このプロトコルは、胚移植プロセスに影響を与える関連分子を評価するためのシンプルで効率的な胚移植 in vitro モデルを確立するための方法論を説明しています。

胚移植は、妊娠を成功させるための最初のステップであり、その生物学的基盤を理解し、不妊症の課題に対処するために重要です。この研究の目的は、制御された条件下で胚の子宮内膜の相互作用を分析するための一貫したプラットフォームを確立することです。このin vitroモデルに基づいて、超高濃度のエストロゲンは胚着床リスクを大幅に減少させるのに対し、プロゲステロンの補給はこれらの悪影響を依存的に軽減できることがわかりました。

この研究は、体外受精のための制御された卵巣刺激中の新鮮胚移植における妊娠リスクを改善するための新しい洞察と治療戦略を提供します。三次元培養システムと比較して、このin vitroモデルは、ほとんどの研究室で確立できるシンプルで迅速で費用対効果の高いプラットフォームを提供し、高い再現性と信頼性を示すため、生殖生物学の分野における研究開発に有利なツールとなっています。
