Abstract:

BACKGROUND: Because of deficiency of nerves and blood vessels of articular cartilage, its nutrition is mainly derived from the synovial fluid or synovial vascular osmosis. Limited in their ability to repair itself, so how to repair articular cartilage damage better become medical problems to be solved. 

OBJECTIVE: To review to the literatures on the repair of cartilage damage method and allogeneic cartilage in vitro preservation method in recent years, and to find the optimal preservation conditions and the culture medium composition that suitable for in vitro preservation of allogeneic cartilage tissues, thus enhancing the effect of allogenic cartilage in vitro preservation.
METHODS: A computer-based online search was performed in the PubMed database and the CNKI database to search papers on the in vitro liquid preservation of allogeneic cartilage graft published from January 1990 to February 2013. The key words were “osteochondral allograft, tissue culture, chondrocyte survival rate, in vitro” in English and “articular cartilage; allogeneic transplantation; liquid preservation” in Chinese. The articles published earlier and repetitive researches were excluded.
RESULTS AND CONCLUSION: At present, there are two methods for the preservation of allogenic osteochondral grafts. After cryopreservation, the survival rate of chondrocytes is decreased significantly which can affect the transplantation effect, therefore there is less clinical application. Liquid preservation method can enhance the survival rate of cells, maintain the organization activity, but the preservation time is short that cannot be widely used. Scholars have further improved the environment of liquid preservation and composition of liquid culture medium, extended the in vitro preservation time of cartilage tissue, and improved the effectiveness of cartilage tissue preservation.
