Immunohistochimecal staining of CD105 in colorectal cancer tissues (CRC), adjacent normal tissues, and normal testis controls. Cytoplasmic CD105 expression in tumor cells: low expression a-a1 and high expression b-b1. CD105 expression in endothelial cells: low expression c-c1 and high expression d-d1. Adjacent normal tissues e-e1. Normal kidney tissues as controls: positive f and negative g
