[Variations in the completeness of skin regeneration during post-traumatic regeneration]

The healing of the full-thickness skin wounds on the abdomen and the back of hedgehogs was investigated. The wound healing on the abdomen proved to result mainly from the wound contraction. In most cases a small regenerated area containing new hair and sebaceous glands was formed in the centre of the wound. Contraction of the wound was practically absent on the back and its healing occurred chiefly by new tissue formation; due to this vast regenerated areas were formed in the wound. Connective tissue frame-work of the regenerated area on the abdomen and the back resembled intact derma by fiber distribution.
