Abstract:
BACKGROUND:The traditional treatment methods for osteoporosis accompanied by bone defects, such as autogenous bone graft, al ograft, biomaterial implants, have significant limitations. The regenerative medicine approach using adipose-derived stem cells as seed cells offers a new way for the repair of bone defects fol owing osteoporosis. OBJECTIVE:To review the pathogenesis of osteoporosis and its impacts on the repair of bone defects, the signal pathway regulation of osteogenic differentiation of adipose-derived stem cells, and the feasibility of adipose-derived stem cells for repairing osteoporotic bone defects. METHODS:A computer-based online search of CNKI database and PubMed database was performed to retrieve the relevant articles published from January 1998 to September 2014 with the key words of“adipose-derived stem cells, osteoporosis, bone defect, osteogenic differentiation, bone regeneration”in Chinese and English, respectively. Final y 77 articles were included for review after deleting unrelated and repetitive ones. RESULTS AND CONCLUSION:In recent years, adipose-derived stem cells have been widely used in regenerative medicine research. With the development of relevant disciplines such as regenerative medicine, tissue engineering, molecular biology, and material science, in-depth studies on regulatory mechanisms of osteogenic differentiation of adipose-derived stem cells have been developed. Adipose-derived stem cells combined with biological scaffolds for construction of tissue-engineered bones provides a new way to repair osteoporotic bone defects.
