Scarless Wound Healing

Abstract

Scarring results from injuries and disease in mammalian adults and can cause pain and loss of function in the afflicted tissues. This negative aspect of wound repair is not always true for certain amphibians and during fetal development of mammals. Based on this knowledge, scientists and clinicians are investigating the mechanisms and growth factors that contribute to or deter a suitable environment for wound healing. This review summarizes these aspects and challenges for scarless repair.
