Differential retinoid binding in chick pigment epithelium and choroid.
A receptor for retinol but not for retinoic acid was demonstrated to be present in fresh chick embryo pigment epithelium and in pigment epithelial cells grown in tissue culture. In contrast, chick choroid was found to possess receptors for both retinoic acid and retinol.
