Effects of varying concentrations of agents on fibroblast cell proliferation. DHF were treated with various concentrations of (A) H₂O₂; (B) Cr; (C) NAM, water (1%) vehicle, or no treatment (sham; NT) and MTT assays performed at days 1, 2, or 3 to assess cellular viability. The data are mean ± SE of triplicate experiments. * Statistically significant (p < 0.05) decreased relative cell proliferation was found on days 2 and 3 of 800 μM and 1 mM H₂O₂ treatment, as well as 20 mM NAM at days 2 and 3.
