Abstract (original English)

As propose of organ repair stem cell therapy technology, articular cartilage cannot be repaired by itself has become one of the research hotspots, repair of articular cartilage with mesenchymal stem cells has shown obvious advantages for the treatment. The scholars have made a preliminary study on the role of mesenchymal stem cells from different sources in the repair of knee articular cartilage, and with the combination of transplantation and cartilage tissue engineering, these technologies improved the human cartilage repair effect of bone marrow, adipose, synovium, cord blood derived stem cells, which achieved good clinical curative effect. Due to the different sources, the dominant and recessive factors, each stem cell will have certain advantages and disadvantages. At present, the clinical research is still in the experimental stage, there is no definite conclusion on which kind of stem cell or technology is more suitable for human cartilage repair. This requires the validation of large-scale or combining with new processing technology clinical trials and the long-term clinical effect, it also provides for the basis for further clinical research.

Evidence level
