Ferroptosis plays a crucial role in lung cell damage caused by ventilation stretch.

Mechanical ventilation is an essential respiratory support in acute respiratory distress syndrome and intensive care cases. However, it is possible to cause ventilator-induced lung damage (VILI). In this work, we used a microfluidic device to provide a mechanical ventilation with cyclic stretch (30% total area change rate and 15 cycles per min) and oxygen (air) flux applied by a controlled pressured airflow.

Microfluidic-to-macrofluidic: A simple model of atherosclerosis induced by fluidic stimulation.

Atherosclerosis is the narrowing of the arteries due to the formation of fatty plaques, which is the main cause of myocardial infarction and stroke. It is important to develop an model that can combine multiple-type cell co-culture, vessel wall-like structure, and fluid condition to simulate the processes of atherosclerosis. Herein, we used a simple microfluidic chip made of three polydimethylsiloxane layers to co-culture endothelial and smooth muscle cells in a flat rectangular microchannel.
