Exosomes are microscopic sacs, also called extracellular vesicles, that cells excrete and also absorb. They can transfer materials such as DNA, RNA, and proteins, which means they are excellent messengers that affect the function of recipient cells.
In terms of Innovative medicine, they can be highly effective at carrying stem-cell-based treatments directly into the target cells. In addition to treating signs of aging by promoting tissue repair, they can also be useful for the treatment of conditions ranging from orthopedic injuries to heart disease to respiratory disorders. Typically exosomes are administered by injection or intravenously.
