Figure Lengend Snippet: (A) Electron microscopic image of negative-stained EVs. The inset shows a magnification of the boxed EV. (B) Size distribution of vesicles in EV preparations measured by image software (n = 110). (C) (F) (I) (L) GPC5-immunostained EVs (red) stained for Rab11 (green) (C), FGFR1 (green) (F), CD63 (green) (I), and ARF6 (green) (L). In (I) and (L), an Alexa Fluor 647- conjugated anti-GPC5 antibody was used to detect of GPC5-ositive particles. (D) (G) (J) (M) Line scan determination of the red bars in (C), (F), (I), and (L): GPC5 (red), others (green). (E) (H) (K) (N) Distribution of GPC5-positive particles identified by scan determinations in (D), (G), (J), and (M). n = 1,516, (E), 630 (H), 573 (K), and 835 (N). Scale bars: (A), 500 nm; (C), (F), (I), (L), 2 μm.
