From: Mechanical strain promotes osteoblast ECM formation and improves its osteoinductive potential
Calcium, hydroxyproline, and BMPs levels in the ECM coated on dishes. The mechanical strain increased the contents of calcium and hydroxyproline of the ECM at the indicated times (A), the mechanical stimulus for 7 days enhanced the relative protein expression levels of BMP-2 and BMP-4 (B). *P < 0.05, ** P < 0.01, between indicated groups. Quantitative results are the means ± standard error of 6 experiments.
