既存の血管から新たな毛細血管が分岐・成長して形成される生物学的プロセスである。発生過程、創傷治癒、がん、再生医療など多くの生理・病理的状況で重要な役割を果たす。特に三次元培養系やorgan-on-a-chipなどの生体模倣環境では、酸素・栄養の供給ネットワークとしての血管構造の構築が不可欠であり、血管新生の誘導・解析が研究の中心になる。

It is a biological process in which new capillaries branch off from existing blood vessels and grow. It plays a crucial role in many physiological and pathological conditions, including development, wound healing, cancer, and regenerative medicine. In particular, in bio-mimetic environments such as three-dimensional culture systems and organ-on-a-chip devices, the establishment of vascular structures as networks for oxygen and nutrient supply is essential, making the induction and analysis of angiogenesis a central focus of research.
