Abstract
Cells are communicating each other by exchanging their nucleic acids, proteins, metabolites, lipids etc, many of them are carried by extracellular vesicles (EVs) including exosomes and microvesicles. Thus, exosomes are rich sources of information regarding the host cells that released them. In this review, I introduce a brief history of exosome researches and discuss about what are needed at the moment to establish the “exosome medicine”.
