image: A "lung-on-a-chip" microdevice for drug and toxin testing recapitulates organ-level functions and breathing movements of the human lung. Fluorescent dyes have been perfused through linear microengineered channels that carry air to lung air sac cells, culture medium to blood capillary cells, and vacuum to drive breathing movements. This image relates to an article that appeared in the June 25, 2010, issue of Science, published by AAAS. The study, by Dr. Dan Huh of the Wyss Institute for Biologically Inspired Engineering at Harvard University in Boston, Mass., and colleagues, is titled, "Reconstituting Organ-Level Lung Functions on a Chip." view more
