Exosomes – ERECTUSXOME (TM) FAQ

What are Exosomes?

Exosomes are small structures secreted by most cell types in our bodies that facilitate important functions. They have the ability to transfer DNA, RNA, and proteins to other cells, thereby altering the function of the targeted cells. Exosomes are secreted by most cell types and contribute to functions including tissue repair, neural communication.

The history of Exosomes:

The first documentation of the word ‘exosome’ was in 1987 but researchers discovered these small vesicles being secreted from immature red blood cells called reticulocytes in 1983. They were thought of as little more than mobile trash cans whose job was to discard unwanted cellular components. There wasn’t much research done on exosomes until recently where researchers have started to recognize the medical potential of these cellular vehicles.

Just a trash can or something more?

After an almost 20 year gap of little research done on exosomes, studies started coming out that produced surprising findings. Subsequent research found that exosomes play an active part in cellular communication and instead of just disposing of waste they can carry proteins, RNA, growth factors and functional immune agents. Because of their physical structure and their ability to shuttle multiple products they can target cells that are near or far via blood channels.

Research being done today?

The explosion of exosome research has shown the great potential in medical applications. Regenerative medicine is a key area for the use of exosomes because of the growth factors they can shuttle. Growth factors are proteins that stimulate the growth of tissue and exosomes can deliver hundreds of these growth factors across a long distance. There is also promising areas of study in cancer research regarding exosomes and the ability to deliver antitumor responses which can initiate apoptosis (death of a cell) of these cancer cells. There is still more research to be done on exosomes but they are a bright new area of study in stem cell research, cellular health, and regenerative medicine.
