FIGURE 1.

Excisional wound healing in 5-Ht1a receptor KO mice (excisional punch biopsy model). The wound tissue sections were prepared 7-days after wounding and Masson’s trichrome staining was performed. Scale bars represented at 500 μm (A,B). Comparative epidermal thickness (μm) between WT and KO group (C,H). Comparative wound length (μm) in WT and KO group (E). Wound area (×10³ μm²) is comparatively bigger in KO group (F), (n = 4 wound images per specimen). Wound cellularity and total cell count (number of cells in wound zone) is comparatively high in KO group (D,G), images represented at 50 μm scale bar (n = 4 images per specimen). Results were presented as mean ± 95 CI (confidence interval). Two-way ANOVA was performed and significance levels were set at ^∗P < 0.05, ^∗∗P < 0.01.
