[Patterns in the restoration of skin derivatives in warm-blooded animals]

It is known that the skin derivatives in homeothermic animals appear in the early prenatal period of development and do not form during postnatal development. However, during skin regeneration, a process of secondary development, it was shown experimentally on eight homeothermic animals, in which full-layered fragments of skin were removed from different morphofunctional regions of skin, that in the skin regenerates its derivatives are formed: hair, sebaceous and sweat glands, and skin folds. The data obtained suggest that formation of the hair and sebaceous glands requires the presence of special dermal fibroblasts in the young connective tissue of regenerants, which are capable of induction of the potencies of regenerating epidermis for organogenesis.
