GA-MSCs cultured in MSC media (× 100, scale bars = 1000 µm). C Immunofluorescence showed that GA-MSCs expressed MSC specific markers CD44 and CD105 (× 400, scale bars = 500 µm)Back to article page
