VARIABLE COMPLETENESS OF SKIN REGENERATIO N IN WARM-BLOODED ANIMALS

It is generally accepted that skin regeneration in warm-blooded animal s always results in scar formation. Still we have found that the skin regenerated in place of full-thick square skin wounds often resemble t he normal one rather that the connective tissue scar by structure. Mor phological variability of the skin regenerates proved to depend on the wound location and the animal species. The possibility of formation o f the skin derivatives (hair follicles, fat and sweet glands, skin fol ds) has been shown. A classification of the skin regenerates has been proposed. Numerous examples demonstrate the skin ability to give rise to organ-specific regenerates with the morphological features specific for the wound site.
