HCC exosomes promote xenograft tumor growth and angiogenesis. (A) Representative examples of mice treated with different types of exosomes. (B) The mice weight overtime. (C) Tumor growth over time. (D and E) Tumors were analyzed by immunohistochemistry analysis for CD31 expression and vascular density (scale bar, 100 µm). **P<0.01. HCC, hepatocellular carcinoma; HCC-ex, exosomes derived from HCC patients; normal-ex, exosomes derived from healthy individuals; CD, cluster of differentiation.
