GHK-Cu — Copper Tripeptide Complex for Regenerative Research
GHK-Cu (Glycyl-L-histidyl-L-lysine copper) is a naturally occurring copper-binding tripeptide identified in human plasma by Pickart & Thaler (1973). Over 60 peer-reviewed publications document its roles in wound healing, collagen synthesis, anti-inflammatory signaling, and stem cell recruitment.
Mechanism of Action
GHK-Cu delivers copper ions essential for lysyl oxidase, SOD, and tyrosinase. It upregulates ECM assembly genes while downregulating metalloproteinases. Genome-wide analysis (Gene, 2014) revealed modulation of 4,000+ genes across tissue remodeling, inflammation, and antioxidant pathways.
Key Research Areas
- Wound Healing: Accelerates fibroblast migration and wound closure in scratch assay models. Enhanced granulation tissue and wound tensile strength in vivo.
- Collagen & ECM Biology: Stimulates type I/III collagen, elastin, and proteoglycan synthesis while organizing collagen fibril architecture.
- Anti-Inflammatory: Suppresses IL-6, TNF-α, TGF-β1 and reduces oxidative damage markers in tissue injury models.
- Stem Cell Recruitment: Promotes recruitment and differentiation of mesenchymal stem cells for endogenous regenerative mechanisms.
