GHK-Cu (Glycyl-L-Histidyl-L-Lysine copper complex) is a naturally occurring tripeptide-copper complex first isolated from human plasma. It is found in saliva, urine, and various tissues and its concentrations in plasma decline with age. The compound has been extensively studied in cell biology and wound-healing research for its interactions with copper-binding proteins and its reported influence on gene expression profiles.
Research published over several decades indicates that GHK-Cu modulates a broad array of biological processes at the cellular level. Studies have examined its effects on fibroblast activity, extracellular matrix remodeling, antioxidant enzyme expression, and angiogenesis-related signaling pathways. Its small size and copper-chelating structure facilitate cellular uptake in laboratory models.
As a research compound, GHK-Cu is investigated in contexts ranging from tissue biology to skin model research and gene regulation studies. It is intended strictly for laboratory use and is not approved as a pharmaceutical or therapeutic agent.
The areas where this compound appears in the published research literature.
In cell culture systems, GHK-Cu is typically applied to fibroblast or keratinocyte monolayers at nanomolar to micromolar concentrations. Researchers measure outcomes such as cell proliferation rate, migration assay results, collagen secretion (via ELISA or hydroxyproline assay), and gene expression changes via quantitative PCR or transcriptomics.
Animal models of wound healing have been employed to assess how GHK-Cu applied to wound sites influences closure rates, tissue architecture, and collagen deposition histologically. These models help contextualize the in vitro findings within a more complex biological environment.
