Endocytic hucMSC-EMVs in MC 3 T 3-E1 cells. EMVs were not endocytosed into the cytoplasm at 0 hr, but they were endocytosed into the cytoplasm at 12, 24, and 48 hr, and EMV endocytosis increased significantly over time, increasing aggregation along the nuclear membrane at 24 and 48 hr (scale bar: 50 μm).
