VEGFA and uveal melanoma: The secretion of VEGF by uveal melanoma cells (1486 ± 243 pg/106 cells/24 h) was also significantly greater than that by normal uveal melanocytes (67.4 ± 4.8 pg/106 cells/24 h) (P < 0.05), indicating that uveal melanoma cells have a much higher constitutively secretion of VEGF (21-fold) as compared with their normal counterparts.
