Confocal Imaging of Confined Quiescent and Flowing Colloid-polymer Mixtures

1Chemical and Biomolecular Engineering Department, University of Houston


JoVE 51461

Confocal microscopy is used to image quiescent and flowing colloid-polymer mixtures, which are studied as model systems for attractive suspensions. Image analysis algorithms are used to calculate structural and dynamic metrics for the colloidal particles that measure changes due to geometric confinement.

Video-rate Scanning Confocal Microscopy and Microendoscopy

1Program in Biophysics, Harvard University, 2Division of Health Sciences and Technology, Harvard-MIT, 3Wellman Center for Photomedicine, Massachusetts General Hospital, Harvard Medical School


JoVE 3252

The complete construction of a custom, real-time confocal scanning imaging system is described. This system, which can be readily used for video-rate microscopy and microendoscopy, allows for an array of imaging geometries and applications not accessible using standard commercial confocal systems, at a fraction of the cost.

Live Cell Imaging of Primary Rat Neonatal Cardiomyocytes Following Adenoviral and Lentiviral Transduction Using Confocal Spinning Disk Microscopy

1Max-Planck-Institute for Molecular Biomedicine and Institute of Cell Biology, 2Department of Internal Medicine, Yale Cardiovascular Research Center and Section of Cardiovascular Medicine


JoVE 51666

This protocol describes a method of live cell imaging using primary rat neonatal cardiomyocytes following lentiviral and adenoviral transduction using confocal spinning disk microscopy. This enables detailed observations of cellular processes in living cardiomyocytes.

Cell Death Associated with Abnormal Mitosis Observed by Confocal Imaging in Live Cancer Cells

1Cancer Research Center, Sheba Medical Center, 2The Neufeld Cardiac Research Institute, Tel-Aviv University, 3Department of Physiology and Pharmacology, Tel-Aviv University, 4Imaging Unit, Sackler Faculty of Medicine, Tel-Aviv University, 5Biotechnology and Cell Signaling, Ecole Superieure de Biotechnologie Strasbourg, 6Department of Human Molecular Genetics and Biochemistry, Tel-Aviv University


JoVE 50568

The cytotoxic activity of the phenanthridine PJ-34 in cancer cells undergoing mitosis was documented in real time by live confocal imaging. PJ-34 eradicated human breast cancer MDA-MB-231 cells harboring extra-centrosomes in mitosis. Unlike normal bi-focal mitosis, the extra-centrosomes were not clustered in the two spindle poles in the presence of PJ-34.

In vivo Clonal Tracking of Hematopoietic Stem and Progenitor Cells Marked by Five Fluorescent Proteins using Confocal and Multiphoton Microscopy

1Light Microscopy Core Facility, NHLBI/NIH, 2Hematology Branch, NHLBI/NIH


JoVE 51669

Combinatorial 5 fluorescent proteins marking of hematopoietic stem and progenitor cells allows in vivo clonal tracking via confocal and two-photon microscopy, providing insights into bone marrow hematopoietic architecture during regeneration. This method allows non-invasive fate mapping of spectrally-coded HSPCs-derived cells in intact tissues for extensive periods of time following transplantation.

Confocal Imaging of Single Mitochondrial Superoxide Flashes in Intact Heart or In Vivo

1Mitochondria and Metabolism Center, Department of Anesthesiology and Pain Medicine, University of Washington


JoVE 50818

Confocal scanning microscopy is applied for imaging single mitochondrial events in perfused heart or skeletal muscles in live animal. Real-time monitoring of single mitochondrial processes such as superoxide flashes and membrane potential fluctuations enables the evaluation of mitochondrial function in a physiologically relevant context and during pathological perturbations.

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.

Analyzing Craniofacial Morphogenesis in Zebrafish Using 4D Confocal Microscopy

1Institute for Cell and Molecular Biology, The University of Texas at Austin


JoVE 51190

Time-lapse confocal imaging is a powerful technique useful for characterizing embryonic development. Here, we describe the methodology and characterize craniofacial morphogenesis in wild-type, as well as pdgfra, smad5, and smo mutant embryos.

Simultaneous pH Measurement in Endocytic and Cytosolic Compartments in Living Cells using Confocal Microscopy

1Department of Pediatrics, Faculty of Medicine and Health Sciences, Université de Sherbrooke, 2Biophotonics Core Facility, Centre de Recherche Clinique Etienne-Le Bel


JoVE 51395

Several methods are available for measuring intracellular pH but very few of these allow simultaneous measurement of cytoplasmic and organellar pH. Here, we describe in detail a rapid and accurate methodology to simultaneously measure cytoplasmic and vesicular pH by ratiometric imaging of living cells.

Real-time Imaging of Myeloid Cells Dynamics in ApcMin/+ Intestinal Tumors by Spinning Disk Confocal Microscopy

1Department of Oncology, INSERM U661, Functional Genomic Institute, 2Department of Anatomy, University of California


JoVE 51916

By using transgenic reporter mice and injectable fluorescent labels, long-term intravital spinning disk confocal microscopy enables direct visualization of myeloid cell behavior into intestinal adenoma in the ApcMin/+ colorectal cancer model.
