Abstract

The lectin Artin M has been shown to accelerate the wound-healing process. The aims of this study were to evaluate the effects of Artin M on wound healing in the palatal mucosa of rats and to investigate the effects of Artin M on transforming growth factor beta (TGF-) and vascular endothelial growth factor (VEGF) secretion by rat gingival fibroblasts. A surgical wound was created on the palatal mucosa of 72 rats divided into three groups according to treatment: CControl (nontreated), AArtin M gel, and VVehicle. Eight animals per group were sacrificed at 3, 5, and 7 days postsurgery for histology, immunohistochemistry and determination of the levels of cytokines, and growth factors. Gingival fibroblasts were incubated with 2.5g/mL of Artin M for 24, 48, and 72 hours. The expression of VEGF and TGF- was determined by enzyme-linked immunosorbent assay. Histologically, at day 7, the Artin M group showed earlier reepithelialization, milder inflammatory infiltration, and increased collagen fiber formation, resulting in faster maturation of granular tissue than in the other groups (p<0.05). Artin Minduced cell proliferation in vivo and promoted a greater expression of TGF- and VEGF in both experiments (p<0.05). Artin M was effective in healing oral mucosa wounds in rats and was associated with increased TGF- and VEGF release, cell proliferation, reepithelialization, and collagen deposition and arrangement of fibers.
