demonstrated dose-dependent proliferation effects on cultured human dermal papilla cells exposed to GHK-Cu at physiologically relevant concentrations.3 Subsequent work has confirmed that this effect translates into upregulation of genes associated with anagen-phase activity including VEGF, FGF-2, and IGF-1, the three growth factors most directly implicated in hair-cycle regulation
During the initial period, leukocyte-derived MMP-9 and brain-derived MMP-2 are involved, and later, MMP-3 and MMP-9, angiogenesis, and vasogenic edema may occur, which can destroy NVUs and exacerbate the destruction of the BBB [120, 121]
