Figure 13

Cell viability after 3, 5, and 7 days of culture on composite scaffold of GCB 30 at 30/40/30 weight ratio as determined by MTT assay compared with glass substrate (positive control; paired with each material) on days 3 and 7. The control values were normalized to 100%. , compared with the corresponding control group (mean ± SE).
