Fig. 4From: Decreased VEGF-A and sustained PEDF expression in a human retinal pigment epithelium cell line cultured under hypothermiaDehydrogenase activity in ARPE-19 cells at each adjusted temperature. Cellular metabolism evaluated by dehydrogenase activity significantly decreased as the culture temperature decreased. Data are presented as mean ± SD (n = 5); **P < 0.01.Back to article page
