Effect of exogenous MMP-3 on cell proliferation in odontoblast-like cells.

<p>Effects of exogenous MMP-3 on odontoblast-like cells proliferation derived from iPS cells, ES cells and KN-3. Cells were incubated in serum-free medium in the absence or presence of various concentrations of MMP-3 (0, 10, 30, 50 and 100 ng/mL) for 24 h prior to cell proliferation evaluation using the BrdU-cell proliferation ELISA. Data are the mean ± SD of six independent experiments; (vs. control, *<i>P</i><0.05, **<i>P</i><0.01).
