It is a highly zoomed-in picture of a mouse lung. The connective tissue (collagen) appears in [blue]. The blood vessels are visible in [purple]. They turned red after treatment with a new drug carrier (lipid nanoparticle) that can deliver drugs or gene therapy agents to the blood vessels of the lung. This technology can be used to deliver drugs to the lung to treat a variety of diseases including cancer.
