exosome - (pronounced) (EK-soh-some) A tiny sac-like structure formed within a cell that contains some of the cell's proteins, DNA, and RNA. Exosomes are released into the blood by many types of cells, including cancer cells, and travel through the blood to other parts of the body. They are able to transfer the proteins, DNA and RNA they contain to other cells. Exosomes may play a role in the spread of cancer and may also stop immune cells from killing cancer cells. They are studied in the laboratory to develop new ways of diagnosing and treating cancer, including preventing cancer cells from spreading throughout the body
