in fibroblast culture models it stimulates collagen, elastin, and glycosaminoglycan synthesis at picomolar to nanomolar concentrations (10 to 10 M), and modulates metalloproteinase (MMP-1, MMP-2, MMP-9) activity and their inhibitors (TIMP-1, TIMP-2), functioning as a general regulator of extracellular matrix remodeling ( Mechanistic research establishes that GHK activates TGF- and integrin 1 pathways during tissue repair, attracts immune and endothelial cells to wound sites, and restores gene expression patterns toward a healthier fibroblast phenotype in models of aging and radiation damage ( A 2018 review in IJMS characterizes its role in collagen production, nerve outgrowth stimulation, and dermal stem cell marker expression ( For Research Use Only
Although all EDS disorders are inherited, the specific etiology depends on the EDS type
Topical Applications In rat and mouse skin models, topical GHK cu appears most commonly as an active ingredient in cream or gel formulations applied directly to wounds or shaved dorsal skin
