Fig 11. Rosiglitazone improves wound healing and subcutaneous fat cell morphology.

Formalin-fixed and paraffin-embedded 13-day wound sections of mock- (a) or rosiglitazone-(b) treated mice (0.5 mg/kg/day) were assessed by AZAN trichrome staining. Collagen deposition is indicated by the blue color. The squares indicate the localizations of the respective magnifications. Scale bars are given in the photographs. Appearance of back wounds upon a 13-day mock (a) or rosiglitazone (b) administration in ob/ob mice is shown in the lower right panels.
