Figure 1: Quantification of vascular endothelial growth factor (VEGF) and pigment epithelial derived factor (PEDF) protein after exposing with various concentration of rAPN. (a) Quantification of VEGF in the conditioned medium showed a significant decrease in rAPN exposed retinal pigment epithelial cells when compared to control (*statistically signifi cant compared to control). (b) Quantification of PEDF in the conditioned medium in rAPN exposed retinal pigment epithelial cells
