Angiogenesis in wound healing at early stages across treatment groups. (A) Representative images of newly formed blood vessels (marked by black arrows) in wound tissue sections from LLC hydrogel, SDF-1α/LLC, and PHMB, and control groups at days 3 and 7 post-injury (H&E stain; 40× magnification; scale bar = 100 μm). All images are transverse sections. (B) Quantification of angiogenesis (vessels/field) from ten random fields per sample. Data are shown as mean ± SEM (n = 5 per group). Statistical analysis was conducted using one-way ANOVA followed by Tukey’s post hoc test (*P < 0.05, **P < 0.01, ***P < 0.001, and ns = non-significant).
