Blood vessels arise from progenitor cells, grow and branch by sprouting from preexisting vessels and remodel by splitting longitudinally. A new study proposes an additional mechanism. It seems that vascularization can proceed through the mechanical translocation and expansion of existing vessels, which loop into vascularising tissue (pages 657–664).
