Novel injectable and self-setting composite materials for bone defect repair

Injectable Degradable Composite Materials for Bone Repair and Drug Delivery

Injectable gel graft for bone defect repair.

AIM To examine the performance of an injectable gel graft made of transglutaminase (Tg)-crosslinked gelatin gel with BMP-2 (BMP-2-Tg-Gel) for bone defect repair in animal models. MATERIALS & METHODS BMP-2 mixed with gelatin gel was crosslinked using Tg. The release of tethered BMP-2 through autocrine and paracrine pathways was demonstrated by using C2C12 and NIH 3T3 cells, respectively. BMP-2...

A Novel Porous Gelatin Composite Containing Naringin for Bone Repair

As Gu-Sui-Bu (GSB) is a commonly used Chinese medical herb for therapeutic treatment of bone-related diseases, naringin is its main active component. This study elucidates how various concentrations of naringin solution affect the activities of bone cells, based on colorimetric, alkaline phosphatase activity, nodule formation, and tartrate-resistant acid phosphatase activity assays to determine...

Evaluation of the Repair of Bone Defect after Bone Marrow Stromal Cell Transplantation in Rat

Background & Objective: Bone marrow stromal cells (BMSCs) are multipotent stem cells that can proliferate and differentiate into osteogenic cells . T his study aimed to investigate the effects of BMSC transplantation for the repair of bone defects in the rat.   Materials & Methods : Twenty-eight male adult rats were divided into 4 groups. Group 1 ( control group) received no treatment after the...

Development of an injectable composite for bone regeneration

With the development of minimally invasive surgical techniques, there is a growing interest in the research and development of injectable biomaterials especially for orthopedic applications. In a view to enhance the overall surgery benefits for the patient, the BIOSINJECT project aims at preparing a new generation of mineral-organic composites for bone regeneration exhibiting bioactivity, thera...
