Abstract
Wound healing is a complex process in which injured skin and tissues repaired by interaction of a complex cascade of cellular events that generates resurfacing, reconstitution and restoration of the tensile strength of injured skin. It follows β-catenin, extracellular signal regulated kinase (ERK) and Akt signaling pathways. Aegle marmelosL., generally known as bael is found to act as anti-inflammatory, antioxidant and anti-ulcer agent. Furthermore, studies have demonstrated that this Indian traditional medicinal plant, A. marmelos flower extract (AMF) was used for wound injury. Henceforth, the current study was investigated to ascertain the effect of its active constituents in vitro wound healing with mechanism involve in migration of cells and activation of β-catenin in keratinocytes, inhibition of PGE2 in macrophages and production of collagen in fibroblasts. We have taken full thickness wound of rats and applied AMF for 2 weeks. Cutaneous wound healing activity was performed using HaCaT keratinocytes, Hs68 dermal fibroblasts and RAW264.7 macrophages to determine cell viability, nitric oxide production, collagen expression, cell migration and β-catenin activation. Results shows that AMF treated rats demonstrated reduced wound size and epithelisation was improved, involved in keratinocytes migration by regulation of Akt signaling, beta-catenin and extracellular signal-regulated kinase (ERK) pathways. AMF and its active constituent’s increased mRNA expression, inhibited nitric oxide, PGE2 release, mRNA expression of mediators in RAW 264.7 macrophages and enhances the motility of HaCaT keratinocytes in vitro wound healing of rats.
