Fig. 5. (a) RT-PCR results for expression of RUNX2 and SOX9 of osteodifferentiated cells (106 cells per well) on scaffolds (0.5 × 0.5 cm2). The expression of β2M was recorded as a control gene. (b) ICC results for expression of osteonectin of osteodifferentiated cells on scaffolds after 21 days. The magnification is 400.
