Abstract Normal human melanocytes were cultured selectively with F12 culture medium supplemented with growth hormones, phorbol ester and 1\% of fetal calf serum. The estrogen receptors were analyzed using hydroxylapatite-column assay with tritiated 17-beta-estradiol as the binding ligand. Phenol red- free medium was used when the changes in cell numbers, melanin content and tyrosinase were assessed after incubating with physiological concentration of 17-beta estradiol (10(-12) and 10(-9) M). It was found that the melanocytes contained both cytosol (5.42 +/- 1.11 fmol/mg protein) and nuclear (59.13 +/- 17.12 fmol/mg protein) estrogen receptor. In response to estradiol, the cell number increased but both the melanin content and the tyrosinase activity decreased in a dose related pattern. These data suggested the presence of estrogen receptor with biological function in normal human melanocytes.
