Mankind has had the desire to stay young since its existence and used the most unimaginable techniques in order not to age. For a long time, scientists believed that getting older develops autonomously over time. Aging is a process that begins with the gradual decline of physiological organization and disruptions in the functioning of organs and leads to somatic death. However, studies indicate that reducing the aged cell mass may slow down the process, or even correct it by reversing time.

Recent studies provide endless information about how life can be extended. Even the “vampire treatment”, which has existed for centuries, has gained reality with recent publications. Now we see that when we give the blood of young mice to the old, and the blood of the old to the young, the old mice gets younger and the young gets old.

This happens because of the small packets secreted by stem cells. In fact, aging is a learned process. The oldest cell sends a signal to the youngest cell that it must age. Therefore, if you destroy the old cells, you will remain younger. In science, these small vesicles are called exosomes.

 

What is an Exosome?

 

Exosomes are extracellular vesicles or small bubbles that are released from cells. They act as a shuttle from stem cells to other cells genetic information and proteins. They are very small particles, 30-200 nanometers in diameter, about 1/1000 of a cell in size. They allow cell to cell communication, carrying molecules between near and far cells, which are important regulators of intracellular information. They carry information with different functions and purposes that tell the cell how and when to respond. Thus, exosomes released by young stem cells have proven to be very powerful in regulating regenerative processes in the body and aiding rejuvenation. Exosomes are one of the new generation cellular therapies. Exosomes are not cells, they mediate the communication of all cells in our body and play a vital role in their rejuvenation.

The New Horizon of Science

These vesicles, which can be obtained from all body fluids, play an important role in many biological activities such as intercellular communication, signal transmission, genetic material transfer and regulation of immunological response. Exosomes have the ability to repair skin, rejuvenate and reduce inflammation, and these nanovesicles can easily pass through the skin and blood-brain barrier. In addition, exosomes, as they are a natural nanocarrier, enable the design of new generation vaccines in which both the adjuvant and the antigen can be transported.
