Osteostatin-loaded onto mesoporous ceramics improves the early phase of bone regeneration in a rabbit osteopenia model.

Parathyroid hormone-related protein (PTHrP) is an important modulator of bone formation. Recently, we reported that PTHrP (107-111) (osteostatin) coating onto mesoporous ceramics confers osteogenic activity to these materials. Bone repair is dramatically compromised in osteopenia/osteoporosis.

The osteoinductive properties of mesoporous silicate coated with osteostatin in a rabbit femur cavity defect model.

Parathyroid hormone-related protein (PTHrP) is an important regulator of bone formation and remodeling. Our recent findings demonstrate that PTHrP (107-111) (osteostatin) loaded onto silica-based ordered mesoporous SBA15 materials exhibit osteogenic features in osteoblastic cell cultures. We aimed here to elucidate whether these peptide-coated materials might be suitable for promoting bone repair following a cavitary defect in the rabbit femur.
