Brief Summary:
Commercial decalcified bone scaffolds were combined with autologous bone marrow mesenchymal stem cells to form tissue engineered bone in vitro to explore the effect of this tissue engineered bone in the clinical repair of long tubular bone defects in limbs.
Detailed Description:
Bone defects caused by trauma, tumors, and other factors, particularly weight-bearing long tubular bone defects in the limbs, pose significant harm to patients and severely impact their quality of life, remaining a major clinical challenge. Current repair methods such as autologous bone grafting, vascularized autologous bone grafting, allogeneic bone grafting, induced membrane technique, and bone transport technique face limitations including lengthy treatment cycles, high costs, restricted donor sites and bone harvest quantities, and unpredictable outcomes.
To address these challenges, the National Engineering Research Center for Tissue Engineering has developed an innovative approach through continuous research and innovation. This method utilizes autologous bone marrow mesenchymal stem cells (BMSCs) with minimal invasiveness, strong proliferation capacity, and potent osteogenic potential as seed cells for bone construction. These cells are combined with clinically approved allogeneic decalcified bone materials to create tissue-engineered bone through in vitro induction. This approach offers multiple advantages: absence of immune rejection, unrestricted material sources, sufficient cultured bone volume, and high survival rates, providing a new direction for treating long tubular bone defects in limbs.
This study aims to evaluate the clinical efficacy of tissue-engineered bone constructed with autologous BMSCs for repairing long bone defects in extremities, thereby providing evidence-based support for bone defect treatment.
