A powerful combination of cell labelling, genetic tools and rapid imaging techniques in vivo has now led to a high-resolution description of lumen formation during angiogenesis in zebrafish. The study reveals a haemodynamic-force-driven and myosin-II-dependent cellular mechanism (termed inverse membrane blebbing) as the basis for lumen expansion in unicellular and multicellular angiogenic sprouts.
