Reactive Oxygen Species Induce Endothelial Differentiation of Liver Cancer Stem-Like Sphere Cells through the Activation of Akt/IKK Signaling Pathway
Figure 2
Cancer stem-like sphere cells differentiate to endothelial cells. Cells were cultured in MCDB131 endothelial medium with or without VEGF (10 ng/ml) for two generations. Expressions of endothelial markers CD31 (a) and vWF (b) were detected with immunofluorescence staining. The cell nuclei were counterstained with DAPI (200 ×). (c) Formation of capillary-like structure on Matrigel (100×). (d) A number of formed tubes were calculated. The data were presented as (). vs. Hep G2 group.
