Lenti-CGRP ameliorated the proliferative tube formation but had no effect on cell migration under high glucose conditions. a Representative images of the Matrigel assay. The cells were pretreated with 25 mM or 50 mM glucose for 3 days. The data are shown as the fold changes compared to the 25 mM-treated control group and are expressed as the mean ± SEM, *p < 0.05. Scale bar = 200 μm. b Typical images of the transwell assay after 24 h glucose treatment. The cells were pretreated with 25 mM or 50 mM glucose for 3 days. The migrated cells were stained by crystal violet. Migrated cells in five random fields from each group were counted in Image-Pro Plus 6.0 by under 200 × magnification. Scale bar = 200 μm. The data are shown as the mean ± SEM, *p < 0.05
