Attainment of polarity promotes growth factor secretion by retinal pigment epithelial cells: Relevance to age-related macular degeneration
Figure 3. Polarized secretion of PEDF and VEGF in differentiated human RPE cells. Human polarized RPE cells on transwells isolated from 3 different donors preferentially secreted PEDF (A) to the apical side of the tissue and VEGF-A (B) to the basolateral side. The bars represent average of 2 determinations for each donor with variation in each sample <5%.
