Light microscope images: A 3D + TQ + OM, B 3D + TQ − OM, C 3D − TQ + OM, and D 3D − TQ − OM groups. Generally, cells in the alginate were scattered non-uniformly. Also, any cell morphological changes were observed between the groups (arrowhead: cell, yellow arrow: hydroxyapatite, green arrow: alginate)
