細胞や組織に対して酸素を効果的に届けるプロセスを指し、特に灌流培養や3D培養系、organ-on-a-chip などの生体模倣システムにおいて極めて重要な要素です。酸素は細胞の代謝や生存に不可欠なため、適切な濃度・分布で供給することが、細胞機能の維持や再現性のある実験結果の取得に直結します。

This refers to the process of effectively delivering oxygen to cells and tissues, and it is a critical factor, particularly in bio-mimetic systems such as perfusion culture, 3D culture systems, and organ-on-a-chip devices. Since oxygen is essential for cellular metabolism and survival, supplying it at the appropriate concentration and distribution is directly linked to maintaining cellular function and obtaining reproducible experimental results.
