Figure 2.

Separated graph bar showing the grouped data of mean and SD of the optical density values (Y-axis) of the cell not exposed to materials (control), and exposed to the different grafts (B, D, G, E, and BIOS) at the different timings (T0, T1, T2, and T3). * indicates the two-way ANOVA considering the variation in the OD to assess any difference absorbance differences in the considered materials between the group exposed to the experimental materials and the negative control at the different times of seeding (T0) and the T1, T2, and T3 follow-up resulted statistically significant.
