a Tartrate-resistant acid phosphatase (TRAP) staining images of mouse distal femora. Bars: 50 μm. GNX gonadectomy, MSCT mesenchymal stem cell transplantation in GNX mice. b, c Corresponding parameters of TRAP staining. N.Oc/BS number of osteoclasts over bone surface, Oc.S/BS osteoclast surface over bone surface. df Serological markers of osteoclastogenesis. RANKL receptor activator of nuclear factor κB ligand, OPG osteoprotegerin. g The serological marker of bone resorption, CTX-1 cross-linked C-telopeptide of type 1 collagen. n = 5 per group. The data represent the means ± SD. *P < 0.05; NS, not significant (P > 0.05)
