An investigation of the specificity of induced anti-pig antibodies in baboons.

abstract：BACKGROUND:Autograft (AG) is the gold standard bone graft due to biocompatibility, osteoconductivity, osteogenicity, and osteoinductivity. Alternatives include allografts and xenografts (XG). METHODS:We investigated the osseointegration and biocompatibility of a decellularized porcine XG within a critical defect anima...
