Abstract

The Notch signalling pathway is repeatedly employed during embryonic development and adult homeostasis of a variety of tissues. In particular, its frequent involvement in the regulation of stem and progenitor cell maintenance and proliferation, as well as its role in binary fate decisions in cells that are destined to differentiate, is remarkable. Here, we review its role in the development of haematopoietic stem cells during vertebrate embryogenesis and put it into the context of Notch's functions in arterial specification, angiogenic vessel sprouting and vessel maintenance. We further discuss interactions with other signalling cascades, and pinpoint open questions and some of the challenges that lie ahead.
