Emerging Role for Exosomes in the Progress of Stem Cell Research.

Exosomes are small secretory vesicles that are involved in intercellular communication. Exosomes are secreted by many types of cells and exert important functions in plasma-membrane exchange as well as the transport of bioactive substances, such as proteins, messenger ribonucleic acids (mRNAs), micro ribonucleic acids (miRNAs) and organelles. Exosomes may regulate physiological processes by altering gene regulatory networks or epigenetic recombination.
