    Proteolytically released Lasso/teneurin-2 induces axonal attraction by interacting with latrophilin-1 on axonal growth cones

    Nickolai V Vysokov et al.
    Lasso and latrophilin-1 interact across the synapse, while shed Lasso binds latrophilin-1 on distant growth cones and attracts them, providing a universal mechanism for short- and long-range axonal guidance.

    Filopodial dynamics and growth cone stabilization in Drosophila visual circuit development

    Mehmet Neset Özel et al.
    Long-term live imaging in intact developing Drosophila brains reveals a role for N-Cadherin-mediated fast filopodial dynamics and growth cone stabilization during neural circuit assembly.

    Akt1-Inhibitor of DNA binding2 is essential for growth cone formation and axon growth and promotes central nervous system axon regeneration

    Hyo Rim Ko et al.
    Akt mediated S14 phosphorylation of Id2 augments its protein stability and growth cone localization, promoting growth cone formation and axon growth in the developing neuron and contributing to axon regeneration in the damaged hippocampus slice.

    Dephosphorylation of the NPR2 guanylyl cyclase contributes to inhibition of bone growth by fibroblast growth factor

    Leia C Shuhaibar et al.
    Fibroblast growth factor induces dephosphorylation and inactivation of the NPR2 guanylyl cyclase, thus decreasing cyclic GMP production in growth plate chondrocytes and contributing to FGF-dependent decreases in bone growth.

    Frazzled promotes growth cone attachment at the source of a Netrin gradient in the Drosophila visual system

    Orkun Akin, S Lawrence Zipursky
    Direct observation in the developing fly brain indicates that the response of a growth cone in a gradient of a guidance cue is adhesion to the source of the cue rather than attraction by the gradient.

    Altered bone growth dynamics prefigure craniosynostosis in a zebrafish model of Saethre-Chotzen syndrome

    Camilla S Teng et al.
    Sequential live imaging of abnormal skull bone fusion in zebrafish reveals a deeply conserved role of two transcription factors, Twist1 and Tcf12, in regulating stem cell activity during growth of the skull.

    Gradient-reading and mechano-effector machinery for netrin-1-induced axon guidance

    Kentarou Baba et al.
    Shootin1a, through its spatially regulated phosphorylation within growth cones, mediates the gradient reading and mechanoresponse for netrin-1-induced axon guidance.

    Ephrin-A/EphA specific co-adaptation as a novel mechanism in topographic axon guidance

    Felix Fiederling et al.
    A distinctive novel mechanism of ephrin-A/EphA signaling modulation in retinal growth cones ensures concurrent quantitative accuracy and adaptability of topographic hardwiring.

    Altered paracrine signaling from the injured knee joint impairs postnatal long bone growth

    Alberto Roselló-Díez et al.
    Genetic analyses in mice reveal a communication system between the knee joint and the developing bones that could be explored in studies addressing evolutionary changes in body proportions and in future therapies for growth disorders.
