    Brain-localized and Intravenous Microinjections in the Larval Zebrafish to Assess Innate Immune Response
    Authors:  Alison M. Rojas and Celia E. Shiau, date: 04/05/2021, view: 290, Q&A: 0
    [Abstract]

    Creating a robust and controlled infection model is imperative for studying the innate immune response. Leveraging the particular strengths of the zebrafish model system, such as optical transparency, ex utero development, and large clutch size, allows for the development of methods that yield consistent and reproducible results. We created a

    Bioorthogonal Labeling and Chemoselective Functionalization of Lung Extracellular Matrix
    Authors:  Zihan Ling, Yunhui Xing, Emily Reinoso Jacome, Shierly W. Fok and Xi Ren, date: 02/20/2021, view: 816, Q&A: 0
    [Abstract]

    Decellularized extracellular matrix (ECM) biomaterials derived from native tissues and organs are widely used for tissue engineering and wound repair. To boost their regenerative potential, ECM biomaterials can be functionalized via the immobilization of bioactive molecules. To enable ECM functionalization in a chemoselective manner, we have

    Wounding Caenorhabditis elegans with Glass Wool
    [Abstract]

    Research on wound healing majorly relies on rat, mice and other animal models. However, an alternative animal model ought to be brought in the field, pertaining to the stringent ethical issues owing to the use of animals in research. In this regard, Caenorhabdits elegans, a miniature model nematode gains the great attention of the researchers in

    Histological and Immunohistochemical Examination of Stem Cell Proliferation and Reepithelialization in the Wounded Skin
    Authors:  Rupali Gund, Ravindra Zirmire, Haarshaadri J., Gaurav Kansagara and Colin Jamora, date: 01/20/2021, view: 852, Q&A: 0
    [Abstract]

    The skin is the largest organ that protects our body from the external environment and it is constantly exposed to pathogenic insults and injury. Repair of damage to this organ is carried out by a complex process involving three overlapping phases of inflammation, proliferation and remodeling. Histological analysis of wounded skin is a convenient

    Measuring Bone Volume at Multiple Densities by Micro-computed Tomography
    Authors:  Emma C. Walker, Narelle E. McGregor, Audrey S. M. Chan and Natalie A. Sims, date: 01/05/2021, view: 1058, Q&A: 0
    [Abstract]

    Bone strength is controlled by both bone mass, and the organization and quality of the bone material. The current standard method for measuring bone mass in mouse and rat studies is micro-computed tomography. This method typically uses a single threshold to identify bone material in the cortical and trabecular regions. However, this single

    Using the Parafilm-assisted Microdissection (PAM) Method to Sample Rodent Nucleus Accumbens
    [Abstract] Microdissection techniques are very important for anatomical and functional studies focused on neuroscience, where it is often necessary microdissect specific brain areas to perform molecular or anatomical analyses. The parafilm®-assisted microdissection (PAM) was previously described and involves the microdissection of tissue ...
    Staining and Quantitative Analysis of Myelinating Oligodendrocytes in the Mouse Grey Matter
    Authors:  Matthew Swire and Charles ffrench-Constant, date: 10/20/2020, view: 952, Q&A: 0
    [Abstract] Oligodendrocytes generate distinct patterns of myelination throughout the CNS. Variations in myelination along axons may enable neurons to fine-tune conduction velocities and alter signal synchronisation. Here we outline a staining protocol permitting the assessment of the number and length of myelin sheaths formed by oligodendrocyte in the mouse ...
    Double Labeling of PDGFR-β and α-SMA in Swine Models of Acute Kidney Injury to Detect Pericyte-to-Myofibroblast Transdifferentation as Early Marker of Fibrosis
    [Abstract] Growing evidences suggest that peritubular capillaries pericytes are the main source of scar-forming myofibroblasts during chronic kidney disease (CKD), as well as early phases of acute kidney injury (AKI). In a swine model of sepsis and I/R (Ischemia Reperfusion) injury-induced AKI we demonstrated that renal pericytes are able to ...
    Preparing Viable Hippocampal Slices from Adult Mice for the Study of Sharp Wave-ripples
    Authors:  Linhua Liu, Xiaojing Zhou and Jian-young Wu, date: 10/05/2020, view: 1025, Q&A: 0
    [Abstract] We describe a protocol for preparing acute brain slices which can produce robust hippocampal sharp wave-ripples (SWRs) in vitro. The protocol is optimized for its simplicity and reliability for the preparation of solutions, slicing, and recovery incubation. Most slices in almost every mouse prepared though the protocol expressed vigorous ...
    Surgical Induction of Endometriosis in Female Mice
    Authors:  Alejandra Escudero-Lara, David Cabañero and Rafael Maldonado, date: 09/20/2020, view: 1022, Q&A: 0
    [Abstract] Endometriosis is a common gynecological disease characterized by the presence of endometrial tissue outside the uterine cavity. It is frequently associated with pain, infertility and a reduced quality of life, and it lacks adequate treatment. Several rodent models of endometriosis have been developed through heterologous and homologous ...
