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%.
