    A study of zebrafish identifies an innate mechanism of blood vessel formation through the transdifferentiation of lymphatic endothelial cells, and provides in vivo evidence for a link between cell ontogeny and functionality in endothelial cells.

    Arterial development relies on the timely and MYC-dependent suppression of endothelial metabolism and the cell cycle in pre-arterial endothelial cells through Notch signalling.

    Single-cell analysis of blood vessels in the alveolus, the site of chronic disease and virus-induced lung injury, reveals two intermingled endothelial cell types with specialized gas exchange and stem cell functions.

    The transient reactivation of ETV2 in adult human endothelial cells reprograms these cells to become adaptable vasculogenic endothelia that in three-dimensional matrices self-assemble into vascular networks that can transport blood and physiologically arborize organoids and decellularized tissues.

    The zebrafish cloche gene is required for the formation of most endothelial and haematopoietic cells, however, it has been difficult to isolate; this study reveals that cloche encodes a PAS-domain-containing bHLH transcription factor, and a mammalian orthologue can partially rescue cloche mutants, indicating a possible conserved role in mammals.

    This study identifies a crucial role for fatty acid oxidation (FAO) in endothelial cells during angiogenesis, and reveals that fatty-acid-derived carbons are used for the de novo synthesis of nucleotides, and hence FAO stimulates vessel sprouting by increasing endothelial cell proliferation.

    Bone homeostasis and repair declines with ageing and the mechanisms regulating the relationship between bone growth and blood vessel formation have remained unknown; this mouse study identifies the endothelial cells that promote the formation of new bone, a small microvessel subtype that can be identified by high CD31 and high Emcn expression.

    In mice, chronic stimulation by repetitive sounds, whisker deflection, motor activity or seizures during a postnatal developmental critical period, leads to permanent reductions in brain microvascular density, an effect that impairs oxygen delivery to neurons but can be prevented by blocking nitric oxide signalling.

    Gene-expression studies are used to elucidate the relationship between cholesterol regulation and angiogenesis: apolipoprotein A-1 binding protein (AIBP) is found to enhance cholesterol influx from endothelial cells to high-density lipoprotein, and the resulting cholesterol depletion alters membrane lipid order in the vasculature, leading to decreased vascular endothelial growth factor receptor signalling.

    This study identifies a deubiquitinase (DUB) that specifically recognises and cleaves linear ubiquitin chains, implicating linear (de)ubiquitination in Wnt signalling and angiogenesis; mutations in gumby cause defects in angiogenesis in mice, and structural and biochemical analysis shows that gumby encodes a linear-ubiquitin-specific DUB.

    To understand how blood vessels form and function, scientists require reproducible systems that mimic living tissues. An innovative approach based on microfabricated vessels provides a key step towards this goal.

    Evidence from mice and humans indicates that peripartum cardiomyopathy (PPCM) is a vascular disease caused by excessive anti-angiogenic signalling in the peripartum period of pregnancy and that pre-eclampsia and multiple gestation are important risk factors for the development of PPCM.

    Skin-cancer stem cells secrete a factor that organizes a blood-supply system to fuel tumour growth. But the same factor has another sinister function — it stimulates the stem cells to propagate uncontrollably. See Letter p.399

    These authors describe a molecular pathway by which endothelial cells sustain liver regeneration after surgical resection. Activation of vascular endothelial growth factor-A receptor-2 in a defined subpopulation of liver endothelial cells leads to the upregulation of the endothelial-specific transcription factor Id1, which in turn induces Wnt2 and hepatocyte growth factor, which are secreted from the endothelial cells and trigger hepatocyte proliferation.

    Here it is shown that the end products of lipid oxidation — ω-(2-carboxyethyl) pyrrole and other related pyrroles — are generated during inflammation and wound healing, and accumulate at high levels in ageing tissues in mice and in highly vascularized tumours in murine and human melanomas. These carboxyalkylpyrroles are recognized by Toll-like receptor 2 on endothelial cells, setting off a chain of events that leads to the growth of new blood vessels.

    To form new blood vessels, the endothelial tip cells of two existing vessels come together by the process of anastomosis. But how do they find each other? Macrophages seem to provide a bridge and mediate their union.

    The protein ephrin-B2 is known to be upregulated during angiogenesis — the growth of new blood vessels — but its precise function has been unclear. Here it is shown that signalling through ephrin-B2 controls vessel sprouting. Mechanistically, ephrin-B2 seems to function in part by regulating the internalization of vascular endothelial growth factor receptors (VEGFRs). The results indicate that blocking ephrin-B2 signalling might be an alternative to blocking VEGFR function to disrupt angiogenesis in tumours.

    During embryonic development, blood vessels remodel in response to blood flow. Here, a genetic pathway is described through which this mechanosensory stimulus is integrated with early developmental signals to remodel vessels of the aortic arch in zebrafish. It is found that the flow-induced transcription factor klf2a is required to induce the expression of an endothelial-specific microRNA, activating signalling through the growth factor Vegf.

    Prevailing models propose that coronary arteries in the developing heart are formed from progenitor cells originating in the proepicardium. It is found here, however, that these arteries arise from angiogenic sprouts of the major vein that returns circulating blood to the embryonic heart. Thus some differentiated venous cells retain developmental plasticity and respond to local signals to convert to coronary arteries, capillaries and veins.
