Figure 5From: Mechanical strain promotes osteoblast ECM formation and improves its osteoinductive potential Runx2 and OCN mRNA levels of MC3T3-E1 cells re-seeded on ECMs. The ECM produced by the mechanically strained cells increased mRNA level of Runx2 after 5, 7, and 10 days of culture and increased OCN mRNA level after 7 and 10 days of culture. *P < 0.05, ** P < 0.01, between the indicated groups. Quantitative results are the means ± standard error of 7 experiments.Back to article page
