Arterial-venous segregation by selective cell sprouting: an alternative mode of blood vessel formation.

7 Oct 2009 Blood vessels form de novo (vasculogenesis) or upon sprouting of capillaries from preexisting vessels (angiogenesis). With high-resolution imaging of zebrafish vascular development, we uncovered a third mode of blood vessel formation whereby the ... Read more...

Chemokine signaling guides regional patterning of the first embryonic artery.

29 Sep 2009 The aorta traverses the body, yet little is known about how it is patterned in different anatomical locations. Here, we show that the aorta develops from genetically distinct endothelial cells originating from diverse locations within the embryo. ... Read more...

Hedgehog and Bmp polarize hematopoietic stem cell emergence in the zebrafish dorsal aorta.

30 May 2009 Hematopoietic stem cells (HSCs) are first detected in the floor of the embryonic dorsal aorta (DA), and we investigate the signals that induce the HSC program there. We show that while continued Hedgehog (Hh) signaling from the overlying midline ... Read more...
