    Revised roles of ISL1 in a hES cell-based model of human heart chamber specification

    Roberto Quaranta et al.
    Loss and gain-of-function investigation uncovers a regulatory network controlling human heart chamber specification in which the cardiac precursor gene ISL1 accelerates ventricular induction and antagonizes retinoic acid-driven atrial commitment.

    Hippo signaling determines the number of venous pole cells that originate from the anterior lateral plate mesoderm in zebrafish

    Hajime Fukui et al.
    The Hippo signaling restricts the number of SHF cardiomyocytes in the venous pole by negatively regulating Bmp-Smad signaling in the cells of lateral plate mesoderm.

    Spatially resolved RNA-sequencing of the embryonic heart identifies a role for Wnt/β-catenin signaling in autonomic control of heart rate

    Silja Barbara Burkhard, Jeroen Bakkers
    A genome wide transcriptome dataset of the embryonic zebrafish heart with high spatial resolution was established and used to identify a novel mechanism regulating pacemaker function.

    Epigenetic modulation of type-1 diabetes via a dual effect on pancreatic macrophages and β cells

    Wenxian Fu et al.
    A short treatment of the NOD mouse model of type-1 diabetes with I-BET151, a small molecule bromodomain blocker, provides long-term protection from disease by inducing macrophages to adapt an anti-inflammatory tenor whilst promoting islet β cell regeneration.

    Elementary sensory-motor transformations underlying olfactory navigation in walking fruit-flies

    Efrén Álvarez-Salvado et al.
    A high-throughput behavioral paradigm and computational modeling are used to decompose olfactory navigation in walking Drosophila melanogaster into a set of quantitative relationships between sensory input and motor output.

    Functional limb muscle innervation prior to cholinergic transmitter specification during early metamorphosis in Xenopus

    Francois M Lambert et al.
    Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.

    A novel source of arterial valve cells linked to bicuspid aortic valve without raphe in mice

    Lorriane Eley et al.
    Identification of a novel source of progenitor cells that form arterial valve leaflets and that, when disrupted, can lead to bicuspid arterial valve, the most common human cardiac malformation.
