Abstract

The aim of this study was to investigate the effects of fetal calf serum and cumulus cells on in vitro fertilization of rabbit oviductal oocytes. In this study, 24 female and 2 male New Zealand White rabbits were used as donors of gametes. Following the induction of superstimulation with PMSG, and ovulation with hCG, cumulus oocyte complexes (COC) were collected by flushing the oviducts with PBS supplemented with BSA. Some of the oocytes were used in fertilization with cumulus cells others were used without cumulus cells. Gametes were cultured for 5 hours in mDM for fertilization. Then, presumptive zygotes were placed in one of the following two media for 18 to 21 hours to determines the effect of serum supplementation and cumulus cells on cleavage rates: Ham's F-10 alone, supplemented with 20% FCS. Fertilization was assesed by detection of oocytes cleavage rates. Cleavage rate were 72.2 % oocytes with cumulus cells for Ham's F-10 supplemented with 20% FCS, 66.7 % oocytes with cumulus cells for Ham's F-10 alone and 68.6 % oocytes without cumulus cells for Ham's F-10 supplemented with 20% FCS, 55.3 % oocytes without cumulus cells for Ham's F-10 alone (P>0,05). Although differences were not statistically significant, numerical differences supported the use of serum and cumulus cells in rabbit zygote culture media.

Özet

Bu çalışma tavşan oviduktal oositlerinin in vitro fertilizasyonunda kümülüs hücreleri ile fötal buzağı serumunun etkilerinin araştırılması amacıyla yapılmıştır. Çalışmada 24 Yeni Zelanda- Beyaz dişi, 2 Yeni Zelanda Beyaz erkek tavşan kullanılmıştır. PMSG ile süperfollikülasyon ve HCG ile süperovulasyon oluşturulduktan sonra BSA içeren PBS ile ovidukt yıkanarak kümülüs oosit kompleksleri (COC) toplanmıştır. Oositlerin bir kısmı kümülüs hücreleriyle birlikte diğer kısmı ise kümülüs hücrelerinden ayrılarak fertilizasyona alınmıştır. Gametler fertilizasyon için mDM'de 5 saat inkübe edilmiştir. Kümülüs hücreleri ve Fötal Buzağı Serumun, bölünme oranlan üzerine etkisinin belirlenmesi amacıyla zigotlar % 20 FCS ilave edilmiş olan Ham's F-10 ile FCS ilave edilmemiş Ham's F-10. mediumuna alınarak 18-21 saat kültüre edilmiştir. Fertilizasyonun değerlendirilmesi oositlerin bölünme oranları saptanarak yapılmıştır. Bölünme oranları kumuluslu oositlerde % 20 FCS bulunduran Ham's F-10 mediumunda % 72.2, FCS bulundurmayan Ham's F-10 mediumunda ise % 66.7 bulunmuştur. Kumulussuz oositlerde ise bölünme oranlan % 20 FCS bulunduran Ham's F-10 mediumunda % 68.6, FCS bulundurmayan Ham's F-10 mediumunda ise % 55.3 olarak bulunmuştur (P>0,05). Sonuçların istatistiksel açıdan önemli olmamasına karşın tavşan zigotu kültür mediumunda serum ve kümülüs hücrelerinin kullanımının olumlu etkileri saptanmıştır.
