Effects of bovine CP compounds on the proliferation of MC3T3-E1 cells.

<p>The proliferation of MC3T3-E1 cells was measured by MTT assays after treatment with CP at 0.1–6 mg/mL (A) or 0.3 and 3 mg/mL (B) for 3–7 days. Data are expressed as means ± standard deviation (<i>n</i> = 6). *<i>p</i><0.05, **<i>p</i><0.01, Significant difference from CN. CP: bovine collagen peptides compounds; CN: control.
