Intracellular transport is vital for the function, survival and architecture of every eukaryotic cell. Long range transport in animal cells is thought to depend exclusively on microtubule tracks. This study reveals an unexpected actin-dependent but microtubule-independent mechanism for long range transport of vesicles. Vesicles organize their own actin tracks by recruiting the actin nucleation factors Spire1, Spire2 and Formin-2, which assemble an extensive actin network from the vesicles’ surfaces. The network connects the vesicles with each other and with the plasma membrane. Vesicles move directionally along these connections in a Myosin 5b-dependent manner to converge and to reach the cell surface. The overall outward directed movement of the vesicle-actin-network is driven by recruitment of vesicles to the plasma membrane in the periphery of the oocyte. Being organized in a dynamic vesicle-actin-network allows vesicles to move in a local random manner and a global directed manner at the same time: they can reach any position in the cytoplasm, but also move directionally to the cell surface as a collective. Thus, collective movement within a network is a powerful and flexible mode of vesicle transport.
