What was studied?
Researchers implanted mesh wound chambers in rats and compared saline with GHK-Cu exposure. Collected material was analyzed for proteins, collagen, DNA, glycosaminoglycans and selected messenger RNAs.
What did the researchers report?
The exposed chambers showed greater accumulation of several matrix components. Collagen-related signals and some collagen messenger RNAs increased, while the measured TGF-beta messenger RNA did not show the same response.
What are the limits?
An implanted wound chamber measures a controlled local tissue response, not cosmetic improvement or clinical healing in people. More matrix accumulation is not a complete measure of useful tissue repair. The results do not establish the properties of any current supply batch.
