Figure 6From: Mesenchymal Stromal Cells Promote Tumor Growth through the Enhancement of NeovascularizationPresence and differentiation of MSCs in the tumors. (A) GFP-MSCs present and randomly distributed in the tumors on day 21 generated by co-injection of B16-LacZ cells and GFP-expressing MSCs. (B) GFP-MSCs closely localized to tumor vessels coexpressed the endothelial marker CD31, but did not coexpress the pericyte marker α-SMA.Back to article page
