Understanding gene expression within the body has been a boon for 21st century biology and therapeutics, but most discoveries that use these technologies only focus on one organ or one small area of tissue. At the University of Chicago's Pritzker School of Molecular Engineering (UChicago PME), Assoc. Prof. Nicolas Chevrier's group has developed a new system to understand how diseases affect molecules, cells, tissues, and organs across the whole body—a major goal of both scientists and physicians. The interdisciplinary work was led by Maggie Clevenger, a staff scientist in the lab, and involved several industrial and academic collaborators.
