Immunostaining of CD31 and high molecular weight melanoma associated antigen (HMW-MAA) in vascularized rabbit corneas.

<p>Photos taken at 1, 2, and 4 weeks after the induction of corneal NV in no treatment group and 1, 2, and 4 weeks after bevacizumab injection in early and late treatment groups. Staining of CD 31 surrounded by HMW-MAA was found at week 2 and 4 in no treatment group, and week 1, 2, 4 after bevacizumab injection in late treatment group, which demonstrated the presence of pericytes around the vascular endothelial cells. Scale bar: 40 μm. Red: CD31; Green:HMW-MAA; Blue: Hoechst33258 which stains nucleus.
