    Muscle Cryoinjury and Quantification of Regenerating Myofibers in Mice
    Authors:  Yori Endo, Mehran Karvar and Indranil Sinha, date: 06/05/2021, view: 159, Q&A: 0

    Cryoinjury, or injury due to freezing, is a method of creating reproducible, local injuries in skeletal muscle. This method allows studying the regenerative response following muscle injuries in vivo, thus enabling the evaluation of local and systemic factors that influence the processes of myofiber regeneration. Cryoinjuries are applicable to the

    Ex vivo Tissue Culture Protocols for Studying the Developing Neocortex
    Authors:  Takashi Namba, Christiane Haffner and Wieland B. Huttner, date: 05/20/2021, view: 536, Q&A: 0

    The size of the neocortex and its morphology are highly divergent across mammalian species. Several approaches have been utilized for the analysis of neocortical development and comparison among different species. In the present protocol (Note: This protocol requires basic knowledge of brain anatomy), we describe three ex vivo neocortical

    Generation of the Compression-induced Dedifferentiated Adipocytes (CiDAs) Using Hypertonic Medium

    Current methods to obtain mesenchymal stem cells (MSCs) involve sampling, culturing, and expanding of primary MSCs from adipose, bone marrow, and umbilical cord tissues. However, the drawbacks are the limited numbers of total cells in MSC pools, and their decaying stemness during in vitro expansion. As an alternative resource, recent ceiling

    Establishing an Adult Mouse Brain Hippocampal Organotypic Slice Culture System that Allows for Tracing and Pharmacological Manipulation of ex vivo Neurogenesis
    Authors:  Steffen Mayerl and Charles ffrench-Constant, date: 01/05/2021, view: 1042, Q&A: 0

    The function of the hippocampus depends on the process of adult hippocampal neurogenesis which underpins the exceptional neural plasticity of this structure, and is also frequently affected in CNS pathologies. Thus, manipulation of this process represents an important therapeutic goal. To identify potential strategies, organotypic adult brain

    Isolation of Extracellular Vesicles Derived from Mesenchymal Stromal Cells by Ultracentrifugation
    [Abstract] Extracellular vesicles (EVs) are a heterogeneous group of membranous vesicles that differ on their biogenesis and release pathways, such as exosomes, microvesicles and apoptotic bodies. They are involved in cell-to-cell communication delivering signal molecules (proteins, nucleic acids, lipids, etc.) that can regulate different ...
    Fluidigm Based Single-cell Gene Expression Library Preparation from Patient-derived Small Intestinal Organoids
    Authors:  Kohei Suzuki and Ryuichi Okamoto, date: 10/05/2020, view: 1012, Q&A: 0
    [Abstract] In this protocol, we describe our methods to isolate crypts from patients' biopsy samples and to culture human intestinal stem cells as it’s called “organoid.” Beyond that, we describe how to dissociate organoids cells into single cells for single-cell analysis as a further application. This protocol should provide investigators sufficient tools ...
    In vitro Differentiation of Human iPSC-derived Cardiovascular Progenitor Cells (iPSC-CVPCs)
    Authors:  Agnieszka D’Antonio-Chronowska, Matteo D’Antonio and Kelly A. Frazer, date: 09/20/2020, view: 2497, Q&A: 0
    [Abstract] Induced pluripotent stem cell derived cardiovascular progenitor cells (iPSC-CVPCs) provide an unprecedented platform for examining the molecular underpinnings of cardiac development and disease etiology, but also have great potential to play pivotal roles in the future of regenerative medicine and pharmacogenomic studies. Biobanks like iPSCORE ( ...
    Mesenchymal Stromal Cells Derived from Bone Marrow and Adipose Tissue: Isolation, Culture, Characterization and Differentiation
    [Abstract] Since their discovery, mesenchymal stromal cells (MSCs) have received a lot of attention, mainly due to their self-renewal potential and multilineage differentiation capacity. For these reasons, MSCs are a useful tool in cell biology and regenerative medicine. In this article, we describe protocols to isolate MSCs from bone marrow (BM-MSCs) and ...
    3D Organoid Formation from the Murine Salivary Gland Cell Line SIMS
    Authors:  Harleen K. Athwal and Isabelle M. A. Lombaert, date: 10/05/2019, view: 3456, Q&A: 0
    [Abstract] Salivary glands consist of multiple phenotypically and functionally unique cell populations, such as the acinar, ductal, and myoepithelial cells that help produce, modify, and secrete saliva (Lombaert et al., 2011). Identification of mechanisms and factors that regulate these populations has been of key interest, as salivary gland-related ...
    Isolation and Culture of Single Myofiber and Immunostaining of Satellite Cells from Adult C57BL/6J Mice
    Authors:  Shujie Chen, Hongrong Ding, Xiangping Yao and Liwei Xie, date: 07/20/2019, view: 4500, Q&A: 0
    [Abstract] Myofiber isolation followed with ex vivo culture could recapitulate and visualize satellite cells (SCs) activation, proliferation, and differentiation. This approach could be taken to understand the physiology of satellite cells and the molecular mechanism of regulatory factors, in terms of the involvement of intrinsic factors over SCs ...
