    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor et al.
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

    A predictive model of asymmetric morphogenesis from 3D reconstructions of mouse heart looping dynamics

    Jean-François Le Garrec et al.
    A precise sequence of left-right asymmetries, combined with mechanical constraints, is sufficient to drive the looped morphogenesis of the embryonic heart tube, with potential impact for congenital heart defects.

    MorphoGraphX: A platform for quantifying morphogenesis in 4D

    Pierre Barbier de Reuille et al.
    MorphoGraphX summarizes full 3D datasets as curved surface images (2.5D), enabling the efficient quantification of growth and gene expression data from large time-lapse volumetric datasets.

    A structure-based extracellular matrix expansion mechanism of fibrous tissue growth

    Nicholas S Kalson et al.
    Tendon fibroblast cells lay down a collagen matrix template during embryogenesis, and the expansion of this matrix drives post-natal tissue growth.

    The eukaryotic bell-shaped temporal rate of DNA replication origin firing emanates from a balance between origin activation and passivation

    Jean-Michel Arbona et al.
    The universal eukaryotic DNA replication kinetics is the consequence of simple physicochemical rules resulting from the localisation of potential replication origins at discrete sites and the diffusion of limiting origin firing factors in the nuclear space.

    Theoretical tool bridging cell polarities with development of robust morphologies

    Silas Boye Nissen et al.
    Biological shapes and morphological transitions can emerge from combining directed interactions between cells with apical-basal and planar cell polarity.

    Genomic regions controlling shape variation in the first upper molar of the house mouse

    Luisa F Pallares et al.
    An association mapping in wild mice revealed the first candidate loci for within-population molar shape variation and the phenotypic impact of such candidate loci was quantified and validated.

    The invariant cleavage pattern displayed by ascidian embryos depends on spindle positioning along the cell's longest axis in the apical plane and relies on asynchronous cell divisions

    Rémi Dumollard et al.
    Cell cycle asynchrony regulates apical cell shape to drive cell division orientation in the apical plane.

    Epidermal cell turnover across tight junctions based on Kelvin's tetrakaidecahedron cell shape

    Mariko Yokouchi et al.
    The three dimensional structure of epidermal cells in the stratum granulosum provides the basis for the homeostasis of the tight junction barrier during cell turnover in the skin.
