Human microvasculature-on-a chip: anti-neovasculogenic effect of nintedanib in vitro

Angiogenesis Soheila Zeinali, Colette A Bichsel, Nina Hobi, Manuela Funke, Thomas M Marti, Ralph A Schmid, Olivier T Guenat, Thomas Geiser Abstract Idiopathic pulmonary fibrosis is characterized by a progressive scarring and stiffening of the peripheral lung tissue that decreases lung function. Over the course of the disease, the lung microvasculature undergoes extensive remodeling. There

Incorporating mechanical strain in organs-on-a-chip: Lung and skin

Biomicrofluidics Olivier T. Guenat & François Berthiaume Abstract In the last decade, the advent of microfabrication and microfluidics and an increased interest in cellular mechanobiology have triggered the development of novel microfluidic-based platforms. They aim to incorporate the mechanical strain environment that acts upon tissues and in-vivo barriers of the human body. This article reviews

In vitro-ex vivo model systems for nanosafety assessment

European Journal of Nanomedicine Peter Wick, Savvina Chortarea, Olivier T. Guenat, Matthias Roesslein, Janick D. Stucki, Stephanie Hirn, Alke Petri-Fink & Barbara Rothen-Rutishauser Abstract Engineered nanomaterials have unique and novel properties enabling wide-ranging new applications in nearly all fields of research. As these new properties have raised concerns about potential adverse effects for the environment

A lung-on-a-chip array with an integrated bio-inspired respiration mechanism

Lab on a Chip Andreas O. Stucki, Janick D. Stucki, Sean R. R. Hall, Marcel Felder, Yves Mermoud, Ralph A. Schmid, Thomas Geiser &  Olivier T. Guenat Abstract We report a lung-on-a-chip array that mimics the pulmonary parenchymal environment, including the thin alveolar barrier and the three-dimensional cyclic strain induced by breathing movements. The micro-diaphragm
