Regenerative medicine is currently undergoing a major transformation.
Up until now, regenerative medicine has focused on "transplanting stem cells."
However, in the fields of longevity research and biotechnology worldwide, the focus is shifting from "the cells themselves" to the "information" that cells contain.
At its core are "exosomes."
Exosomes are tiny extracellular vesicles secreted by cells, containing numerous bioactive substances such as microRNAs, proteins, and growth factors.
In recent years, it has been suggested that these exosomes are the "information transmission capsules" that govern intercellular communication.
And now, what is attracting particular attention from research institutions around the world and in the field of longevity is "exosomes derived from young cells."
“Is "youth" transmitted as information?
The changes that occur in the body due to aging are not simply a decrease in the number of cells.
Recent aging research has emphasized the importance of a phenomenon called "SASP (Senescence-Associated Secretory Phenotype)," in which senescent cells release inflammatory signals to their surroundings.
Senescent cells are,
- chronic inflammation
- Decreased tissue repair capacity
- Mitochondrial dysfunction
- Collagen reduction
- vascular aging
It is thought to be involved in various processes, and it is suggested that "information from aged cells" may be transmitted to the surrounding area.
Conversely, this means that if we can deliver "information from young cells," we may be able to change the aging environment.
This is where exosomes extracted from young-born stem cells are attracting attention.
microRNA contained in exosomes
One of the most important aspects of exosome research is "microRNA."
microRNAs are extremely small RNA molecules that control gene expression and are deeply involved in cell proliferation, inflammation, regeneration, and aging control.
Currently,
- Inflammation suppression
- angiogenesis
- Collagen production
- tissue repair
- Oxidative stress control
Numerous microRNAs involved in various processes have been identified.
In particular, exosomes derived from young cells have been reported to have different microRNA profiles than those of senescent cells, and the possibility of delivering "youthful information" to cells is being studied.
In other words, exosomes are not just nutrients, but are thought to carry "cellular design information."
Longevity healthcare is attracting attention from the world's wealthy.
In recent years, the "Longevity" industry has been expanding rapidly, particularly in the United States.
Especially in Silicon Valley, the Middle East, Hong Kong, and Singapore,
- Biological age analysis
- NAD+ therapy
- Epigenetic testing
- stem cell research
- Exosome research
Investment in this area is accelerating.
The underlying idea is that aging is not an unavoidable phenomenon, but rather a process that can be controlled.
Current longevity research focuses more on "lifespan" itself than on the subject matter itself.
- healthy life expectancy
- Cognitive function
- maintain vitality
- Inflammation control
- conditioning
Interest in this is growing.
In this context, exosomes are beginning to attract global attention as a "next-generation conditioning medicine."
“"Intravenous therapy" is moving to the next stage.
Conventional intravenous therapy,
- vitamin
- mineral
- Antioxidant components
- amino acid
These were the main focus.
However, in the field of regenerative medicine, new approaches that utilize "cell-derived information" are currently being researched.
Exosomes in particular are
- Do not transplant cells
- minimally invasive
- Specialized in information transmission
- Utilizing intercellular signals
Due to these characteristics, it is expected to represent a new direction in regenerative medicine.
Of course, many areas are still in the research stage, and careful discussion is needed regarding quality control, safety, and standardization.
On the other hand, the idea of "improving the communication environment between cells" rather than "replacing the cells themselves" may become an important theme in future medicine.
Regenerative medicine is moving towards "information medicine."
Regenerative medicine may evolve from simple cell therapy into "information medicine."
Cells do not exist in isolation.
I constantly exchange information with my surroundings to maintain overall physical balance.
Exosome research is also an attempt to decipher this "communication between cells."
Can information from young cells really be transplanted?
Can aging be controlled at the information level?
Exosome and microRNA research is quietly evolving towards its future.
