Novel three-dimensional analysis tool for vascular trees indicates complete micro-networks, not single capillaries, as the angiogenic endpoint in mice overexpressing human VEGF(165) in the brain

Abstract

To adequately supply tissues with oxygen and nutrients, the formation of functional vascular networks requires generation of normal, healthy vessels and their arrangement into an effective network architecture. While our knowledge about the development of single vessels significantly increased during the last years, mechanisms responsible for network formation are still poorly understood. This is probably due to the lack of suitable methods for quantification of structural properties of microvascular networks. Previously we showed tha Show more
