TL;DR: It is shown here that VEGF-A controls angiogenic sprouting in the early postnatal retina by guiding filopodial extension from specialized endothelial cells situated at the tips of the vascular sprouts.

TL;DR: The emerging principles of vascular growth provide exciting new perspectives, the translation of which might overcome the current limitations of pro- and antiangiogenic medicine.

TL;DR: Evidence is presented that delta-like 4 (Dll4)–Notch1 signalling regulates the formation of appropriate numbers of tip cells to control vessel sprouting and branching in the mouse retina, and modulators of Dll4 or Notch signalling, such as γ-secretase inhibitors developed for Alzheimer's disease, might find usage as pharmacological regulators of angiogenesis.

TL;DR: It is shown that ECs relied on glycolysis rather than on oxidative phosphorylation for ATP production and that loss of the gly colytic activator PFKFB3 in ECs impaired vessel formation.

TL;DR: Although PC deficiency appears to have direct effects on EC number before E 13.5, the subsequent increased VEGF-A levels may further abrogate microvessel architecture, promote vascular permeability, and contribute to formation of the edematous phenotype observed in late gestation PDGF-B and PDGFR-beta knock out embryos.
