Caption: Exosomes. Coloured scanning electron micrograph (SEM) of a cultured 293T cell releasing large numbers of exosomes. Exosomes are vesicles that bud from the surface of a cell. They facilitate intercellular communication by transmitting macromolecules between cells. They can contribute to the development of many diseases, for example viruses use them to manipulate nearby uninfected cells and to suppress the immune system. Exosomes may also be useful vectors for drug delivery, especially patient-derived exosomes that wouldn't cause any adverse reaction in the host. Magnification x 7000 at 10cm wide.
