Cell culture imaging using microimpedance tomography

We present a novel, inexpensive, and fast microimpedance tomography system for two-dimensional imaging of cell and tissue cultures. The system is based on four-electrode measurements using 16 planar microelectrodes (5 mum x 4 mm) integrated into a culture ...

Induction of A9 dopaminergic neurons from neural stem cells improves motor function in an animal model of Parkinsons disease

Romain Zufferey

Neural stem cells (NSCs) are widely endorsed as a cell source for replacement strategies in neurodegenerative disease. However, their usefulness is currently limited by the inability to induce specific neurotransmitter phenotypes in these cells. In order t ...

Optical Investigation of Skin Morphology and Anatomy

Theo Lasser, Rainer Leitgeb, Roland Michaely

This project investigates skin anatomy and physiology by three optical, non-invasive techniques: Fringe projection topography mainly for the investigation of tissue topography Parallel laser Doppler blood flow imaging for the investigation of tissue micro ...

APOBEC3-independent interferon-induced viral clearance in hepatitis B virus transgenic mice

Didier Trono, Priscilla Turelli, Bastien Mangeat, Sonia Verp, Stéphanie Jost

Interferon (IFN) has been part of the standard treatment of chronic hepatitis B infection for more than 2 decades, yet the mechanism of action of this antiviral remains poorly understood. It was recently observed that members of the human APOBEC family of ...

Bipolar resistivity profiling of 3D tissue culture

Philippe Renaud, Yann Barrandon, Olof Pontus Linderholm, Jonas Vannod

We describe a new low-cost technique for continuous monitoring of the thickness of biofilms and tissue cultures, and we demonstrate the advantage of using electrodes of different dimensions to probe different depths of a sample. We have used electric imped ...

In vitro breeding of Brassica juncea L. to enhance metal accumulation and extraction properties

Jean-Paul Schwitzguebel, Erika Nehnevajova

In vitro breeding and somaclonal variation were used as tools to improve the potential of Indian mustard (Brassica juncea L.) to extract and accumulate toxic metals. Calli from B. juncea were cultivated on a modified MS medium supplemented with 10–200 μM C ...

Two-dimensional microimpedance imaging for cell culture monitoring

Olof Pontus Linderholm

This thesis presents the fabrication and design of an impedance imaging sensor, and its application to monitoring in-vitro skin culture. Three-dimensional tissue cultures are becoming increasingly important in biological and medical research. There is, how ...

Two-dimensional impedance imaging of cell migration and epithelial stratification

Philippe Renaud, Yann Barrandon, Thomas Michael Braschler, Olof Pontus Linderholm, Jonas Vannod

We present a miniaturized impedance imaging system, developed for 2D imaging of cell and tissue culture. The system is based on 16 microelectrodes (5 µm × 4 mm). An equivalent circuit for four-point (tetrapolar) impedance spectra was developed and validate ...

Nodal stability determines signaling range

Daniel Constam, Yixing Chen

Secreted TGFbeta proteins of the Nodal family pattern the vertebrate body axes and induce mesoderm and endoderm . Nodal proteins can act as morphogens , but the mechanisms regulating their activity and signaling range are poorly understood. In particular, ...

Non-GMO approach for the improvement of heavy metal accumulation and extraction of high yielding crop species for efficient phytoextraction of contaminated soil

Erika Nehnevajova

Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
