Ex-RNA in exosomes?

It’s fun to read about things that were part of my life and kept going. Like exosomes. My little review from 2005 still gets a lot of hits due to the current popularity of exosomes. I follow what exosome people do in their Facebook page. It was a cool project to do. Lots of ultracentrifugations. Good times. What do you think about little vesicles and exosomes? Will they be the next diagnostic breakthrough?
