In Vivo Small Animal Model

Osteoinductivity (In Vitro)
In Vitro assays can be used to estimate the potential osteo-inductivity of demineralized bone matrix (DBM) as a screening tool for raw materials and final product or as an alternative to animal testing. Two platforms are available: the alkaline phosphatase assay and the BMP (bone morphogenic protein, -2, -4 or-7) ELISA assays.

Osteoinductivity (In Vivo)
In Vivo assays in nude mice or rats are used to definitively prove the ability of a DBM product to induce ectopic bone formation. The study is performed by intra- or inter-muscular implantation of product followed by histopathology.

Other Custom Services
Additional customized studies that complement a tissue testing program, including biocompatibility testing and cell-based potency assays.
