To examine how the noncollagenous matrix proteins osteocalcin and osteopontin interact to influence bone morphology and mechanical performance.
Evaluated bone morphology, tissue mineral density, and mechanical properties across experimental groups lacking osteocalcin (OC), osteopontin (OPN), or both proteins.
Assessed mechanical competence using measures of maximum bending load, structural stiffness, and overall strength.
Maximum bending load differed significantly among groups (P = 0.024), accompanied by significant morphological differences between groups (P < 0.05).
Tissue mineral density as well as direct measures of stiffness and strength did not differ significantly between groups (P > 0.1).

Implication

Comparative study reveals structural adaptation maintains bone strength after osteocalcin and osteopontin loss, indicating synergistic regulation of bone morphology.
