PATTERNS THE RESTORATION OF SKIN DERIVATI VES IN HOMOIOTHERMIC ANIMALS

It is known that the skin derivatives in homoiothermic animals appear in the early prenatal period of development and do not form during pos tnatal development. However, during skin regeneration, a process of se condary development, it was shown experimentally on eight homoiothermi c animals, in which full-layered fragments of skin were removed from d ifferent morphofunctional regions of skin, that in the skin regenerate s its derivatives are formed: hair, sebaceous and swat glands, and ski n folds. The data obtained suggest that formation of the hair and seba ceous glands requires the presence of special dermal fibroblasts in th e young connective tissue of regenerants, which are capable of inducti on of the potencies of regenerating epidermis for organogenesis.
