    Mouse Periosteal Cell Culture, in vitro Differentiation, and in vivo Transplantation in Tibial Fractures

    The periosteum covering the outer surface of bone contains skeletal stem/progenitor cells that can efficiently form cartilage and bone during bone repair. Several methods have been described to isolate periosteal cells based on bone scraping and/or

    A Simple Method to Generate Super-sensitive AID (ssAID)-based Conditional Knockouts using CRISPR-based Gene Knockout in Various Vertebrate Cell Lines
    Authors:  Kohei Nishimura and Tatsuo Fukagawa, date: 07/20/2021, view: 434, Q&A: 0

    Inducing loss of function of a target protein using methods such as gene knockout is a powerful and useful strategy for analyzing protein function in cells. In recent years, the CRISPR/Cas-9-based gene knockout technology has been widely used across

    CRISPR/Cas9-mediated Precise SNP Editing in Human iPSC Lines
    Authors:  Hanwen Zhang and Siwei Zhang, date: 06/20/2021, view: 1231, Q&A: 0

    Human induced pluripotent stem cells (hiPSCs) have been extensively used in the fields of developmental biology and disease modeling. CRISPR/Cas9 gene editing in iPSC lines often has a low frequency, which hampers its application in precise allele

    Generation and Maintenance of Homogeneous Human Midbrain Organoids
    Authors:  Henrik Renner, Martha Grabos, Hans R. Schöler and Jan M. Bruder, date: 06/05/2021, view: 1843, Q&A: 0

    Three-dimensional cell cultures (“organoids”) promise to better recapitulate native tissue physiology than traditional 2D cultures and are becoming increasingly interesting for disease modeling and compound screening efforts. While a

    Generation of Mouse Pluripotent Stem Cell-derived Trunk-like Structures: An in vitro Model of Post-implantation Embryogenesis

    Post-implantation mammalian embryogenesis involves profound molecular, cellular, and morphogenetic changes. The study of these highly dynamic processes is complicated by the limited accessibility of in utero development. In recent years, several

    Muscle Cryoinjury and Quantification of Regenerating Myofibers in Mice
    Authors:  Yori Endo, Mehran Karvar and Indranil Sinha, date: 06/05/2021, view: 1246, 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

    ...
    Ex vivo Tissue Culture Protocols for Studying the Developing Neocortex
    Authors:  Takashi Namba, Christiane Haffner and Wieland B. Huttner, date: 05/20/2021, view: 1716, 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

    Single or Repeated Ablation of Mouse Olfactory Epithelium by Methimazole
    Authors:  Sofia Håglin, Staffan Bohm and Anna Berghard, date: 04/20/2021, view: 1932, Q&A: 0

    Odor-detecting olfactory sensory neurons residing in the nasal olfactory epithelium (OE) are the only neurons in direct contact with the external environment. As a result, these neurons are subjected to chemical, physical, and infectious insults,

    Generation of Human iPSC-derived Neural Progenitor Cells (NPCs) as Drug Discovery Model for Neurological and Mitochondrial Disorders
    Authors:  Annika Zink, Pawel Lisowski and Alessandro Prigione, date: 03/05/2021, view: 2299, Q&A: 1

    The high attrition rate in drug development processes calls for additional human-based model systems. However, in the context of brain disorders, sampling live neuronal cells for compound testing is not applicable. The use of human induced

    ...
    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
