Healing of incised wounds in the backs of mice was studied to establish criteria that would allow the timing of stages during cutaneous wound healing. Starting from day 4 after the incisions were made, three mice were killed every 3 days until day 40. Sections from wounds were stained with hematoxylin-eosin, a reticulin procedure, and picrosirius red. Unstained sections were used for blue autofluorescence. The significance of the findings from the ultraviolet study was limited, but the picrosirius red-polarized light procedure was found to be useful for estimating the age of the repair process as polarization colors of greater wavelengths progressively increased with the age of the lesion
