Separated and visible: cellular structure
Thanks to a new technique that allows them to expand tissue 20-fold before imaging it, MIT researchers used a conventional light microscope to generate high-resolution images of synapses (left) and microtubules (right). In the image at left, presynaptic proteins are labeled in red, and postsynaptic proteins are labeled in blue. Each blue-red “sandwich” represents a synapse. Credit: MIT/Nature Methods.
