Significant increases in skin wound healing rates occur by reducing connexin-mediated communication (CMC). Gap27, a connexin (Cx) mimetic peptide targeted to the second extracellular loop of Cx43, which inhibits CMC, increases migration of human keratinocytes and dermal fibroblasts. To examine the efficacy of Gap27 in a hyperglycemic and hyperinsulinemic in vitro environment, cell migration, gap junction, and Cx hemichannel functionality and cell-substrate adhesion assays were performed on human dermal fibroblasts and diabetic fibroblast and keratinocytes.
