The involvement of glucocorticoid hormones in the appearance of white spots during embryogenesis in domesticated gray rats was studied. It was shown that in fully pigmented gray rats, prenatal stress and exposure to dexamethasone on days 12-14 of gestation elicited a delay in the migration and development of melanoblasts in embryos. This led to a fourfold increase in the number of offspring with depigmentation on the ventral side of the body. It was also demonstrated that in adult offspring of mothers treated with dexamethasone, the response of the hypothalamo-pituitary-adrenal axis to the emotional stress was lower compared to the controls. The role of glucocorticoids in the appearance of coat depigmentation under animal domestication is discussed.
