Fig. 3. CGRP promotes corneal hemangiogenesis and lymphangiogenesis in vivo.
A single figure-eight intrastromal suture was placed on mouse cornea and CGRP (50μΜ) or PBS control was given topically three times daily for 14 days (n = 5). (A) Representative images of slit lamp photography. (B) Representative images of corneal whole mount stained with CD31 (Blood vessels, green) and LYVE-1 (Lymph vessels, red), × 100 magnification, dashed line indicates the limbus. (C, D) Quantification of corneal neovascularization (CNV) area (CD31, C) and Lymph vessel area (LYVE-1, D) at day 14 after. (E) mRNA level of VEGF-A in the cornea was assessed. *p < 0.05, **p < 0.01, ****p < 0.0001, unpaired t-test.
