mRNA expression levels of Runx2 and OCN in BMSCs seeded on the ECMs. After 5 and 7 days of culture, the relative mRNA level was assayed using real time polymerase chain reaction, Runx2 mRNA and OCN mRNA are the highest levels in BMSCs seeded on osteoblast-ECM, * P <0.05, **P <0.01, between the indicated groups, n = 6 per group.
