The main published study is a 2007 laboratory paper from the Department of Dermatology at Seoul National University. The authors built on earlier work describing tripeptide-copper complexes as growth factors for several differentiated cell types, including dermal fibroblasts. They tested AHK-Cu on human hair follicles kept alive outside the body (ex vivo) and on cultured dermal papilla cells, the specialized fibroblasts at the base of the follicle that are involved in follicle growth.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eHair follicle elongation ex vivo and dermal papilla cell proliferation were greater with AHK-Cu than without it.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eMarkers of programmed cell death shifted in dermal papilla cells: the Bcl-2 to Bax ratio rose, and cleaved caspase-3 and PARP fell.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n\u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eThe fall in the number of apoptotic cells itself was not statistically significant.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eWhat do these laboratory findings mean?\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThey describe a mechanism under investigation in isolated tissue and cells.

AHK-Cu starts with alanine, while GHK-Cu starts with glycine. GHK occurs naturally in human plasma and has a much larger body of research, reviewed by Pickart and colleagues.
