What are exosomes?
Every cell in our body contains a structure called membrane vesicles, which facilitate intercellular communication and transport of proteins and molecules that regulate the various functions of our body. One such class of vesicles consists of exosomes, which are nanovesicles ranging from 30 to 100 mm in diameter, and are found on the surface of different types of cells, including normal and tumor cells.
Previously, exosomes were only known for their waste disposal abilities, as in the removal of unnecessary proteins in cells. However, recent research has explored the potentials of exosomes in various uncharted uses, such as cancer diagnosis and therapy, targeted administration of drugs, and immune therapy.
What are the benefits?
For our purposes, we are interested in the use of exosomes as an immune booster and therapeutic agent to aid in anti-aging therapy and post-cancer recovery treatments.
The main process of using exosomes for therapeutic purposes involves the introduction of exosomes from a host cell to a target cell, by which the exosomes, with their complex composition of proteins and genetic materials, affect the processes of the target cell and nearby cells, as a result of which they induce changes in the functions and behavior of said cells. This way, exosomes can be used to regulate immune responses of cells, which are crucial in combating the degenerative effects of certain diseases and processes, such as cancer and cancer radiation treatments.
Through this process, exosomes can also trigger cell regeneration, which aid in the replacement of damaged tissues, and in the prevention of their further loss or decay. As such, exosomes are useful in addressing the external and internal adverse effects of aging.

How it's done
The procedure is commenced with the extraction of blood from the patient. The blood sample is then processed to harvest exosomes, which will undergo laboratory processing and culture for one week.
Afterwards, the exosomes are ready for introduction to the targeted area via intravenous infusion. Patients can expect the procedure to last for 2 hours.
