    The proneural wave in the Drosophila optic lobe is driven by an excitable reaction-diffusion mechanism

    David J Jörg et al.
    A model of signalling pathways interacting with proneural gene expression explains the sequential patterning of the largest visual processing centre in the developing Drosophila brain.

    Cell-sized confinement controls generation and stability of a protein wave for spatiotemporal regulation in cells

    Shunshi Kohyama et al.
    A cell-sized fully confined space significantly controls the emergence and stability of a protein wave, resulting in intracellular spatiotemporal regulation driven by a reaction-diffusion mechanism.

    High-throughput mathematical analysis identifies Turing networks for patterning with equally diffusing signals

    Luciano Marcon et al.
    Realistic reaction-diffusion signaling networks that include cell-autonomous factors can robustly form self-organizing spatial patterns for any combination of diffusion coefficients without requiring differential diffusivity.

    Mapping out Min protein patterns in fully confined fluidic chambers

    Yaron Caspi, Cees Dekker
    The geometry selection rules of dynamic Min protein patterns are determined in fully confined fluidic chambers, showing that both oscillations and running waves are derivatives of spiral rotations that are established as the majority pattern.

    Design of biochemical pattern forming systems from minimal motifs

    Philipp Glock et al.
    Theoretical analysis and in vitro reconstitution of a biological reaction-diffusion system identify key functional motifs as well as underlying principles and enable rebuilding pattern formation in a modular fashion.

    Plasticity of cell migration resulting from mechanochemical coupling

    Yuansheng Cao et al.
    Computational and experimental studies show that different migration modes of eukaryotic cells are the result of the interplay between signaling waves and cell mechanics.

    Dynamics of BMP signaling and distribution during zebrafish dorsal-ventral patterning

    Autumn P Pomreinke et al.
    Patterning of the dorsal-ventral axis in zebrafish is mediated by a graded source-sink mechanism in which diffusing BMP, produced from a ventrally biased source, is inhibited by dorsally-produced chordin.

    Lymphangiogenic therapy prevents cardiac dysfunction by ameliorating inflammation and hypertension

    LouJin Song et al.
    Lymphangiogenic therapy VEGFCc156s improved angiotensin-II-induced impairments in heart function via novel mechanisms, which include transcriptional responses to alleviate inflammation and cardiac fibrosis, and systemic responses to ameliorate hypertension.

    Flower-like patterns in multi-species bacterial colonies

    Liyang Xiong et al.
    Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
