Expansion of a vascular network requires breaking through the basement membrane, a highly crosslinked barrier that tightly adheres to mature vessels. Angiogenic endothelial cells are now shown to form podosome rosettes that are able to focally degrade the extracellular matrix, prior to vascular sprouting in tumour angiogenesis.
