In Vitro	β-Neo-Endorphin (0-20 μM, 20 h) stimulates wound healing in human keratinocytes[2]. β-Neo-Endorphin (promotes wound healing through activation of the Erk1/2 signaling pathway in human keratinocytes[2]. β-Neo-Endorphin (0-20 μM, 12 h) stimulates keratinocyte migration through activation of metalloproteinase (MMP)-2 and -9[2]. β-Neo-Endorphin (12 h) stimulates migration in the fibroblast[2]. Cell Viability Assay[2] Cell Line: Human keratinocytes (HaCaT) Concentration: 0, 5, 10 and 20 μM Incubation Time: 20 h Result: Significantly increased the wound closure. Had no observable effect on cell viability. Western Blot Analysis[2] Cell Line: Human keratinocytes (HaCaT) Concentration: 0, 5, 10 and 20 μM Incubation Time: 12 h Result: Activated Erk1/2, phosphorylated P90RSK and Elk-1, showed significant upregulation of MMP-2 and -9 expression.
