Abstract:

BACKGROUND: Simple medication therapy can not promote the healing of articular cartilage defects effectively; the insufficient sources of autogenous cartilage also limited cartilage transplantation. 
OBJECTIVE: The types of articular cartilage injury and local micro-environment changes were analyzed to summarize the progress of tissue engineered seed cell transplantation and cell transplantation therapy for repairing articular cartilage injury.
METHODS: The databases of PubMed database (http://www.ncbi.nlm.nih.gov/sites/entrez/) and CNKI (http://www.cnki.net/) were retrieved with the key words of “Tissue engineering, cell transplantation, articular cartilage defects”, and the literature was limited to English and Chinese languages. Studies concerning articular cartilage injury or was closely related to tissue engineered seed cells transplantation were included. Repetitive studies were excluded. Survival and migration of seed cells, as well as the recovery of joint function and adverse reactions were served as evaluation index.
RESULTS AND CONCLUSION: A total of 201 literatures were seized by computers, according to the inclusion criteria, papers concerning tissue engineering cells for repairing articular cartilage injury were analyzed. Clinically, articular cartilage damage was commonly resulted by traumatic arthritis, which is difficult to repair due to the poor self-repair capacity of articular cartilage. The emergence of tissue engineered cell transplantation brought new hope for articular cartilage injury healing. Cell transplantation has obtained good effects in articular cartilage repair, but the technology is still room for improvement. How to technically improve the tissue-engineered 3 elements, namely, cells, scaffold materials, and biological activity factors were the research focuses. Autologous cartilage regeneration was the theoretical support for articular cartilage defects repairing, which needs to optimize its regeneration and to maintain a more stable chondrocyte phenotype in further research. The tissue-engineered cells had received good effects in repairing articular cartilage injury, and it is expected to be a new clinical treatment for articular cartilage injury with the in-depth study of tissue engineering.
