Non-Invasive Visualization of Nailbed Microvascular Morphology in Mice Using Capillaroscopy.

Summary: Doctors often look at the tiny blood vessels under human fingernails to check for diseases like diabetes or heart problems. But doing this in lab mice is usually hard, expensive, or requires surgery. This new study shares a simple, cheap, and pain-free way to look at the tiny blood vessels in the toes of mice using a special camera. This will help scientists study diseases and test new medicines much more easily!
