Research progress of ovarian tissue vitrification

Vitrification provides a rapid cooling to induce glass-like solidification inside cells and protect cell membrane and cytoskeleton system free of injury by ice crystals. The main factors that can influence the effect of vitrification are the size of ovarian tissue,the kind of cryoprotectants,the method of permeation,carrier system and so on.Ovarian tissue structure is very complex,and there is no uniform standardized protocol of vitrification yet. This paper presents also the current problems of ovarian tissue vitrification.
