Cell Morphology and Intracellular Ionic Homeostasis explored with a Multimodal Approach combining Epifluorescence and Digital Holographic Microscopy

Pierre Magistretti, Pierre Marquet, Christian Depeursinge, Jonas Kühn, Nicolas Pavillon, Pascal Jourdain, Daniel Boss, Aleksandr Benke

The authors have developed a live-cell multimodality microscope combining epifluorescence with digital holographic microscopy; it has been implemented with a decoupling procedure allowing to separately measure from the quantitative phase important cell par ...

A New Lock-step Mechanism of Matrix Remodelling Based on Subcellular Contractile Events

Boris Hinz, Jean-Jacques Meister, Lara Buscemi Estefanell, Lysianne Follonier Castella

Myofibroblasts promote tissue contractures during fibrotic diseases. To understand how spontaneous changes in the intracellular calcium concentration, Ca2+, contribute to myofibroblast contraction, we analysed both Ca2+ and subcellular contractio ...

A Ca2+ ion selective electrode biosensor in microfluidics to monitor hepatocyte’s activities

Philippe Renaud, Harald Van Lintel, Robert Meissner

Ca2+ plays a crucial role in cell communication. For example, periodical changes in Ca2+ concentration act as cell sig- nals. Intracellular Ca2+ signals have been measured by Ca2+ sensitive fluorescent dye [1]. In this study, extracellular Ca2+ variation w ...

Indo-1 derivatives for local calcium sensing

Kai Johnsson, Cindy Fellay, Annina Aebischer

The role of calcium in signal transduction relies on the precise spatial and temporal control of its concentration. The existing means to detect fluctuations in Ca2+ concentrations with adequate temporal and spatial resolution are limited. We introduce her ...

Investigation of novel calcium-related events as suspected contributors to neurodegeneration

Calcium regulates neuronal signaling and viability through a vast range of cellular and molecular mechanisms. However, many details of these mechanisms still remain to be elucidated. It is believed that calcium-related pathways may comprise promising thera ...
