title: [Progress in vitreous cryopreservation of living bioproducts].
abstract: In this brief review, some key issues related to vitreous cryopreservation of living tissues (natural or engineered), including cells, embryos, tissues, organs, and engineered tissues, are outlined. The principle of vitreous cryopreservation for the biological activity and functionality is demonstrated. The procedures of cooling/ rewarming, composition and function of optimal cryoprotectants, and their effects on bioproducts are described. Vitrification could, therefore, prove to be a useful and effective method of bioproduct cryopreservation for a long period of time, particularly for organized tissues and organs. However, the toxicity of the cryoprotective agents and the devitrification occurring during the rewarming process need additional investigations. Several key areas of research on vitrification are also addressed.
