Three-dimensional Confocal Analysis of Microglia/macrophage Markers of Polarization in Experimental Brain Injury

1Department of Neuroscience, IRCCS - Istituto di Ricerche Farmacologiche Mario Negri


JoVE 50605

A way to gain new insights into the complexity of the brain inflammatory response is presented. We describe immunofluorescence-based protocols followed by three-dimensional confocal analysis to investigate the pattern of co-expression of microglia/macrophage phenotype markers in a mouse model of focal ischemia.

Mouse Fetal Whole Intestine Culture System for Ex Vivo Manipulation of Signaling Pathways and Three-dimensional Live Imaging of Villus Development

1Cell and Developmental Biology, University of Michigan, 2Department of Biosciences and Nutrition, Karolinska Instituet Novum


JoVE 51817

Improved imaging technology is allowing three-dimensional imaging of organs during development. Here we describe a whole organ culture system that allows live imaging of the developing villi in the fetal mouse intestine.

Analysis of Cell Migration within a Three-dimensional Collagen Matrix

1Institute of Immunology & Experimental Oncology, Center for Biomedical Education and Research (ZBAF), Witten/Herdecke University


JoVE 51963

Cell migration is a biological phenomenon that is involved in a plethora of physiological, such as wound healing and immune responses, and pathophysiological processes, like cancer. The 3D-collagen matrix migration assay is a versatile tool to analyze the migratory properties of different cell types within in a 3D physiological-like environment.

Investigating the Three-dimensional Flow Separation Induced by a Model Vocal Fold Polyp

1Department of Mechanical and Aerospace Engineering, The George Washington University, 2Department of Mechanical and Aeronautical Engineering, Clarkson University


JoVE 51080

Vocal fold polyps can disrupt vocal fold dynamics and thus can have devastating consequences on a patient's ability to communicate. Three-dimensional flow separation induced by a wall-mounted model polyp and its impact on the wall pressure loading are examined using particle image velocimetry, skin friction line visualization, and wall pressure measurements.

Three Dimensional Cultures: A Tool To Study Normal Acinar Architecture vs. Malignant Transformation Of Breast Cells

1Department of Internal Medicine, University of Michigan Comprehensive Cancer Center, 2Department of Pathology, University of Michigan Comprehensive Cancer Center


JoVE 51311

Three dimensional culture of mammary epithelial cells on a reconstituted basement membrane is a useful method to recapitulate the in vivo architecture of the benign breast, and to differentiate the malignant phenotype from the benign breast phenotype. Importantly, this system can be applied to study invasive carcinomas in other tissues.

Quantification of Breast Cancer Cell Invasiveness Using a Three-dimensional (3D) Model

1Department of Physiology and Pharmacology, Schulich School of Medicine and Dentistry, University of Western Ontario, 2Department of Oncology, Schulich School of Medicine and Dentistry, University of Western Ontario, 3Lawson Health Research Institute


JoVE 51341

This article provides detailed methodologies for the use of three-dimensional (3D) assays to quantify breast cancer cell invasion. Specifically, we discuss the procedures required to set up such assays, quantification, and data analysis, as well as methods to examine the loss of membrane integrity that occurs when cells invade.

Three Dimensional Vestibular Ocular Reflex Testing Using a Six Degrees of Freedom Motion Platform

1Department of Neuroscience, Erasmus MC, 2TNO Human Factors


JoVE 4144

A method is described to measure three-dimensional vestibulo ocular reflexes (3D VOR) in humans using a six degrees of freedom (6DF) motion simulator. The gain and misalignment of the 3D angular VOR provide a direct measure of the quality of vestibular function. Representative data on healthy subjects are provided

Slide Preparation Method to Preserve Three-dimensional Chromatin Architecture of Testicular Germ Cells

1Division of Reproductive Sciences, Division of Developmental Biology, Perinatal Institute, Cincinnati Children's Hospital Medical Center, 2Department of Pediatrics, University of Cincinnati College of Medicine


JoVE 50819

The material here describes a method developed to preserve the three-dimensional chromatin structure of testicular germ cells. This has been termed the three-dimensional (3D) slide method. This method improves sensitivity for detection of subnuclear structures and is applicable for immunofluorescence, DNA, and RNA fluorescence in situ hybridization (FISH).

Characterization of Thermal Transport in One-dimensional Solid Materials

1Department of Mechanical Engineering, Iowa State University


JoVE 51144

The TET (transient electro-thermal) technique is an effective approach developed to measure the thermal diffusivity of solid materials.

Three-dimensional Imaging of Nociceptive Intraepidermal Nerve Fibers in Human Skin Biopsies

1Department of Neurology, University of Michigan, 2Department of Internal Medicine, University of Michigan


JoVE 50331

In order to study the changes of nociceptive intraepidermal nerve fibers (IENFs) in painful neuropathies (PN), we developed protocols that could directly examine three-dimensional morphological changes observed in nociceptive IENFs. Three-dimensional analysis of IENFs has the potential to evaluate the morphological changes of IENF in PN.
