Biomaterials are increasingly being evolved to actively adapt to the desired microenvironments so as to introduce tissue integration, reconstruct stability, promote regeneration, and avoid immune rejection. The complexity of its mechanisms poses great challenge to current biomimetic synthetic materials. Although still at initial stage, harnessing cells, tissues, or even entire body to synthesize bioadaptive materials is introducing a promising future.
Bone protein extract is regarded as the new generation of demineralized bone matrix. The aim of this paper is to describe and characterize the properties of demineralized bone matrix and its new generation product in addition to its application in animal and human studies. Bone protein extract has features of osteoconductivity, osteoinductivity and osteogenicity, which originate from its unique and precise processing. It has exhibited powerful bone formation capacity both in animal experiments and in clinical trials by providing an optimal microenvironment for osteogenesis. Furthermore, not only does it have excellent bio- compatibility, it also has good compatibility with other implant materials, helping it bridge the host and implanted materials. Bone protein extract could be a promising alternative for demineralized bone matrix as a bone graft substitute.
