[Regeneration of mammalial plantar skin]

Two sole tubers of rat's hind leg were excised together with the surrounding skin and one of the hind tubers of hind and fore legs in hedgehogs were excised without the surrounding skin. During healing the skin wounds in rats and hedgehogs new skin proved to form with the papillary layer typical of the sole skin. In hedgehogs the new skin covered the regenerated sole tuber; in rats the sole tubers failed to regenerate.
