Abstract:
To investigate the feasibility of β-tricalcium phosphate (TCP)/gelatine scaffold combined with allogeneic adipose-derived stem cells (ASCs) to repair hole shape defect, third-passage ASCs were seeded onto composite scaffolds to prepare an ASC-β-TCP/gelatine tissue-engineered bone to pack into the rabbit cavernous bone defects of experimental groups. In animal models, the bone defect area was completely filled and difficult to recognize in the experimental group at 12 weeks post-surgery by gross observation and radiographic examination. The average bone mineral density value of them was higher than that of the control group. Because of the biocompatibility with allogenic ASCs and the osteoconductivity of β-TCP/gelatine scaffolds, β-TCP/gelatine is suitable as a plastic scaffold for the ASC-seeded tissue-engineered bone to repair cavernous defects.
