The human peptide GHK and its copper complex GHK-Cu play a broad role in tissue repair and regeneration, with benefits for skin, hair, and various internal tissues.
The question
What role does the human tri-peptide GHK and its copper complex GHK-Cu play in tissue remodeling?
What they tested
The human tri-peptide GHK and its copper complex GHK-Cu activate various processes involved in tissue remodeling, including cell chemoattraction, anti-inflammatory actions, protein synthesis, and cell proliferation.
How they did it
This abstract reviews existing literature on the human peptide GHK and its copper complex GHK-Cu, summarizing their known biological activities related to tissue remodeling.
What they found
GHK and GHK-Cu activate several remodeling-related processes: chemoattraction of repair cells, anti-inflammatory actions (e.g., suppressing free radicals, increasing superoxide dismutase), increased protein synthesis (e.g., collagen, elastin), and increased proliferation of fibroblasts and keratinocytes, nerve outgrowth, angiogenesis, and hair follicle size. GHK-Cu has been shown to stimulate wound healing in various models and in humans. Controlled studies on aged skin demonstrated that GHK-Cu tightens skin, improves elasticity and firmness, reduces fine lines, wrinkles, photodamage, and hyperpigmentation. Additionally, GHK-Cu improves hair transplant success, protects hepatic tissue, blocks stomach ulcer development, and heals intestinal ulcers and bone tissue.
What it means
The human tri-peptide GHK and its copper complex GHK-Cu are involved in a wide array of biochemical processes that regulate tissue remodeling, demonstrating beneficial effects in wound healing, skin rejuvenation, and protection/healing of various tissues.
Limitations
The abstract does not present new experimental data but rather summarizes existing findings, without providing specific details on study designs, sample sizes, or quantitative outcomes for many of the mentioned effects.
