Expression of genes involved in BMP signaling in articular cartilage.

<p>Relative gene expression (mean ± SEM) of a subset of BMP agonists (top row), BMP functional antagonists (second row), BMP receptors (third row) and downstream signaling modulators (bottom row) in superficial zone (S), middle zone (M) and deep zone (D) of 1-wk old mouse tibial growth plate, measured by a multiplex solution hybridization assay (nCounter). A full list of BMP-related gene and expression values were shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0176752#pone.0176752.s001" target="_blank">S1 Table</a>.
