Hair Regeneration under Stress

Abstract

The phenomenon of wound-induced hair neogenesis in adult mice and rabbits offers a tantalizing window into the mechanisms of regeneration. By comparing wounds in mice and several rat strains, Guerrero-Juarez et al. attempted to identify factors that may contribute to the failure of wound-induced hair neogenesis to occur in the rat. In addition to biochemical, cellular, and molecular variation, worthwhile comparisons could include the magnitude, distribution, and source of tensional forces within the wound environment.
