Bone morphogenetic protein (BMP) signaling is essential for neural crest development in several vertebrates. Genetic experiments in the mouse have shown that Bmp2 is essential for the genesis of migratory neural crest cells. Using several markers and a transgenic reporter approach, we now show that neural crest cells are induced in Bmp2 null mutant embryos,(More)
Arterial morphogenesis is one of the most critical events during embryonic vascular development. Although arterial fate specification is mainly controlled by the Notch signaling pathway, arterial-venous patterning is modulated by a number of guidance factors. How these pathways are regulated is still largely unknown. Here, we demonstrate that endothelial(More)
Local endocytic events involving receptors for axon guidance cues play a central role in controlling growth cone behaviour. Yet, little is known about the fate of internalized receptors, and whether the sorting events directing them to distinct endosomal pathways control guidance decisions. Here, we show that the receptor Plexin-D1 contains a sorting motif(More)
Tbx1 belongs to the family of T-box containing transcription factors. In humans, TBX1 is implicated in the etiology of the DiGeorge syndrome. Inactivation of the Tbx1 gene in mice produces a variety of malformations including abnormal branching of the heart outflow tract, deficiencies in the branchial arch derivatives, agenesis of pharyngeal glands and(More)
RATIONALE Arteriogenesis is the process of formation of arterial conduits. Its promotion is an attractive therapeutic strategy in occlusive atherosclerotic diseases. Despite the functional and clinical importance of arteriogenesis, the biology of the process is poorly understood. Synectin, a gene previously implicated in the regulation of vascular(More)
This paper describes a proteome analysis and changes in endogenous abscisic acid (ABA) contents during seed development of Araucaria angustifolia (Bert.) O. Ktze. Megagametophytes and embryonic axis tissues exhibited a similar ABA variation pattern during seed development, reaching maximum values at the pre-cotyledonary stage. The embryonic axis protein(More)
OBJECTIVE The H2.0-like homeobox transcription factor (HLX) plays an essential role in visceral organogenesis in mice and has been shown to regulate angiogenic sprouting in vitro and in zebrafish embryos. We therefore examined the role of HLX in vascular development in mouse and avian embryos. APPROACH AND RESULTS In situ hybridization showed that Hlx is(More)
Myeloid cells are important contributors to arteriogenesis, but their key molecular triggers and cellular effectors are largely unknown. We report, in inflammatory monocytes, that the combination of chemokine receptor (CCR2) and adhesion receptor (β2 integrin) engagement leads to an interaction between activated Rac2 and Myosin 9 (Myh9), the heavy chain of(More)
