    Direct Reprogramming of Mouse Embryonic Fibroblasts to Conventional Type 1 Dendritic Cells by Enforced Expression of Transcription Factors
    Authors:  Fábio F. Rosa, Cristiana F. Pires, Olga Zimmermannova and Carlos-Filipe Pereira, date: 05/20/2020, view: 201, Q&A: 0
    Ectopic expression of transcription factor combinations has been recently demonstrated to reprogram differentiated somatic cells towards the dendritic cell (DC) lineage without reversion to a multipotent state. DCs have the ability to induce potent ...
    Direct Reprogramming of Mouse Embryonic Fibroblasts to Conventional Type 1 Dendritic Cells by Enforced Expression of Transcription Factors

    [Abstract] Ectopic expression of transcription factor combinations has been recently demonstrated to reprogram differentiated somatic cells towards the dendritic cell (DC) lineage without reversion to a multipotent state. DCs have the ability to induce potent and long-lasting adaptive immune responses. In particular, conventional type 1 DCs (cDC1s) excel on ...
    Application of Mechanical Forces on Drosophila Embryos by Manipulation of Microinjected Magnetic Particles
    Authors:  Arturo D’Angelo and Jérôme Solon, date: 05/05/2020, view: 419, Q&A: 0
    [Abstract] Cells generate mechanical forces to shape tissues during morphogenesis. These forces can activate several biochemical pathways and trigger diverse cellular responses by mechano-sensation, such as differentiation, division, migration and apoptosis. Assessing the mechano-responses of cells in living organisms requires tools to apply controlled local ...
    Live Cell Imaging of Male Meiosis in Arabidopsis by a Landmark-based System
    [Abstract] Live cell imaging has tremendously promoted our understanding of cellular and subcellular processes such as cell division. Here, we present a step-by-step protocol for a robust and easy-to-use live cell imaging approach to study male meiosis in the plant Arabidopsis thaliana as recently established. Our method relies on the concomitant ...
    A Modified Semisolid Clonal Culture for Identification of B-1 and B-2 Progenitor Colony Forming Ability of Mouse Embryonic Hemogenic Endothelial Cells
    Authors:  Michihiro Kobayashi and Momoko Yoshimoto, date: 05/05/2020, view: 487, Q&A: 0
    [Abstract] The search for the origin of the first hematopoietic stem cells (HSCs) in the mouse embryo has been a hot topic in the field of developmental hematopoiesis. Detecting lymphoid potential is one of the supportive evidence to show the definitive hematopoietic activity of HSCs. However, the first B-lymphoid potential in the mouse embryos are reported ...
    Auxin-mediated Protein Degradation in Caenorhabditis elegans
    Authors:  Michael A. Q. Martinez and David Q. Matus, date: 04/20/2020, view: 669, Q&A: 0
    [Abstract] The auxin-inducible degron (AID) technology was recently adapted for use in the nematode Caenorhabditis elegans. Rapid degradation of C. elegans proteins tagged with an AID is mediated by a plant-specific F-box protein, transport inhibitor response 1 (TIR1), and occurs only in the presence of the phytohormone auxin. The first ...
    Bimolecular Fluorescence Complementation (BiFC) for Studying Sarcomeric Protein Interactions in Drosophila
    Authors:  Océane Marescal, Frieder Schöck and Nicanor González-Morales, date: 04/05/2020, view: 343, Q&A: 0
    [Abstract] Protein-protein interactions in Drosophila myofibrils are essential for their function and formation. Bimolecular Fluorescence Complementation (BiFC) is an effective method for studying protein interactions and localization. BiFC relies on the reconstitution of a monomeric fluorescent protein from two half-fragments when in proximity. Two ...
    Self-organization Assay for Min Proteins of Escherichia coli in Micro-droplets Covered with Lipids
    Authors:  Shunshi Kohyama, Kei Fujiwara, Natsuhiko Yoshinaga and Nobuhide Doi, date: 03/20/2020, view: 412, Q&A: 0
    [Abstract] The Min system determines the cell division plane of bacteria. As a cue of spatiotemporal regulation, the Min system uses wave propagation of MinD protein (Min wave). Therefore, the reconstitution of the Min wave in cell-sized closed space will lead to the creation of artificial cells capable of cell division. The Min waves emerge via coupling ...
    Testing Bone Formation Induction by Calvarial Injection Assay in vivo
    Authors:  Narelle E McGregor, Ingrid J Poulton, Emma C Walker and Natalie A Sims, date: 03/20/2020, view: 524, Q&A: 0
    [Abstract] Bone formation occurs during embryogenesis, skeletal growth and during the process of skeletal renewal throughout life. In the process of bone formation, osteoblasts lay down a collagen-containing matrix, termed osteoid, which is gradually hardened by incorporation of mineral crystals. Although osteoblasts can be induced to differentiate and to ...
    Lipid Mixing Assay for Murine Myoblast Fusion and Other Slow Cell-cell Fusion Processes
    [Abstract] Lipid mixing (redistribution of lipid probes between fusing membranes) has been widely used to study early stages of relatively fast viral and intracellular fusion processes that take seconds to minutes. Lipid mixing assays are especially important for identification of hemifusion intermediates operationally defined as lipid mixing without content ...
    Tandem Tag Assay Optimized for Semi-automated in vivo Autophagic Activity Measurement in Arabidopsis thaliana roots
    Authors:  Adrian N. Dauphinee, Jonas A. Ohlsson and Elena A. Minina, date: 03/05/2020, view: 674, Q&A: 0
    [Abstract] Autophagy is the main catabolic process in eukaryotes and plays a key role in cell homeostasis. In vivo measurement of autophagic activity (flux) is a powerful tool for investigating the role of the pathway in organism development and stress responses. Here we describe a significant optimization of the tandem tag assay for detection of ...
