The study of blood pressure regulation, coagulation, inflammation, atherosclerosis as well as angiogenesis marks the five major pillars of vascular research. The recent advances in the understanding of the molecular mechanisms driving organotypic vascular differentiation and function reflect the emergence of a sixth branch of vascular biology, for which we coined the term ’Angioscience’. Angioscience is aimed at (i) unraveling in much greater mechanistic detail the molecular repertoire of organotypically differentiated cells of the vessel wall (not just restricted to endothelial cells) all the way to the single cell level, (ii) elucidating the multidirectional molecular crosstalk of vessel wall cells with the cells of their microenvironment as well as systemic effects controlled by organotypic vasculatures, (iii) dissecting niche functions of organotypic vasculatures, and (iv) unraveling the fate maps of different organotypic vasculatures in health and disease. Based on these conceptual considerations, the CRC 1366 ’Vascular Control of Organ Function’ was inaugurated in 2019 to focus on the active roles of endothelial cells and surrounding mural cells in the control of physiological and pathological processes in organ-specific tissue microenvironments, the so-called vascular niches. Organotypic vascular cells, particularly organ-specific endothelial cells, control vascular niche functions during organ development as well as under diverse physiological and pathophysiological conditions by secreting vascular signaling molecules, the so-called angiokines, as well as by generating and expressing additional angiocrine substances, such as molecules of the extracellular matrix, adhesion molecules and other surface receptors. Therefore, blood vessels exert important regulatory and control functions for the development of disease processes, and they are key targets for novel and advanced therapies for metabolic and inflammatory diseases and cancer (angiotargeted therapies).
