Fig. 5From: Evaluation of anti-tumorigenic activity of BP3B against colon cancer with patient-derived tumor xenograft modelSuppression of angiogenesis by BP3B in PDTX model. To measure the status of tumor angiogenesis in BP3B-treated tumors, immunofluorescence analysis of CD31 was performed. CD31 positive cells were visualized into red and nuclei were stained with DAPI (blue). The intensity of image was quantified with ImmunoRatio software. Scale bars are 50 μm. * p < 0.05Back to article page
