That single fractionation study is the proof point researchers still cite more than fifty years later as the origin of the entire copper-peptide research field: a compound identified almost by accident in a liver-aging comparison went on to become one of the most studied metallopeptides in dermal and regenerative research

Local GHK-Cu exposure in a rat wound-chamber model

The expressions of -catenin, p-GSK3, and cyclin D1 were higher in hDP cells treated with NTAPP, by 2.4-fold, 1.5-fold, and 2-fold, respectively, at an output voltage of 4.2 kV as compared to control groups (Fig
