    Murine HSCs contribute actively to native hematopoiesis but with reduced differentiation capacity upon aging

    Petter Säwen, Mohamed Eldeeb ... David Bryder
    Using a lineage tracing model, it is demonstrated that adult murine hematopoiesis is contingent on the continuous output from HSCs, with quantitative contributions that are dependent on lineage-type and age.

    Kinetics of blood cell differentiation during hematopoiesis revealed by quantitative long-term live imaging

    Kevin Yueh Lin Ho, Rosalyn Leigh Carr ... Guy Tanentzapf
    A long-term multi-organ co-culture system coupled with quantitative imaging to visualize blood cell cycle progression, analyze polarized blood cell mitosis, and track blood cell differentiation kinetics during Drosophila hematopoiesis in homeostatic condition and following infection.

    Pigment cell progenitor heterogeneity and reiteration of developmental signaling underlie melanocyte regeneration in zebrafish

    William Tyler Frantz, Sharanya Iyengar ... Craig J Ceol
    Zebrafish pigment cell progenitors are a heterogeneous class of adult tissue-resident cells which reiterate developmental signaling during melanocyte regeneration.

    Cell-to-cell heterogeneity in Sox2 and Bra expression guides progenitor motility and destiny

    Michèle Romanos, Guillaume Allio ... Bertrand Bénazéraf
    Spatial variations of transcription factor expression regulate the choice of progenitors to stay in their niche or to migrate into neural and mesodermal tissues.

    Programmed conversion of hypertrophic chondrocytes into osteoblasts and marrow adipocytes within zebrafish bones

    Dion Giovannone, Sandeep Paul ... J Gage Crump
    Cartilage cells transition through a proliferative intermediate to give rise to bone and marrow fat cells in long bones.

    MiRNA-128 regulates the proliferation and neurogenesis of neural precursors by targeting PCM1 in the developing cortex

    Wei Zhang, Paul Jong Kim ... Li Zeng
    During early cortical development, microRNA-128 regulates the homeostasis of neural stem cells by targeting PCM1, a protein that is critical for cell division.

    Transcriptional landscape of myogenesis from human pluripotent stem cells reveals a key role of TWIST1 in maintenance of skeletal muscle progenitors

    In Young Choi, Hotae Lim ... Gabsang Lee
    Using multiple genetic reporter system in human pluripotent stem cells, a transcriptional database for human early myogenesis has been established.

    5-Hydroxymethylcytosine-mediated active demethylation is required for mammalian neuronal differentiation and function

    Elitsa Stoyanova, Michael Riad ... Nathaniel Heintz
    5-Hydroxymethylcytosine-mediated active DNA demethylation occurs in postmitotic neurons, and is required for their terminal differentiation and function.

    Lactate receptor HCAR1 regulates neurogenesis and microglia activation after neonatal hypoxia-ischemia

    Lauritz Kennedy, Emilie R Glesaaen ... Johanne E Rinholm
    HCAR1 knockout mice are unable to initiate brain tissue repair after a hypoxic-ischemic injury.
