Advances in pancreatic islet monolayer culture on glass surfaces enable super-resolution microscopy and insights into beta cell ciliogenesis and proliferation

Jeffrey Alan Hubbell, Olivier Burri, Miriella Carmela Pasquier, Andreas Wiederkehr, Steinunn Baekkeskov Hanahan, Edward Allen Phelps, Gabriele Galliverti, Chiara Cianciaruso

A robust and reproducible method for culturing monolayers of adherent and well-spread primary islet cells on glass coverslips is required for detailed imaging studies by super-resolution and livecell microscopy. Guided by an observation that dispersed isle ...

Visible spectrum extended-focus optical coherence microscopy for label-free sub-cellular tomography

Theo Lasser, Paul James Marchand, Séverine Coquoz, David Nguyen, Adrien Charles-François Raymond Descloux, Arno Pino Bouwens, Daniel Pawel Szlag, Jérôme Extermann, Miguel Sison

We present a novel extended-focus optical coherence microscope (OCM) attaining 0.7 μm axial and 0.4 μm lateral resolution maintained over a depth of 40 μm, while preserving the advantages of Fourier domain OCM. Our system uses an ultra-broad spectrum from ...

Quantitative telomeric chromatin isolation protocol for human cells

Joachim Lingner, Sophie Redon, Jana Majerská

The ends of eukaryotic chromosomes, known as telomeres, consist of repetitive DNA sequences, multiple proteins and noncoding RNAs. Telomeres are dynamic structures that play crucial roles as guardians of genome stability and tumor suppressors. Defects in t ...

Label-free three-dimensional imaging of Caenorhabditis elegans with visible optical coherence microscopy

Theo Lasser, Paul James Marchand, Séverine Coquoz, Johan Auwerx, Arno Pino Bouwens, Laurent Mouchiroud, Daniel Pawel Szlag, Vincenzo Sorrentino

Fast, label-free, high-resolution, three-dimensional imaging platforms are crucial for high-throughput in vivo time-lapse studies of the anatomy of Caenorhabditis elegans, one of the most commonly used model organisms in biomedical research. Despite the ne ...

Ultrathin Alumina Membranes as Scaffold for Epithelial Cell Culture from the Intestine of Rainbow Trout

Philippe Renaud, Songmei Wu, Kristin Schirmer, Carolin Drieschner

Permeable membranes are indispensable for in vitro epithelial barrier models. However, currently available polymer-based membranes are low in porosity and relatively thick, resulting in a limited permeability and unrealistic culture conditions. In this stu ...

Impedance Spectroscopy for Single Cell Analysis and Dispensing

David Vincent Bonzon

Flow cytometry is an essential tool in biology and medicine with applications in immunodeficiency diagnostic, immunosurveillence, organ transplantation in addition to its basic research usage. Before the widespread use of the Fluorescent-Activated Cell Sor ...

Resistance of echovirus 11 to ClO2 is associated with enhanced host receptor use, altered entry routes and high fitness

Virginie Bachmann, Tamar Kohn, Hyunjin Shim, Qingxia Zhong, Jeffrey David Jensen, Anna Carratala Ripolles

Waterborne viruses can exhibit resistance to common water disinfectants, yet the mechanisms that allow them to tolerate disinfection are poorly understood. Here, we generated echovirus 11 (E11) with resistance to chlorine dioxide (ClO2) by experimental evo ...

Advanced technologies to control stem-cell based organogenesis

Nathalie Brandenberg

Organoids represent the first in vitro cell culture systems that closely resemble native tissues in terms of cellular composition, architecture and key aspects of physiology. Through the discovery of these cultures, researchers could demonstrate that stem ...

Microfluidic and Electrokinetic Manipulation of Single Cells

Samuel Kilchenmann

Traditional cell assays report on the average results of a cell population. However, a wide range of new tools are being developed for a fundamental understanding of single cell's functionality. Nonetheless, the current tools are either limited in their th ...

Miniaturized Dielectric Elastomer Actuator for Mechanical Stimulation of Monolayer Cell Cultures

Alexandre Poulin

This thesis advances the field of dielectric elastomer actuators (DEAs) through the development of device designs, fabrication processes, strain characterization technique and modelling tool. It provides the first demonstration that DEAs can be interfaced ...

Dielectric Elastomer Actuator for Mechanical Loading of 2D Cell Cultures

Samuel Rosset, Herbert Shea, Alexandre Poulin

We demonstrate the use of dielectric elastomer actuators (DEAs) for mechanical stimulation of cells in vitro. The development of living tissues is regulated by their mechanical environment through the modification of fundamental cellular functions such as ...

Transposable Elements and Their KRAB-ZFP Controllers Regulate Gene Expression in Adult Tissues

Didier Trono, Priscilla Turelli, Annamaria Kauzlaric, Julien Léonard Duc, Helen Mary Rowe, Sandra Eloise Kjeldsen, Gabriela Ecco, Marco Cassano, Michaël Imbeault, Andrea Coluccio

KRAB-containing zinc finger proteins (KRAB-ZFPs) are early embryonic controllers of transposable elements (TEs), which they repress with their cofactor KAP1 through histone and DNA methylation, a process thought to result in irreversible silencing. Using a ...
