RESPONSE OF MAMMALIAN EPIDERMAL MELANOCYTES IN CULTURE TO HORMONES

[摘要] Four hormones aMSH [melanocyte-stimulating hormone], acetylcholine, norepinephrine, and melatonin have been added to guinea pig epidermal melanocytes grown in culture. No changes in either the cell morphology or melanin granule activity were observed when concentrations of the hormones which have a known effect on the skin color of amphibians were used.
