Abstract

Introduction: Follicles are the basic functional units of the ovary. It is characterized by the growth and development of ovarian follicles, proliferation and differentiation of granulosa cells. Oocytes are found in the graaf follicle surrounded by cumulus granulosa cells. Our aim in this study is to isolate the cumulus granulosa cells, which form the microenvironment of the oocyte, more easily and quickly. Materials and Methods: Two female patients aged 25-30 years, with ten or more follicles and male factor infertility were included in the study. The cumulus granulosa-oocyte complexes obtained after OPU (oocyte pick-up) were denuded to separate them from each other. Then, the cumulus granulosa cells were seeded into culture dishes coated with Type I collagen and primary cell culture was established. Results: Cumulus granulosa cells inoculated in flask culture dishes proliferated and became confluent on the 14th day. In the count made under the microscope, it was observed that 4x105 and 5x 10 5 cells were grown in the culture dishes, respectively. Conclusion: The ability to culture cumulus granulosa cells more easily thanks to the isolation methods developed can accelerate the studies on obtaining quality oocytes and embryos.

Özet

Amaç: Bu araştırmada 30 Mayıs 2021 tarihine kadar COVID-19 aşıları ile ilgili PubMed’de yayınlanmış randomize kontrollü çalışmaların tanımlayıcı özelliklerinin incelenmesi amaçlanmıştır. Gereç ve Yöntemler: PubMed veri taban ında “vaccine” ve “COVID 19” anahtar kelimeleri taranarak ulaşılan 73 makale araştırmacılar tarafından incelenmiş, COVID 19 a şıları ile ilgili olan 33 randomize kontrollü çalışma (RKÇ) ara ştırmaya dahil edilmiştir. Amaç: Foliküller, ovaryumun temel fonksiyonel birimleridir. Overyan foliküllerin büyümesi ve gelişmesi, granüloza hücrelerinin çoğalması ve farklılaşması ile karakterizedir. Oositler graaf folikül içerisinde kumulus granulosa hücreleriyle çevrili olarak bulunur. Bizim bu çal ışmadaki amacımız oositin mikroçevresini oluşturan kumulus granüloza hücrelerini daha kolay ve hızlı bir şekilde izole etmektir. Gereç ve Yöntem: Çalışmaya 25-30 yaş aralığında, folikül sayısı on ve üzerinde olan ve infertilite nedeni erkek fa ktör olan iki kadın hasta al ındı. Oosit toplama i şleminden (OPU) sonra elde edilen kumulus granüloza-oosit komplekslerine birbirlerinden ayrılmaları için denüdasyon i şlemi uygulandı. Daha sonra kumulus granüloza hücreleri Tip I kollajen ile kaplı kültür kaplarına ekilerek primer hücre kültürü oluşturuldu. Bulgular: Flask kültür kaplarına ekilen kumulus granüloza hücreleri prolifere olarak 14. günde konflue oldular. Mikroskop altında yap ılan sayımda kültür kaplarında s ırasıyla 4x105 ve 5x105 hücrenin ürediği gözlemlendi. Sonuç: Kumulus granüloza hücrelerinin geliştirilen izolasyon yöntemleri sayesinde daha kolay bir şekilde kültüre edilebilmeleri kaliteli oosit ve embriyo elde edilmesi yönündeki çalışmalara ivme kazandırabilir.
