Effects of PEMF exposure on in vitro osteogenesis-related gene expressions for osteoblasts seeded in pTi via semi-quantitative RT-PCR analyses, including Runx2, Osx, COL-1, Wnt1, Lrp6 and β-catenin.
Values are all expressed as mean ± S.D. (n = 8 ~ 11) and the relative expression level of each gene was normalized to β-Actin. *Significant difference from the Control group with P < 0.05.
