A Tissue Transparency Technique Lets Us Examine Organs Like Never Before

German researchers have created 3D technology to view every micrometer of an entire human organ. The unprecedented imaging technique called SHANEL allows for scientists to label tissues on a deep level and clear large organs such as the brain and kidney. Using deep learning, SHANEL analyzes cellular and molecular architecture that takes mere hours. It requires removing pigment and fats from organs and a large specialized microscope to take photos. In a recent issue of  Cell,the method ’s developers explain that the technology is still fairly conceptual and needs further research for it to fully come to life. The researchers studied the challenges typically presented when analyzing human organs. It ’s difficult to deeply examine antibodies and other large molecules lodged deep into tissue due to the accumulation of insoluble macromolecules. To rectify this, the researchers used CHAPS, a zwitterionic detergent that creates tiny holes in the organs, allowing the tissue to absorb a solution tha t safely makes it transparent. They also collaborated with biotech company Miltenyi Biotec to create a fluorescent microscope that can image large parts of tissue. With those images generated from the microscope, the researchers were able to identify and map millions of cells in just a few hours. “It’s a task that would take 100 years by hand, and now takes hours,” saidAli Ert ürk, the senior author of the study. Understanding how chemically rendering organs transparent im...
