FSS promotes BMP2 synthesis and secretion.

<p>(A) FSS up-regulated transcriptional level of <i>BMP2</i> gene. Relative level of <i>BMP2</i> was determined by qRT-PCR at a series of time points after FSS load. (B) Extracellular level of BMP2 protein was examined using ELISA. (Data were shown as mean ± SD. <i>n</i> = 3. *, <i>P</i><0.05; **, <i>P</i><0.01; ***, <i>P</i><0.001.)</p>
