A team of researchers led by Stavros Lamvardas of the University of California, San Francisco used the Advanced Light Source’s National Center for X-ray Tomography, led by Carolyn Larabell and Mark LeGros, to help understand the unique epigenetic mechanism by which each olfactory nerve cell sequesters all but a single receptor gene.
