Additional file 1: Figure S1. of Ambient particulate matter and microRNAs in extracellular vesicles: a pilot study of older individuals

Morphological characterization of serum extracellular vesicles (EVs). Preparations of EVs were imaged by transmission electron microscopy (TEM). (a) non-labeled EVs, (b) EVs labeled with gold-conjugated anti-CD63 antibody, (c) EVs labeled with gold-conjugated anti-CD81 antibody. Images were taken by a JEOL 1200EX microscope coupled with an AMT 2Â k CCD camera, at the Harvard Medical School Electron Microscopy Core. (DOCX 4627 kb)
