Research on the biology of circulating EVs was supported by an Innovation Grant from the Canadian Cancer Society (no. 702835; JEF), Seed and Team Funding from the Canadian Vascular Network (MH, RSP, JEF), Project Grants from the Canadian Institutes of Health Research (PJT148487 and PJT173489; JEF), an AstraZeneca Impact Challenge Grant (RP and JEF), Canada Foundation for Innovation, John R. Evans Leaders Fund and the Ontario Research Fund. JEF received salary support through a Tier 2 Canada Research Chair in Vascular Cell and Molecular Biology from the Canadian Institutes of Health Research. PVD’s salary was supported by a Postdoctoral Fellowship from the Toronto General Hospital Research Institute. DG’s salary was supported by the Frederick Banting and Charles Best Canada Graduate Scholarship Doctoral Awards from the Canadian Institutes of Health Research, Ted Rogers Education Funding and an Ontario Graduate Scholarship. RW’s salary was supported by a Canada Graduate Scholarship from the Canadian Institutes of Health Research. None of the funders were involved in the design of the study, the collection, analysis and interpretation of data, or writing the report and did not impose any restrictions regarding the publication of the report.
