Distribution of principal cell culture per year. BRECs were the most used in the past, being nowadays replaced by human cells such as HRECs and HUVECs. BRECs: bovine retinal endothelial cells; HRECs: human retinal endothelial cells; HUVECs: human umbilical vein endothelial cells; RF/6a: Rhesus monkey choroid and retinal endothelial cells.
