SA: Our paper entitled ‘Blood extracellular vesicles from healthy individuals regulate hematopoietic stem cells as humans age’ was led by Isabelle Grenier-Pleau, who has done a fantastic job of identifying our initial observations that extracellular vesicles from older subjects stimulate haematopoietic stem cells. Isabelle is now entering her first year as a PhD candidate, and now will continue on with this work, teasing out potential mechanisms behind these novel findings.
