Research Progress of Tissue Engineered Bone in Repairing Bone Defect

A novel tissue-engineered bone in repairing femoral head defect and necrosis.

OBJECTIVE To evaluate the therapeutic effects of AACB/BMP/bFGF, a novel tissue-engineered bone, in repairing femoral head defect and necrosis in dog models. METHODS Dog models of avascular necrosis of femoral head (ANFH) were established by liquid nitrogen freezing method. Group A was untreated; Groups B, C, and D were implanted with AACB, AACB/BMP, and AACB/BMP/bFGF complex, respectively; Gr...

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...

Skeletal homeostasis in tissue-engineered bone.

Tissue-engineering strategies to stimulate bone regeneration may offer an alternative approach to conventional orthopaedic and maxillofacial surgical therapies. Over the last decade, significant advances have been accomplished in developing biomimetic matrices, growth factors, cell transplantation and gene delivery therapeutics to support new bone growth. However, it is not known if tissue-engi...

Functional integration of tissue-engineered bone constructs.

Engraftment of Prevascularized, Tissue Engineered Constructs in a Novel Rabbit Segmental Bone Defect Model

The gold standard treatment of large segmental bone defects is autologous bone transfer, which suffers from low availability and additional morbidity. Tissue engineered bone able to engraft orthotopically and a suitable animal model for pre-clinical testing are direly needed. This study aimed to evaluate engraftment of tissue-engineered bone with different prevascularization strategies in a nov...
