Fig 2. Gene expression of the indicated bone-specific markers as determined by qRT-PCR.
hBM-MSCs were seeded and cultured in osteogenic medium on TiO2 nanostructured surface with/without PEMF stimulation for 7 (A) and 28 (B) days, respectively. Statistical significance values are indicated as *** p < 0.001 and # p > 0.05.
