Abstract

Human gametes and embryos at different development stage show variable physiological necessities and requirements in order to survive in in-vivo conditions. Therefore, all laboratory procedures can cause damage to human gametes and embryos. Cryopreservation procedures are such unphysiological circumstances mainly due to severe temperature and osmotic alterations. Since the early of 1980s, two common methods of cryopreservation were been used. Both of these methods are finally depending on the freezing and solidification of cell or tissue. Recently, the latter one that known as vitrification has claimed to be the future of cryopreservation because of increased survival and success rates. However, this method is a non-equilibrium technique of cryopreservation that shows critical requirements of much higher concentration of permeable cryoprotectants and rate of cooling. Thus, it has defined to be a more vigorous in mean of all possible cell damage except the formation of intracellular crystals that is totally prevented by vitrification. Nevertheless, there is no adequate cumulative data on the outcomes of vitrification preformed at different stages of human embryos. The aim of this review is to assess the possible differences of outcomes of vitrification those performed at different stage of human embryos.

Özet

İnsan gamet ve embryoları in vivo ortamda degişik gelişimsel hücre evrelerinde iken canlı kalmak için değişik fizyolojik ihtiyaçlar göstermektedirler. In vitro ortam olan tüm laboratuar prosedüreleri ise insan gamet ve embryolarının hasarlanabilceği ortamlardır. Krioprezervasyon uygulamaları fizyoyojik olmayan ve ciddi ısı ile osmotik değişikliklere ihtiyaç duyan güncel laboratuar uygulamalarıdır. 1980’lerin başlarından itibaren kullanılan düşük oranlı dondurma ile vitrifikasyon olarak adlandırılan iki ana krioprezervasyon methodu bulunmaktadır. Her iki methot temelde hücre veya dokunun donma yada katılaşması esasına dayanmaktadır. Yakın zamanda tanımlanan vitrifikasyon artmış cözme sonrası yaşam ve başarı oranları ile insan gamet ve embiryolarının krioprezervasyonunda gelecekte tercih edilmesi gereken method olarak nitelendirilmiştir. Fakat, bu method bir non-equilibriyum teknik olup daha yüksek permeable kryoprotektant konsantrasyonu ile daha yüksek soğutma oranına ihtiyaç duymaktadır. Bu nedenler ile vitrifikasyon ile krioprezervasyon esnasında intrasellüler buz kristallerinin oluşmasının önlenebilmesi haricinde hücre hasarının daha yüksek olacağı düşünülmüştür. Bu review ile insan gamet ve embriyolarının değişik hücre evrelerinde yapılan vitrifikasyonun sonuçları ve güncel biligiler özetlenmiştir.
