    Development of a Chemical Reproductive Aging Model in Female Rats

    Women are born with an abundant but finite pool of ovarian follicles, which naturally and progressively decreased during their reproductive years until menstrual periods stop permanently (menopause). Perimenopause represents the transition from reproductive to non-reproductive life. It is usually characterized by neuroendocrine, metabolic and

    Ligand and Carbohydrate Engagement (LACE) Assay and Fluorescence Quantification on Murine Neural Tissue
    Authors:  James M. Clegg and Thomas Pratt, date: 03/20/2021, view: 477, Q&A: 0

    The interaction between cell surface heparan sulphate and diffusible ligands such as FGFs is of vital importance for downstream signaling, however, there are few techniques that can be used to investigate this binding event. The ligand and carbohydrate engagement (LACE) assay is a powerful tool which can be used to probe the molecular interaction

    Optimized Immunostaining of Embryonic and Early Postnatal Mouse Brain Sections
    Authors:  Kawssar Harb, Michele Bertacchi and Michèle Studer, date: 01/05/2021, view: 1184, Q&A: 0

    The mammalian neocortex, the outer layer of the cerebrum and most recently evolved brain region, is characterized by its unique areal and laminar organization. Distinct cortical layers and areas can be identified by the protein expression of graded transcription factors and molecular determinants that define the identity of different projection

    A Parkinson’s Disease-relevant Mitochondrial and Neuronal Morphology High-throughput Screening Assay in LUHMES Cells

    Parkinson’s disease is a devastating neurodegenerative disorder affecting 2-3% of the population over 65 years of age. There is currently no disease-modifying treatment. One of the predominant pathological features of Parkinson’s disease is mitochondrial dysfunction, and much work has aimed to identify therapeutic compounds which can

    Whole-mount Immunohistochemistry of Adult Zebrafish Retina for Advanced Imaging
    Authors:  Mikiko Nagashima and Peter F. Hitchcock, date: 12/20/2020, view: 1130, Q&A: 0

    Immunohistochemistry is a widely used technique to examine the expression and subcellular localization of proteins. This technique relies on the specificity of antibodies and requires adequate penetration of antibodies into tissues. The latter is especially challenging for thick specimens, such as embryos and other whole-mount preparations. Here

    Staining and Quantitative Analysis of Myelinating Oligodendrocytes in the Mouse Grey Matter
    Authors:  Matthew Swire and Charles ffrench-Constant, date: 10/20/2020, view: 1018, 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 ...
    Organotypic Slice Culture of the Embryonic Mouse Brain
    Authors:  James M. Clegg and Thomas Pratt, date: 07/05/2020, view: 1238, Q&A: 0
    [Abstract] Organotypic slice culture is a powerful technique for exploring the embryonic development of the mammalian brain. In this protocol we describe a basic slice culture technique we have used for two sets of experiments: axon guidance transplant assays and bead culture assays.
    Rapid Generation of Human Neuronal Cell Models Enabling Inducible Expression of Proteins-of-interest for Functional Studies
    [Abstract] CRISPR-Cas9 technology has transformed the ability to edit genomic sequences and control gene expression with unprecedented ease and scale. However, precise genomic insertions of coding sequences using this technology remain time-consuming and inefficient because they require introducing adjacent single-strand cuts through Cas9 nickase action and ...
    Laser Capture Micro-dissection (LCM) of Neonatal Mouse Forebrain for RNA Isolation
    Authors:  Achira Roy, Mei Deng, Kimberly A. Aldinger, Ian A. GLass and Kathleen J. Millen, date: 01/05/2020, view: 3222, Q&A: 0
    [Abstract] Precise and reproducible isolation of desired cell types or layers from heterogeneous tissues is crucial to analyze specific gene profiles and molecular interactions in vivo. Forebrain is the core site of higher functions, like cognition and memory consolidation. It is composed of heterogeneous and distinct cell types, interconnected to ...
    Gallyas Silver Impregnation of Myelinated Nerve Fibers
    Authors:  Sabitha Joseph, Hauke B. Werner and Judith Stegmüller, date: 11/20/2019, view: 2339, Q&A: 0
    [Abstract] In the nervous system of vertebrates, nerve impulse propagation is accelerated by the ensheathment of neuronal axons with myelin. Myelin sheaths are molecularly specialized, lipid-rich plasma membrane extensions of Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system (CNS). To visualize myelinated nerve ...
