Extended Data Fig. 2: Characterization of size distribution and morphology of exosomes from the 14 cell lines.
a, Representative profiles of size distribution of exosomes determined by nanoparticle tracking analysis (NTA), mode of the size distribution is indicated in the figure. b, Quantification of the mode from NTA analyses. Bar graph shows mean ± s.e.m, individual data points refer to three biological replicates for each cell line, dashed line at 100 nm. c, Transmission electron microscopy of exosomes from the 14 cell lines, scale bar = 100 nm, results from one-two replicates per cell type. d, Gating strategy used for flow cytometric analysis of beads-bound exosomes throughout the manuscript.
