Effects of VEGF inhibitor (Sorafenib) and TGF-β inhibitor (LY364947) in the CT26 or BxPC3 model. a Vascular phenotypes revealed by immunofluorescence staining. Green, CD31 or platelet endothelial cell adhesion molecule (PECAM)-1; red, NG2. b Extravasation of 2 MDa dextran from vasculature. Dextran is shown in green and CD31/PECAM-1 in red. Scale bars = 100 μm. c and d are schemes that explain the different effects of VEGF inhibitor and TGF-β inhibitor on high or low-pericyte coverage tumors (Reproduced from Kano 2009, copyright of Elsevier)
