What is exocrine

Exosomes refer to small membrane vesicles (30-150nm) containing
complex RNA and proteins. In 1983, exosomes were first discovered in
sheep reticulocytes. In 1987, Johnstone named it "exosome". A variety
of cells can secrete exosomes under normal and pathological conditions,
and exosomes naturally exist in body fluids, including blood, saliva, urine,
cerebrospinal fluid, and milk. It is mainly derived from the multivesicular
bodies formed by the invagination of intracellular lysosomal particles,
which are released into the extracellular matrix after the fusion of the
multivesicular outer membrane and the cell membrane. Exosomes are
currently viewed as specifically secreted membrane vesicles involved in
intercellular communication, and there is growing interest in the study of
exosomes, both to study their function and to understand how they can be
used in the development of minimally invasive diagnostics.
