HSE-nanogel demonstrated a significant in vivo wound contraction activity alongside improving histopathological abnormalities. Mechanistically, HSE-nanogel upregulated the wound antioxidant status through increasing the levels of reduced glutathione (GSH) and catalase activity. Moreover, HSE-nanogel suppressed the wound inflammatory responses by diminishing the expressions of NF-ĸB, TNF-α, and IL-6.
