At Exosome Diagnostics, we are focused on developing and commercializing revolutionary, biofluid-based diagnostics to deliver personalized precision healthcare that improves lives. Our diagnostics harness the power of exosomes, important cell messengers carried within biofluids, such as serum, plasma, urine, cerebrospinal fluid and saliva, that contain RNA, DNA and proteins from their cell of origin. Our Chief Scientific Officer and Founding Scientist, Johan Skog, PhD, while at Massachusetts General Hospital, was the first to demonstrate that molecular mutations in a tumor could be detected in RNA extracted from exosomes and that this information could be used diagnostically.
