    Efficient Superovulation and Egg Collection from Mice
    Authors:  Miyuki Shindo, Kenji Miyado, Woojin Kang, Maki Fukami and Mami Miyado, date: 06/05/2022, view: 547, Q&A: 0
    [Abstract]

    Superovulation is a method used to reduce the number of mice used per experiment by increasing the egg number. Conventionally, superovulation for obtaining mouse eggs involves the use of equine chorionic gonadotropin (eCG) for stimulation and human CG for induction. Female mice of the C57BL/6 inbred strain spontaneously ovulate approximately 10

    Protocol for Isolation of Cardiomyocyte from Adult Mouse and Rat
    Authors:  Huiliang Zhang and Peter S. Rabinovitch, date: 05/20/2022, view: 875, Q&A: 0
    [Abstract]

    The isolation of intact single adult cardiomyocytes from model animals, mouse and rat, is an essential tool for cardiac molecular and cellular research. While several methods are reported for adult mouse cardiomyocyte isolation, the viability and yield of the isolated cells have been variable. Here, we describe step-by-step protocols for high

    Immunomagnetic Isolation and Enrichment of Microvascular Endothelial Cells from Human Adipose Tissue
    [Abstract]

    Human adipose tissue-resident microvascular endothelial cells are not only garnering attention for their emergent role in the pathogenesis of obesity-related metabolic disorders, but are also of considerable interest for vascular tissue engineering due, in part, to the abundant, accessible, and uniquely dispensable nature of the tissue. Here, we

    Production of Recombinant Hepatitis B virus (HBV) and Detection of HBV in Infected Human Liver Organoids
    Authors:  Tanvir Hossain, Shahla Romal and Tokameh Mahmoudi, date: 04/20/2022, view: 539, Q&A: 0
    [Abstract]

    The absence of long term, primary untransformed in vitro models that support hepatitis B virus (HBV) infection and replication have hampered HBV pre-clinical research, which was reflected in the absence of a curative therapy until recently. One of the limitations for in vitro HBV research has been the absence of high titer and pure recombinant HBV

    Isolation of tdTomato Expressing Inter-follicular Epidermal Melanocytes or Keratinocytes from Mouse Tail Skin
    Authors:  Samuel Pop, Oscar Urtatiz and Catherine D. Van Raamsdonk, date: 04/20/2022, view: 1106, Q&A: 0
    [Abstract]

    The epidermis is the outermost layer of the skin. It is made up of mostly keratinocytes along with a small number of melanocytes and Langerhans cells. Melanocytes produce a pigment called melanin, which is transferred to the keratinocytes, and protects these cells from damage from UV radiation, as well as generating hair and skin colours. In this

    Low-viscosity Matrix Suspension Culture for Human Colorectal Epithelial Organoids and Tumoroids
    [Abstract]

    Three-dimensional culture of human normal colorectal epithelium and cancer tissue as organoids and tumoroids has transformed the study of diseases of the large intestine. A widely used strategy for generating patient-derived colorectal organoids and tumoroids involves embedding cells in domes of extracellular matrix (ECM). Despite its success,

    Isolation and Culture of Cranial Neural Crest Cells from the First Branchial Arch of Mice
    Authors:  Hiroki Ueharu, Jingwen Yang, Yoshihiro Komatsu and Yuji Mishina, date: 04/05/2022, view: 623, Q&A: 0
    [Abstract]

    Craniofacial anomalies (CFA) are a diverse group of deformities, which affect the growth of the head and face. Dysregulation of cranial neural crest cell (NCC) migration, proliferation, differentiation, and/or cell fate specification have been reported to contribute to CFA. Understanding of the mechanisms through which cranial NCCs contribute

    Differentiation of Human Induced Pluripotent Stem Cell into Macrophages
    Authors:  Harriet Douthwaite, Aitor Bermejo Arteagabeitia and Subhankar Mukhopadhyay, date: 03/20/2022, view: 1034, Q&A: 0
    [Abstract]

    As a model to interrogate human macrophage biology, macrophages differentiated from human induced pluripotent stem cells (hiPSCs) transcend other existing models by circumventing the variability seen in human monocyte-derived macrophages, whilst epitomizing macrophage phenotypic and functional characteristics over those offered by macrophage-like

    Generation, Maintenance and HBV Infection of Human Liver Organoids
    Authors:  Shahla Romal, Tanvir Hossain and Tokameh Mahmoudi, date: 03/20/2022, view: 1109, Q&A: 0
    [Abstract]

    Hepatitis B virus (HBV) infection represents a major public health problem infecting approximately 400 million people worldwide. Despite the availability of a preventive vaccine and anti-viral therapies, chronic HBV infection remains a major health issue because it increases the risk of developing liver cirrhosis and hepatocellular carcinoma

    Three-dimensional Models of the Nasopharynx for the Study of Epstein-Barr Virus Infection
    [Abstract]

    The ubiquitous and cancer-associated Epstein-Barr virus (EBV) is associated with nearly all cases of nasopharyngeal carcinoma (NPC). Nasopharyngeal tissue is comprised of both pseudostratified and stratified epithelium, which are modeled in three-dimensional (3-D) cell culture. The cellular origin of EBV-associated NPC is as yet unknown, but both
