Exosomes Vital for Heart Repair
Kerry Grens | May 6, 2014
Reparations after a heart attack in mice depend not on stem cells, but on the exosomes they secrete.
Kerry Grens | Mar 1, 2014
Unlike the usual smooth, spherical shape of exosomes, glioblastoma-derived exosomes appear to have long nanofilaments protruding from their surfaces.

These small membrane vesicles do much more than clean up a cell’s trash—they also carry signals to distant parts of the body, where they can impact multiple dimensions of cellular life.
Clotilde ThÃ©ry, Clotilde ThÃ©ry | Jul 1, 2011
Exosomes are small membrane vesicles secreted by most cell types. Internal vesicles form by the inward budding of cellular compartments known as multivesicular endosomes (MVE).
