As its name indicates, elastin confers elasticity. Elastin fibers are at least five times stretchier than rubber bands of the same size. Tissues that expand, such as blood vessels and lungs, need to be both strong and elastic, so they contain both collagen (another ECM protein) and elastin. In this photo, the elastin-rich ECM is colored grayish brown and is most visible at the bottom of the photo. The curved red structures near the top of the image are red blood cells.Tom Deerinck, National Center for Microscopy and Imaging Research (NCMIR)Mark Ellisman and Tom Deerinck, National Center for Microscopy and Imaging ResearchPhotograph
