We describe a new animal model designed to assess the impact of ischemia on wound healing. Eight patterns of arterial lesion in the limb were first tested in 24 Wistar rats. Resection of the external iliac artery down to the femoral artery at the level of the knee was chosen as the reference model and performed on the left limb of 45 rats; the right limb was used as the control. Skin wounds measuring 1.2 x 0.8 cm were created on both feet. Ischemia was assessed by blood flow measurement, which decreases dramatically in the ischemic limb. A significant delay in wound closure with a decrease in wound contraction was observed in the ischemic limb. Myofibroblast quantification showed a significant delay in appearance as well as a decrease in the number of these cells in the ischemic wound. Vascular endothelial growth factor-A appearance and evolution were qualitatively similar in both situations. However, collagen type I mRNA was markedly decreased in ischemic granulation tissue 10 days after wounding. These findings suggest that decreased wound contraction plays an important role in delayed ischemic wound healing, probably due to reduced myofibroblast development and activity.
