The study of the epidermis and derma histogenesis, including its epigenetic regulation, is an actively developing field of histology and embryology. The results of the study can elucidate the mechanisms of pathogenesis of some skin diseases of unknown etiology. Wnt signaling is a key regulator of the main morphogenetic processes — cell proliferation and differentiation. Downstream of Wnt signaling is carried out by canonical and non-canonical pathways. Impairments of Wnt signaling in prenatal and postnatal development lead to degenerative and tumor diseases of the skin and hair. Clinical manifestations of the prenatal disorders of skin development epigenetic regulation in the period may appear long after the birth. Identification of factors that disturb the regulation of morphogenetic processes is an important task for investigators. It was found out that activation of the mother’s immune system in the early pregnancy resulted in the development of transient alopecia in the offspring of mice. There was the correlation established between the disorders of epidermal and dermal histogenesis and alopecia as well as the development of regional dysmorphogenetic changes in the skin, which indicate the need to study the rates and features of skin development in various parts of the body.
