Exosomes

特許 係属中 Exosomes are cell-derived vesicles that are present in many and perhaps all biological fluids, including blood, urine, and cultured medium of cell cultures.[1][2] The reported diameter of exosomes is between 30 and 100 nm, which is larger than LDL, but much smaller than for example red blood cells. Exosomes are either released from the cell when multivesicular bodies fuse with the plasma membrane or they are released directly from the plasma membrane.
