Real-time PCR results. (a) Collagen type I (COL1) and (b) alkaline phosphatase (ALP) genes expression of 3D bone tissue models cultured for 14 days under static culture (control), bi-directional perfusion, or bi-directional perfusion combined with PEMF stimulation (p < 0.05 with respect to control indicated by #, p < 0.05 with respect to bi-directional perfusion indicated by §). Bars represent means and standard deviations, replicates n = 3.
