Planimetric assessment of (a) the wound closure rate and biomechanical assessment, n = 6 mice per group, and of (b) healed skin in diabetic (Leprdb/J) mice treated with 5% topical losartan, n = 3–5 mice per group. (c) Laser Doppler perfusion imaging of wound area blood flow, n = 5 mice per group. (d) Planimetric assessment of the wound closure rate in Leprdb/J mice treated with different doses of valsartan and losartan gels applied 7 days after wounding, n = 7–8 mice per group. (e) Altered mRNA expression of wound angiotensin receptors and TGFβ isoforms in Leprdb/J mice treated with losartan 1% and valsartan 1%, n = 3–5 mice per group. (f) Kaplan-Meier analysis of complete wound closure in Leprdb/J mice treated with 1% valsartan n = 7–8 mice per group. *P < 0.05, **P < 0.01, ***P < 0.001, +++P < 0.001 los 1% versus val 1% early stage, +P < 0.05 los 1% versus val 1% late stage of wound healing. AT1R, angiotensin II type 1 receptor; TGFβ, transforming growth factor-beta.
