Van Gieson’s picro-fuchsin staining of the samples for histological analysis of new bone formation and β-TCP residue at 24 weeks post-operatively. (A) From top to bottom: BMSC-BM/β-TCP, BM/β-TCP, β-TCP and blank group (original magnification 10× and 40×). New bone appears red, and β-TCP appears black. (B, C) There were significant differences between the BMSC-BM/β-TCP group and control groups in the new bone area and β-TCP residue (*p < 0.05, **p < 0.01).
