Fig. 1From: Influence of mesenchymal stem cell-derived extracellular vesicles in vitro and their role in ageingCharacterisation of MSCs from the rat bone marrow at several ages. a One representative fluorescence-activated cell sorting (FACS) assay is shown for old MSCs and young MSCs. The antibody is indicated at the top of each plot and its linked fluorochrome at the bottom. b The plot shows the percentage of positive MSC markers (CD29 and CD90) and negative haematopoietic markers (CD34 and CD45). c Representative images (magnification, × 20) of old and young MSCsBack to article page
