摘要: The purpose of this study was to compare each the 14 naturally occurring lanthanoid metal ions for ability stimulate pro-fibrotic responses in human dermal fibroblasts. When fibroblasts were exposed individual lanthanoids over concentration range 1–100 μM, increased proliferation observed with agents as compared control cells that already proliferating rapidly a growth factor-enriched culture medium. Dose–response differences among ions. Matrix metalloproteinase-1 (MMP-1) and tissue inhibitor levels also response exposure but type I procollagen production not. A dose–response relationship between induction MMP-1 observed. Non-lanthanoid transition (aluminum, copper, cobalt, iron, magnesium, manganese, nickel, zinc) examined same assays; there little stimulation any these metals. epidermal keratinocytes place fibroblasts, no lanthanoids. Several metals inhibited keratinocyte at higher concentrations (50–100 μM).
