Abstract:
OBJECTIVE: To expound the research status of the seed cells in tissue-engineered articular cartilage, and explore the resource, in vitro amplification and gene modification, so as to propose the application prospect in future.DATA SOURCES: A computer-based online search of PubMed was undertaken to identify the articles about the seed cells in tissue-engineered articular cartilage published in English between January 1994 and April 2006 with the key words of "cartilage, joint, tissue engineering, stem cell, cell culture, gene modification". Other articles were searched from Tsinghua Tongfang and Vip database according to the journal and article titles.STUDY SELECTION: The data were selected firstly to choose those about the seed cells in tissue-engineered articular cartilage and eliminate those not accorded with the requirements. The full-texts of left articles were searched manually.DATA EXTRACTION: Totally 89 articles were collected, of which 34 were included and 55 were excluded.DATA SYNTHESIS: Cells for the construction of artificial cartilage tissues include autologous or homologous chondrocytes, periost and perichondrium cells, mesenchymal stem cells and embryonic stem cells, all of which could be cultured and amplified by specific culturing system in vitro, they also could be genic modified under certain condition with different strategies and methods to repair articular cartilage defects.CONCLUSION: Seed cells with their particular characteristics play an important role in the repair of articular cartilage defects with tissue engineering technique.
