[Variability in the completeness of posttraumatic skin regeneration in warm-blooded animals]

It is generally accepted that skin regeneration in warm-blooded animals always results in scar formation. Still we have found that the skin regenerated in place of full-thick square skin wounds often resemble the normal one rather than the connective tissue scar by structure. Morphological variability of the skin regenerates proved to depend on the wound location and the animal species. The possibility of formation of the skin derivatives (hair follicles, fat and sweet glands, skin folds) 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.
