nuclear speckles in renal cancer (IMAGE) Cold Spring Harbor Laboratory Caption CSHL Assistant Professor Katherine Alexander and colleagues at the University of Pennsylvania have identified two different patterns of cellular structures known as nuclear speckles (red) in the most common form of renal cancer. They’ve also spotted a possible connection between these patterns and patient survival rates. Their work is published in Nature Cell Biology.
