Immunohistological Labeling of Microtubules in Sensory Neuron Dendrites, Tracheae, and Muscles in the Drosophila Larva Body Wall
1Disease Mechanism Research Core, RIKEN Brain Science Institute, 2Graduate School of Science and Engineering, Saitama University
To understand how complex cell shapes, such as neuronal dendrites, are achieved during development, it is important to be able to accurately assay microtubule organization. Here we describe a robust immunohistological labeling method to examine microtubule organization of dendritic arborization neuron sensory dendrites, trachea, muscle, and other Drosophila larva body wall tissues.
Localizing Protein in 3D Neural Stem Cell Culture: a Hybrid Visualization Methodology
1Neural Regeneration Laboratory and Ottawa Institute of Systems Biology, Department of Biochemistry, Microbiology and Immunology, University of Ottawa, 2Carleton Immersive Media Studio, Azrieli School of Architecture and Urbanism, Carleton University
Here, we describe how to produce, expand, and immunolabel postnatal hippocampal neural progenitor cells (NPCs) in three-dimensional (3D) culture. Next, using hybrid visualization technologies, we demonstrate how digital images of immunolabelled cryosections can be used to reconstruct and map the spatial position of immunopositive cells throughout the entire 3D neurosphere.
Single Cell Transfection in Chick Embryos
Department of Medical Neurobiology, Hadassah Medical School - Hebrew University
Using fine tip micropipettes we inject plasmid DNA into subdomains of chicken somites or neural tubes. The concentration of the plasmid is adjusted to generate single transfected cells. We then allow the cells to develop into clonal populations.
Alginate Hydrogels for Three-Dimensional Organ Culture of Ovaries and Oviducts
Medicinal Chemistry and Pharmacognosy, University of Illinois at Chicago
Culture of normal cells in their three-dimensional context represents an alternative method to study early events required for cellular transformation and tumorigenesis. This method is used to grow normal ovarian and oviductal cells to study early events in ovarian cancer formation.
Focussed Ion Beam Milling and Scanning Electron Microscopy of Brain Tissue
Centre of interdisciplinary electron microscopy, École Polytechnique Fédérale de Lausanne
This protocol describes how resin embedded brain tissue can be prepared and imaged in the three dimensions in the focussed ion beam, scanning electron microscope.

Quantitation of DNA double-strand breaks on the basis of γH2AX foci has become an invaluable tool, particularly in radiation biology, for the evaluation of tissue radiosensitivity and effects of radiation modifying compounds. Here we demonstrate the use of an immunofluorescence assay for quantitation of γH2AX foci in tissue samples.
Method for Novel Anti-Cancer Drug Development using Tumor Explants of Surgical Specimens
1Department of Neurological Surgery, The Ohio State University Medical Center, 2Department of Pathology, The Ohio State University Medical Center
Here, we established a method for drug efficacy testing with surgical specimens of brain tumors, termed “tumor explant method”. With this method, we can evaluate drug efficacy without breaking the microenvironment of solid tumors. To validate reliability of this method, we describe representative data with our glioma specimen treated with the current first-line chemotherapeutic agent, temozolomide.
Batch Immunostaining for Large-Scale Protein Detection in the Whole Monkey Brain
1Cognitive Neuroscience Unit, Montreal Neurological Institute, 2Ècole d’Optomètrie, Universitè de Montrèal, 3Department of Psychology, McGill University
Large-scale immunodetection of target proteins across the entire primate brain is possible by employing novel tissue embedding and sectioning methods combined with the use of creative apparatus for batch staining of multiple free-floating sections at a given time.
Combining Lipophilic dye, in situ Hybridization, Immunohistochemistry, and Histology
1Department of Biology, University of Iowa, 2Molecular Targeting Technologies, Inc.
A combination of different techniques to maximize data collection from mouse tissue is presented.
Correlative Light and Electron Microscopy (CLEM) as a Tool to Visualize Microinjected Molecules and their Eukaryotic Sub-cellular Targets
Department of Molecular Microbiology, University of Texas Southwestern Medical Center
The CLEM technique has been adapted to analyze ultrastructural morphology of membranes, organelles, and subcellular structures affected by microinjected molecules. This method combines the powerful techniques of micromanipulation/microinjection, confocal fluorescent microscopy, and electron microscopy to allow millimeter to multi-nanometer resolution. This technique is amenable to a wide variety of applications.
