Urodele amphibians, such as the axolotl (Ambystoma mexicanum), have the unique faculty among vertebrates to regenerate lost appendages (limbs and tail) and other body parts (apex of the heart, forebrain and jaw) after amputation. Interestingly, axolotls never seem to form scar tissue at the site of amputation once regeneration is completed. Before now, very few studies were directly focused on the description of the events happening during wound healing after a skin injury in salamanders. In this paper, we directly investigated skin wound healing after excisional wounding which removed the epidermis, dermis and basement membrane in the axolotl. Axolotls were wounded with a 1.5-mm skin biopsy punch. Results show rapid re-epithelialization of the wound within 8 hrs after wounding. Histological analysis of wound healing confirmed the absence of tissue fibrosis throughout the process and shows that skin integrity is re-established by 90 days after wounding. Results also reveal the absence of neutrophils in the wound area, suggestive of a lack of or low inflammatory response. The expression of proteins central to wound healing seemed different than in mammals as α-smooth muscle actin was absent and transforming growth factor β-1 was only transiently expressed during wound healing in the axolotl. Finally, subcutaneous injections of bleomycin were performed to verify whether the induction of scar tissue was possible in axolotls. Surprisingly, results show that axolotls are not resistant to bleomycin-induced tissue fibrosis, but the resulting scar tissue does not seem to contain significant amounts of collagen.
