Qui, descriviamo un protocollo per separare il tuorlo, le cellule della granulosa e le cellule della teca nei follicoli preovulatori aviari. Questa manipolazione di precisione consente indagini critiche sul ruolo di questi strati nella funzione riproduttiva, aiutando la comprensione dello sviluppo follicolare, della regolazione ormonale e della ricerca sulle malattie per migliorare la resa agricola e le intuizioni biomediche.

Cerchiamo di comprendere le cellule specializzate della granulosa e della teca dell'ovaio di Langhand. Studiamo l'espressione genica differenziale tra i due tipi di cellule in diversi momenti durante l'ovulazione. Ciò fornisce informazioni sull'efficienza riproduttiva e sulla fertilità che verranno utilizzate per migliorare in modo sostenibile la produzione di ovuli.

La biologia riproduttiva del pollame è attualmente oggetto di studio utilizzando tecnologie di sequenziamento di nuova generazione e saggi metabolici. Questo viene fatto per studiare sia i tessuti riproduttivi che l'interazione ormonale coinvolta nella maturità sessuale e nell'ovulazione. Lo strato cellulare della granulosa potrebbe non essere sempre un foglio intatto.
