Understanding the cellular basis of vascular disease is crucial to developing preventive and therapeutic strategies. At WCC 2026, the Vascular Biology session will explore the pathobiology of atherosclerosis, angiogenesis, vascular remodelling, and endothelial dysfunction. Discussions will include inflammation, oxidative stress, and the interplay between metabolic disorders and vascular integrity. Key advances in microvascular research, therapeutic angiogenesis, and targeted drug delivery systems will also be presented by global translational researchers.
