An evaluation of regenerative capacity of skin at various locations on the body of the adult newt. (a) Schematic drawing of the site of skin removal. A 4–9 mm² square-to-oval shaped piece was excised from the dorsal skin of the head, trunk and limbs (forelimbs and hind limbs), as well as from abdominal skin, including skin around the cloaca (white squares). In the dorsal skin of the trunk, an excision was made within the area between the top (dorsal midline) and the boundary with orange abdominal skin. In the abdominal skin (i.e., belly skin), the plain orange area and the black-orange patterned area were separately examined. (b) Summary of results at 180 days after operation. * and ** show the results at 720 days after operation; each was 100% (n = 2) (for details, see the main text). N: not applicable.
