Physical and mechanical properties of the scaffold; A the degradation rate of scaffolds. In general, scaffolds with alginate with or without thymoquinone (TQ) had less corrosion than the control group, B hydration rate of scaffolds. The amount of water absorption was similar in all the groups, C mechanical strength of the scaffolds by the diametral method. In general, the use of alginate increased the mechanical strength of the scaffolds compared to the control group. ^•Significantly different between control and alginate-TQ groups and *significantly different between control and alginate + TQ groups in chart A. *Significantly different from the controls in chart C. (*P < 0.05, **P < 0.01, ***P < 0.001), (^•P < 0.05, ^••P < 0.01, ^•••P < 0.001)
