Melatonin Stimulates Epithelium Migration in Wound Models In Vitro and In Vivo
- 4 Downloads
We studied the effect of bovine brain gangliosides, individual ganglioside GM1, and melatonin on the rate of wound closure under in vitro conditions and the effect of melatonin on the rate of wound healing under in vivo conditions. It was shown that bovine brain gangliosides and melatonin reliably increased cell migration in the experimental wound model. This effect was detected when the cell cultures were treated with the test preparations after wound infliction and when the cultures of human keratinocytes were pretreated before wounding. Analysis of the effect of melatonin on the rate of wound healing in vivo showed that melatonin accelerated this process, especially at the middle stages corresponding to the proliferation phase (days 3-6 after surgery). Histological analysis revealed intensification of epidermal cell proliferation at the edges of the wound starting from day 4 after surgery.
