Abstract:

BACKGROUND: Alveolar bone absorption and defect caused by various physiological or pathological factors is a common problem in oral clinical medicine, but the most commonly used methods to repair alveolar bone defects cannot fully meet clinical needs. The emergence of bone tissue engineering for bone defect repair has become a research hotspot.   
OBJECTIVE: To review the source and application of adipose stem cells, the types and characteristics of biological scaffolds, the effect of biological scaffold on seed cells and the application of adipose stem cells composite scaffolds in animal experiment research.
METHODS: A computer-based search of CNKI and PubMed (1995-01/2013-04) was performed to retrieve the related articles about adipose stem cells, biological scaffold and bone repair. The keywords were “adipose stem cells, differentiation, proliferation and osteogenesis, biological scaffold, alveolar bone, bone tissue engineering” in Chinese and English, respectively. Articles published recently or in authorized journals were preferred. There were163 articles after the initial survey. Then, 40 articles were included in result analysis.
RESULTS AND CONCLUSION: Adipose stem cells have a differentiating potential similar to bone marrow stromal stem cells. Adipose stem cells have been widely drawn by variety of sources, easy collection, easy to cultivate and low aging, good osteogenetic differentiation and low risk. Especially, adipose stem cells and biological scaffolds used in bone repair show better osteogenesis effect. With the development of science, problems related to alveolar bone defect repair can be solved. Adipose stem cells and biological scaffold for construction of tissue-engineered bone will be realized in the true sense of the alveolar bone regeneration, with good prospects for development.
