Abstract

Implantation of demineralized diaphyseal bone matrix in subcutaneous sites induces a sequence of events resulting in the local differentiation of endochondral bone. Demineralized bovine bone matrix was dissociatively extracted in 4.0 M guanidine hydrochloride and the bone-inductive proteins were purified greater than 12,000-fold. The purification steps include affinity chromatography on heparin-Sepharose, hydroxyapatite chromatography, gel filtration, and C18 reverse-phase HPLC. Since the purified protein in conjunction with insoluble collagenous bone matrix induced new bone differentiation in vivo we have designated this component osteogenin. The osteogenic potential is specific for osteogenin and is not exhibited by previously isolated growth factors.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
