  text: Neurons extend axons to form the complex circuitry of the mature brain. This
    depends on the coordinated response and continuous remodelling of the microtubule
    and F-actin networks in the axonal growth cone. Growth cone architecture remains
    poorly understood at nanoscales. We therefore investigated mouse hippocampal neuron
    growth cones using cryo-electron tomography to directly visualise their three-dimensional
    subcellular architecture with molecular detail. Our data showed that the hexagonal
    arrays of actin bundles that form filopodia penetrate and terminate deep within
    the growth cone interior. We directly observed the modulation of these and other
    growth cone actin bundles by alteration of individual F-actin helical structures.
    Microtubules with blunt, slightly flared or gently curved ends predominated in
    the growth cone, frequently contained lumenal particles and exhibited lattice
    defects. Investigation of the effect of absence of doublecortin, a neurodevelopmental
    cytoskeleton regulator, on growth cone cytoskeleton showed no major anomalies
    in overall growth cone organisation or in F-actin subpopulations. However, our
    data suggested that microtubules sustained more structural defects, highlighting
    the importance of microtubule integrity during growth cone migration.
