    The regulation of oocyte maturation and ovulation in the closest sister group of vertebrates

    Shin Matsubara et al.
    Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.

    Dpp dependent Hematopoietic stem cells give rise to Hh dependent blood progenitors in larval lymph gland of Drosophila

    Nidhi Sharma Dey et al.
    Identification of Hematopoietic stem cells (HSCs) in the genetically amenable organism Drosophila melanogaster paves the path to address HSC biology, both in normal and pathophysiological conditions.

    Sustained expression of HeyL is critical for the proliferation of muscle stem cells in overloaded muscle

    Sumiaki Fukuda et al.
    Proliferating muscle stem cells in overloaded muscle require special molecular mechanisms that differ from well-known myogenic differentiation model.

    Control of cyclic oligoadenylate synthesis in a type III CRISPR system

    Christophe Rouillon et al.
    Generation of the anti-viral second messenger cyclic oligoadenylate by type III CRISPR systems is tightly controlled in response to viral RNA load and sequence.

    Anisotropic organization of circumferential actomyosin characterizes hematopoietic stem cells emergence in the zebrafish

    Mylene Lancino et al.
    Emergence of hematopoietic stem cells from an aortic component is a unique phenomenon of cell extrusion, with no equivalent in cell biology, and which is adapted to environmental constraints exerted by endothelial cells and hemodynamics forces.

    Two receptor tyrosine phosphatases dictate the depth of axonal stabilizing layer in the visual system

    Satoko Hakeda-Suzuki et al.
    Two receptor tyrosine phosphatases having overlapping function for the determination of the final axon stabilizing layer is encoded for their cumulative cytoplasmic activity and ligand specificity in the visual system.

    A sleep state in Drosophila larvae required for neural stem cell proliferation

    Milan Szuperak et al.
    A role for sleep in developmental neurogenesis is revealed using a new system for studying sleep during nascent periods.

    mTORC1 is necessary but mTORC2 and GSK3β are inhibitory for AKT3-induced axon regeneration in the central nervous system

    Linqing Miao et al.
    The kinase AKT acts as a nodal point that coordinates both positive and negative cues to regulate the regeneration of central nervous system axons in adult mice.

    Evaluating mesenchymal stem cell therapy for sepsis with preclinical meta-analyses prior to initiating a first-in-human trial

    Manoj M Lalu et al.
    A rigorous and transparent evaluation of mesenchymal stem cell therapy for sepsis suggests it may be efficacious, although the strength of these findings is tempered by threats to validity in the studies that were included.
