Increased Expression of VEGF and CD31 in Postradiation Rectal Tissue: Implications for Radiation Proctitis
Figure 2
Rectal mucosa immunostained (a, b) with anti-VEGF antibody (M7273; Dako, Glostrup, Denmark) and (c, d) with anti-CD31 antibody (MO823; Dako, Glostrup, Denmark). Microvasculature was demonstrated by CD31 immunostaining of the vascular endothelial cells while VEGF was detected in endothelial cells and in few stroma cells showing cytoplasmic staining.
