Fig. 5From: Differential expression of VEGFR2 protein in HER2 positive primary human breast cancer: potential relevance to anti-angiogenic therapies a, b Invasive carcinomas of the breast, triple-negative (TNBCs), representative of the majority of cases in Fig. 2c (orange box). Invasive ductal (a) and invasive lobular (b) carcinomas of the breast, featuring fairly high CD34+ tumor vessel counts (right panels). In both cases only a rare tumor stromal vessel shows immunoreactivity for VEGFR2 (black arrows, left panels). Original magnification ×200Back to article page
