Healing of cutaneous wounds in wild type (WT) and PPARΓ haplodeficient (PPARΓ+/-) mice. A: Closure of wounds expressed as percentage of non-epithelialized area. Surface of wound measured immediately after surgery was taken as 100%. B: Number of capillaries stained for CD31 antigen in the muscles located under healthy skin (day 0) and under wounded skin, 3 and 11 days after surgery. C: Representative pictures showing CD31 immunostaining. Fluorescence microscopy. Mean + SEM. N = 4-5, ***p < 0.001 versus day 0.
