Aqui, descrevemos um protocolo para separar células vitelinos, células da granulosa e teca em folículos pré-ovulatórios aviários. Esse manuseio preciso permite investigações críticas sobre o papel dessas camadas na função reprodutiva, auxiliando na compreensão do desenvolvimento folicular, regulação hormonal e pesquisa de doenças para melhorar o rendimento agrícola e insights biomédicos.

Procuramos entender as células especializadas da granulosa e da teca do ovário de Langhand. Estudamos a expressão gênica diferencial entre os dois tipos de células em diferentes pontos durante a ovulação. Isso fornece informações sobre eficiência reprodutiva e fertilidade que serão usadas para aumentar a produção de ovos de forma sustentável.

A Biologia Reprodutiva Avícola é atualmente investigada usando tecnologias de sequenciamento de última geração e ensaios metabólicos. Isso é feito para estudar os tecidos reprodutivos e a interação hormonal envolvida na maturidade sexual e na ovulação. A camada de células da granulosa nem sempre sai como uma folha intacta.
