ここでは、鳥類の排卵前卵胞で卵黄、顆粒膜細胞、およびテカ細胞を分離するためのプロトコルについて説明します。この精密な取り扱いにより、生殖機能におけるこれらの層の役割に関する重要な調査が可能になり、卵胞の発生、ホルモン調節、および農業収量と生物医学的洞察を向上させるための疾患研究の理解に役立ちます。

私たちは、ラングハンド卵巣の特殊な顆粒膜細胞とテカ細胞を理解しようとしています。私たちは、排卵中の異なる時点での2つの細胞タイプ間の遺伝子発現の違いを研究しています。これにより、生殖効率と生殖能力に関する洞察が得られ、卵子生産を持続的に強化するために使用されます。

家禽生殖生物学は現在、次世代シーケンシング技術と代謝アッセイを使用して研究されています。これは、生殖組織と、性的成熟と排卵に関与するホルモンの相互作用の両方を研究するために行われます。顆粒膜細胞層は、常に無傷のシートとして剥がれるとは限りません。
