A versatile assay for monitoring in vivo-like transendothelial migration of neutrophils

Abstract

Spatiotemporal analysis of the inflammatory response has been limited by the difficulties of in vivo imaging and reconstitution of inflammation in vitro. Here, we present a novel method for establishing in vivo-like inflammatory models in a microfluidic device and quantitatively measuring the three-dimensional transmigration of neutrophils during the inflammatory process. This enabled us to concurrently characterize transendothelial migration behaviors of neutrophils under the influence of various inflammatory stimuli.
