Model: Full-thickness skin defect 12 mm in diameter on the back of diabetic mice (chronic ulcer model) and 8 mm full-thickness defect within a 10 mm tattooed ring on the back of healthy guinea pigs (acute ulcer model)
In diabetic mice at 14 days the silk-elastin group showed a significantly higher epithelialisation rate than all other groups (about 1.5-fold) and a significantly larger granulation tissue area than control and Intrasite gel groups; at 21 days epithelialisation remained higher than control and Intr…
