Near Infrared Optical Projection Tomography for Assessments of β-cell Mass Distribution in Diabetes Research

1Umeå Centre for Molecular Medicine, Umeå University, 2Cell Transplant Center, Diabetes Research Institute, University of Miami,, 3EMBL-CRG Systems Biology Program, Centre for Genomic Regulation, Catalan Institute of Research and Advanced Studies, 4Dept. of Computing Science, Umeå University


JoVE 50238

We describe the adaptation of optical projection tomography (OPT)1 to imaging in the near infrared spectrum, and the implementation of a number of computational tools. These protocols enable assessments of pancreatic β-cell mass (BCM) in larger specimens, increase the multichannel capacity of the technique and increase the quality of OPT data.

Long-term Culture of Human Breast Cancer Specimens and Their Analysis Using Optical Projection Tomography

1Breakthrough Breast Cancer Research Unit, Institute of Genetics and Molecular Medicine, University of Edinburgh, 2MRC Technology


JoVE 3085

We have developed a collagen-based in vitro assay which promotes proliferation and invasion from samples of all breast cancer subtypes. Optical Projection Tomography, a three dimensional microscopy technique was utilised to visualise and quantify tumour expansion. This assay may be used to quantify drug response of individual tumour samples.

Born Normalization for Fluorescence Optical Projection Tomography for Whole Heart Imaging

1Center for Systems Biology, Harvard Medical School, 2Center for Systems Biology, MGH - Massachusetts General Hospital, 3Institute for Biological and Medical Imaging, Technical University of Munich and Helmholtz Center Munich


JoVE 1389

We suggest a Born normalized approach for Optical Projection Tomography (BnOPT) that accounts for the absorption properties of imaged samples to obtain accurate and quantitative fluorescence tomographic reconstructions. We use the proposed algorithm to reconstruct the fluorescence molecular probe distribution within small animal organs.

Lensfree On-chip Tomographic Microscopy Employing Multi-angle Illumination and Pixel Super-resolution

1Electrical Engineering Department, University of California, Los Angeles, 2Bioengineering Department, University of California, Los Angeles, 3California NanoSystems Institute, University of California, Los Angeles


JoVE 4161

Lensfree optical tomography is a three-dimensional microscopy technique that offers a spatial resolution of <1 μm × <1 μm × <3 μm in x, y and z dimensions, respectively, over a large imaging-volume of 15-100 mm3, which can be particularly useful for integration with lab-on-a-chip platforms.

Using High Resolution Computed Tomography to Visualize the Three Dimensional Structure and Function of Plant Vasculature

1U.S. Department of Agriculture, 2Department of Viticulture and Enology, University of California - Davis, 3Hawkesbury Institute for the Environment, University of Western Sydney, 4Advanced Light Source, Lawrence Berkeley National Lab, 5Citrus Research & Education Center, University of Florida


JoVE 50162

High resolution x-ray computed tomography (HRCT) is a non-destructive diagnostic imaging technique that can be used to study the structure and function of plant vasculature in 3D. We demonstrate how HRCT facilitates exploration of xylem networks across a wide range of plant tissues and species.

Retrograde Perfusion and Filling of Mouse Coronary Vasculature as Preparation for Micro Computed Tomography Imaging

1Department of Pathology, Center for Cardiovascular Biology, and Institute for Stem Cell and Regenerative Medicine, University of Washington, 2Departments of Bioengineering and Medicine/Cardiology, University of Washington


JoVE 3740

Visualization of the coronary vessels is critical to advancing our understanding of cardiovascular diseases. Here we describe a method for perfusing murine coronary vasculature with a radiopaque silicone rubber (Microfil), in preparation for micro-Computed Tomography (μCT) imaging.

Quantitative Analysis and Characterization of Atherosclerotic Lesions in the Murine Aortic Sinus

1Department of Biochemistry and Biomedical Sciences, McMaster University, 2Thrombosis and Atherosclerosis Research Institute, McMaster University


JoVE 50933

We describe procedures to quantify and characterize atherosclerotic lesions in mouse models using precision sectioning of the aortic sinus and ascending aorta combined with histochemical and immunohistochemical analysis.

Sample Drift Correction Following 4D Confocal Time-lapse Imaging

1School of Biological Sciences, Monash University, 2Janelia Farm Research Campus, Howard Hughes Medical Institute


JoVE 51086

Time-lapse microscopy allows the visualization of developmental processes. Growth or drift of samples during image acquisition reduces the ability to accurately follow and measure cell movements during development. We describe the use of open source image processing software to correct for three dimensional sample drift over time.

Isolation and Culture of Neural Crest Cells from Embryonic Murine Neural Tube

1Department of Cell and Developmental Biology, Center for Stem Cell Biology, Vanderbilt University Medical Center, 2Department of Pharmacology, Center for Stem Cell Biology, Vanderbilt University Medical Center, 3Vanderbilt University Medical Center


JoVE 4134

Isolation of embryonic neural crest from the neural tube facilitates the use of in vitro methods for studying migration, self-renewal, and multipotency of neural crest.

Mesoscopic Fluorescence Tomography for In-vivo Imaging of Developing Drosophila

1Center for Systems Biology, Massachusetts General Hospital, 2Institute for Biological and Medical Imaging (IBMI), Technical University of Munich and Helmholtz Center Munich, 3Department of Genetics, Harvard Medical School and Howard Hughes Medical Institute


JoVE 1510

Mesoscopic fluorescence tomography operates beyond the penetration limits of tissue-sectioning fluorescence microscopy. The technique is based on multi-projection illumination and a photon transport description. We demonstrate in-vivo whole-body 3D visualization of the morphogenesis of GFP-expressing wing imaginal discs in Drosophila melanogaster.
