    Single-cell expression profiling reveals dynamic flux of cardiac stromal, vascular and immune cells in health and injury

    Nona Farbehi, Ralph Patrick ... Richard P Harvey
    Comprehensive scRNA-seq analysis of cardiac stromal cells in healthy and injured hearts reveals novel cell types and non-linear cell dynamics, providing new insights into cardiac inflammation, fibrosis and repair.

    The myocardium utilizes a platelet-derived growth factor receptor alpha (Pdgfra)–phosphoinositide 3-kinase (PI3K) signaling cascade to steer toward the midline during zebrafish heart tube formation

    Rabina Shrestha, Tess McCann ... Joshua Bloomekatz
    Research on heart tube assembly using zebrafish reveals a pivotal role for intrinsic Pdgfra–PI3K signaling in steering the movement of the myocardium and polarizing myocardial cell protrusions.

    Hypertrophic chondrocytes serve as a reservoir for marrow-associated skeletal stem and progenitor cells, osteoblasts, and adipocytes during skeletal development

    Jason T Long, Abigail Leinroth ... Matthew J Hilton
    Hypertrophic chondrocytes of the growth plate undergo a process of dedifferentiation to generate marrow associated skeletal stem and progenitor cells (SSPCs), which ultimately re-differentiate into cells of the osteoblast or adipocyte lineages during skeletal development.

    Macrophages promote endothelial-to-mesenchymal transition via MT1-MMP/TGFβ1 after myocardial infarction

    Laura Alonso-Herranz, Álvaro Sahún-Español ... Mercedes Ricote
    Macrophage production of MT1-MMP upon MI contributes to adverse cardiac remodeling and worsened function by promoting EndMT via TGFB, suggesting MT1-MMP inhibition as a therapeutic option for patients with MI.

    Drosophila PDGF/VEGF signaling from muscles to hepatocyte-like cells protects against obesity

    Arpan C Ghosh, Sudhir Gopal Tattikota ... Norbert Perrimon
    A muscle-derived signaling molecule suppresses excessive accumulation of lipids in the Drosophila adipose tissue by activating the Pi3K/Akt/mTOR signaling cascade in the Drosophila hepatocyte-like cells.
