Cell proliferative effect of FGF18 on rBMSCs at 5 days.

<p>Cells were seeded at a density of 2.5×10³ cells/well on plates coated with FGF18 and incubated overnight at 4°C. Formazan absorbance was used as a measure of cell proliferation. Cell proliferation activity was expressed as cell numbers (3×103 cells/well) by MTS assay and represent the mean±SD. ^a–cDifferent letters show statistically significance difference among groups (<i>p</i><0.001).
