An implant for treating a bone defect wherein the implant comprises osteoconductive supporting bodies and an insertion aid. The insertion aid is designed for insertion of the osteoconductive supporting bodies into a bone defect and for holding together the osteoconductive supporting bodies. Also disclosed is a kit comprised of an implant for treating a bone defect.

An inducer is directed to the induction of in situ regeneration in regenerative medicine. The inducer including an extracellular matrix and/or a bone morphogenetic protein, can induce the regeneration of bone and soft tissues surrounding the bone such as muscle, blood vessel and skin at the residual tissues where trauma occurs. The amount of regenerated tissue is associated with the dose of the implanted inducer.

The present invention provides porous biomimetic scaffolds and methods for making the same. The scaffolds have graded pore sizes for enhanced cell penetration. The scaffolds are useful for wound regeneration by facilitating cell penetration into the scaffold interior and due to their inherent immunomodulatory effects. The scaffolds have tissue modeling specification by mimicking the inherent stratified structure of certain tissues.

Provided is a cardiovascular implant based on in-situ regulation of immune response and a method for making the same, belonging to the technical field of biomedicine. The cardiovascular implant includes a cardiovascular implant body and H4000-CD25/dcas9 sustained-release nanoparticles modified on the cardiovascular implant body; the H4000-CD25/dcas9 sustained-release nanoparticles include an H4000 plasmid nanocarrier (Engreen), an anti-CD25 antibody, and a dcas9 plasmid sequence; a method for preparing the cardiovascular implant includes: constructing a cardiovascular implant body, preparing an H4000-CD25 nanotransfection vector, preparing H4000-CD25/dcas9 sustained-release nanoparticles, and conjugating the H4000-CD25/dcas9 sustained-release nanoparticles on the cardiovascular implant body. The present disclosure aims to construct a cardiovascular implant modified with the H4000-CD25/dcas9 sustained-release nanoparticles, which may induce nerve fiber ingrowth into engineered blood vessels; with the regulation ability of Treg cells on immune response, antithrombotic function of the cardiovascular implant is improved and in-situ regeneration of the cardiovascular implant is promoted.

A method and system for making a bone plug using cortical bone material. A patient jaw having insufficient bone at a surgical site may be scanned to provide a 3D image which may be used to design a virtual bone plug and to fabricate the bone plug for placement within the patient. The bone plug may be formed from cortical bone that can be reconstituted and demineralized or demineralized and milled to shape.

The invention provides a thermosensitive peptide hydrogel, which comprises water, a polyether/polyol polymer and a peptide molecule. The peptide molecule has a structure represented by the following chemical formula (1). Chemical Structure (1): ##STR00001##
