 Effect of pigment epithelium‐derived factor (PEDF) on cell proliferation. Primary human umbilical vein endothelial cells (HUVECs) and SO‐Rb50 cells were treated with PEDF at concentrations indicated for 72 h. The viable cells were quantified by MTT. Data represents absorbance as percentages of respective controls (mean ± SD, n = 3), and values statistically different from the control are indicated (*P < 0.05). PEDF inhibited proliferation of HUVECs in a dose‐dependent manner, but had no effect on proliferation of SO‐Rb50 cells.
