Hijacking the Cellular Mail: Exosome Mediated Differentiation of Mesenchymal Stem Cells

Figure 1

Generation and endocytosis of exosomes: (a) a representative TEM image showing the presence of exosomes in our purified samples. Scale bar represents 100 nm. The white arrows in the image point to exosomes. The grids were stained with phosphotungstic acid and hence the background is black. (b) Representative confocal micrograph showing the presence of endocytosed exosomes. White arrows point to the endocytosed exosomes. (c) Confocal micrograph showing the absence of exosomes or nonspecific presence of labeling dye. The scale bar in the confocal micrographs represents 20 μm.
