Interaction of CD200 Overexpression on Tumor Cells with CD200R1 Overexpression on Stromal Cells: An Escape from the Host Immune Response in Rectal Cancer Patients

Figure 1

(a) Immunohistochemical staining of CD200 in total 140 rectal cancer patients. Representative images (magnification x 60) are provided from different patients with low (on the left) and high scorings (on the right). Brown precipitate indicates positive staining. (b) Semiquantitative scoring of CD200 immunohistochemical staining in patients with rectal cancer and normal mucosa. Scoring was performed as described in the section of Materials and Methods.
