Exosomes are biomolecules, ranging from 40nm to 150nm. They are released by every cell type in the body. As we now know, exosomes are key mediators of cell-to-cell communication. Each exosome delivers a specific cargo of lipids, proteins, and nucleic acids that are connected to the cell of origin. Thanks to that we can treat exosomes as an early cancer signal (when they are secreted by the cancer cells) or as a potent driver of healing and regenerative signal – when exosomes are secreted by stem cells.
A lot of clinical trials with exosomes are underway. Most of them are connected with one of two issues: early diagnosis and regenerative signaling.
Exosomes are found in all body fluids and play an important role in carrying messages from one cell to the other. This communication works in a target-specific manner, with the recipient cell being proximal or distant to the sender cell.
