Abstract:

BACKGROUND: Cryopreservation can preserve the activity and function of the in vitro tissues in the greatest degree, which create the enormous push and facilitation effect in medical research and clinical treatment. But in the composite tissue cryopreservation, there also has many problems in the application of cryoprotectant waiting for solve.
OBJECTIVE: To review the domestic and foreign research progress in the application of cryoprotectant in tissue cryopreservation
METHODS: The PubMed database, Chinese journal full-text database and Wanfang database were searched by the first author for the literatures published from January 2003 to December 2012. The key words were “cryopreservation, cryoprotectant, composite tissues, vitrification, transplantation” in Chinese and English. Totally 143 relevant literatures were collected, and 56 of them were in accordance with the inclusion criteria.
RESULTS AND CONCLUSION: Since the beginning of the last century, domestic and overseas experts have made great efforts on the research of tissue cryopreservation through a lot of fundamental experimental researches of animal cells and tissues, and variety of cryopreservation techniques and various cryoprotectants were applied and obtained a certain achievements, it found that the application of cryoprotectant played a crucial role in tissue cryopreservation. Cryopreservation is widely applied in some domains, such as tissue engineering, reproductive medicine and transplantation field. But at present, the application of cryoprotectant in composite tissue cryopreservation is still under studying in laboratory. The types and concentrations of cryoprotectant, as well as the addition and elution process can directly determine the ultimate success of cryopreservation.

Key words: organ transplantation, organ transplantation review, cryopreservation, composite tissue, vitrification, cryoprotectant agent, rewarming, cooling, limb replantation, allograft, permeability injury, research progress
