We are interested in extracellular vesicles, particularly exosomes—a type of extracellular vesicles released after the fusion of multivesicular endosomes and the cell surface membrane. Because extracellular vesicles encapsulate intracellular small and macromolecules, they can mirror the intracellular states of cells at the molecular levels. Further, recent data suggest these vesicles can not only play roles in extracellular space but also serve as intercellular messengers under certain conditions. To understand how these vesicles are generated and how their release can modulate the cellular states of the recipient cells, we currently probe their biogenesis and roles in epithelial growth.
