Figure 2. NGF increased the expression of VEGF in Müller cells. Müller cells were treated with 100 ng/ml of nerve growth factor (NGF) compared with an equal amount of bovine serum albumin (BSA) control. After 12 or 24 h, vascular endothelial growth factor (VEGF) protein expression in the supernatants was significantly increased in the NGF-treated group according to the enzyme-linked immunosorbent assay (ELISA). Importantly, the VEGF increase after 24 h was significantly higher than that after the 12 h treatments. There was no statistically significant difference between 12 and 24 h in the BSA treatment group with a p value equal to 0.0644. n=6, *p<0.05, *** p<0.001.
