SURFACE-ACTIVE COLLAGEN BARRIER MEMBRANE TO WHICH A PEPTIDE IS BOUND

摘要

The present invention relates to a barrier membrane to which a peptide, which binds to collagen and which is capable of regenerating bone tissue, is bound. More particularly, the present invention relates to a collagen barrier membrane in which a fusion peptide consisting of a collagen-bound peptide and a functional bone-tissue-regenerating peptide is fixed to the surface of collagen. According to the present invention, the surface-active collagen barrier membrane, in which a fusion peptide is coupled to the surface of collagen, can stably bind to the body due to increased local retention, and promote the transport, proliferation, and differentiation of cells, to thereby ultimately maximize bone-tissue-regenerating capacity when implanted in the body. Therefore, the barrier membrane of the present invention is useful in the development of guided bone-regeneration technology. In addition, a fusion peptide can be applied to implants made of collagen having other shapes, and a collagen-bound peptide, which constitutes the fusion peptide, can be bound to and synthesized with a peptide having effects in regenerating other tissue, and therefore can be useful in tissue-regenerating biomaterials for other purposes, e.g. for regenerating skin.
