Hier beschreiben wir ein Protokoll zur Trennung von Dotter-, Granulosazellen und Thekazellen in präovulatorischen Follikeln von Vögeln. Diese präzise Handhabung ermöglicht kritische Untersuchungen der Rolle dieser Schichten für die Fortpflanzungsfunktion und hilft beim Verständnis der Follikelentwicklung, der Hormonregulation und der Krankheitsforschung, um den landwirtschaftlichen Ertrag zu steigern und biomedizinische Erkenntnisse zu gewinnen.

Wir versuchen, die spezialisierten Granulosa- und Thekazellen des Langhand-Eierstocks zu verstehen. Wir untersuchen die unterschiedliche Genexpression zwischen den beiden Zelltypen zu verschiedenen Zeitpunkten während des Eisprungs. Dies gibt Einblicke in die Fortpflanzungseffizienz und Fruchtbarkeit, die zur nachhaltigen Steigerung der Eiproduktion genutzt werden sollen.

Die Reproduktionsbiologie von Geflügel wird derzeit mit Hilfe von Next Generation Sequencing-Technologien und Stoffwechselassays untersucht. Dies geschieht, um sowohl das Fortpflanzungsgewebe als auch das hormonelle Zusammenspiel zu untersuchen, das an der Geschlechtsreife und dem Eisprung beteiligt ist. Die Granulosa-Zellschicht sieht nicht immer als intakte Schicht aus.
