Virginia Tech scientists at the Fralin Biomedical Research Institute have developed a novel way to isolate exosomes from cow’s milk. The research team, Jane Jourdan (left), Spencer Marsh, Kevin Pridham, and Rob Gourdie, visited Donnie Montgomery (right) of Homestead Creamery, which has provided the scientists with unpasteurized milk samples for experimentation. The researchers’ purification protocol was published this month in Nanotheranostics. (Photo: Whitney Slightham for Virginia Tech)
