Burada, kuş preovulatuar foliküllerinde yumurta sarısı, granüloza hücreleri ve teka hücrelerini ayırmak için bir protokol açıklıyoruz. Bu hassas işleme, bu katmanların üreme işlevindeki rolüne ilişkin kritik araştırmalara olanak tanıyarak, gelişmiş tarımsal verim ve biyomedikal içgörüler için foliküler gelişim, hormonal düzenleme ve hastalık araştırmalarının anlaşılmasına yardımcı olur.

Langhand yumurtalığının özelleşmiş granüloza ve teka hücrelerini anlamaya çalışıyoruz. Yumurtlama sırasında farklı noktalarda iki hücre tipi arasındaki diferansiyel gen ekspresyonunu inceliyoruz. Bu, yumurta üretimini sürdürülebilir bir şekilde artırmak için kullanılacak üreme verimliliği ve doğurganlığı hakkında bilgi sağlar.

Kanatlı Üreme Biyolojisi şu anda yeni nesil dizileme teknolojileri ve metabolik tahliller kullanılarak araştırılmaktadır. Bu, hem üreme dokularını hem de cinsel olgunluk ve yumurtlama ile ilgili hormonal etkileşimi incelemek için yapılır. Granüloza hücre tabakası her zaman sağlam bir tabaka olarak çıkmayabilir.
