Exosomes DC-EX
Exosomes today represent a promising direction for the treatment, prevention, and rehabilitation of various diseases.

DC-EX exosomes have the therapeutic potential of mesenchymal stem cells, are easy to obtain, and can be stored for up to 2 years.

The fundamental basis for the therapeutic effects of DC-EX exosomes lies in their ability to transfer biological information—in the form of cytokines, peptides, and RNA—from stem cells to damaged cells.

DC-EX exosomes have theoretical advantages over intact MMSCs as a drug in the field of regenerative medicine.

Exosomes
Description of exosomes
Exosomes are microscopic extracellular vesicles secreted into the intercellular space by cells of various tissues. Exosomes contain signaling substances that "tell" neighboring cells what and when to do.

Exosomes derived from human mesenchymal stem cells from bone marrow are the active ingredient in DC-Ex.

Exosomes provide:

• Epigenetic reprogramming (activates reparative cycle signaling pathways). Thus, cells reorient themselves toward the process of restoring the microenvironment.

• Exosomes also affect regional progenitor cells, triggering a cascade of migration and recruitment of other cellular elements and their differentiation. Microcirculation and cellular immunity are restored in tissues. Undesirable inflammatory reactions are blocked.
Exosomes consist of:
1. MicroRNA
2. Growth factors
3. Cytokines (signaling molecules)
4. Peptides
Exosome action:
1. Activation of regeneration
2. Reduction of inflammation, apoptosis (cell death), and fibrosis
3. Angiogenesis (growth of new capillaries)
4. Immunomodulation (stimulation or suppression)
Exosomes
Use of exosomes
1. Revitalization: increased performance; disease prevention; health maintenance; anti-aging therapy.
2. Treatment: diseases of the heart, lungs, brain and nervous system, liver, kidneys, autoimmune diseases, diabetes, infertility.
3. Orthopedics: joint and spine diseases, injuries.
4. Cosmetology: mesotherapy to slow down aging and promote healthy skin.
5. Urology: erectile dysfunction.
6. Dermatology: skin diseases.
7. Surgery: skin damage, burns, frostbite, purulent inflammation, etc.
8. Oncology
Exosomes
Comparison of exosomes with stem cells
The primary effect of donor stem cells is paracrine—that is, the expression of exosomes containing biologically active substances. Thus, donor stem cells exert their effects through exosomes. The use of exosomes from donor multipotent mesenchymal stem cells (MMSCs) can replace or complement the use of MMSCs.

In some cases, these effects have been clearly demonstrated to be as effective as the administration of whole-cell MMSCs. The fundamental basis for the therapeutic effects of exosomes lies in their ability to transfer biological information—in the form of proteins, glycoproteins, lipids, and ribonucleic acids—from stem cells to damaged cells.

Exosomes have theoretical advantages over intact MMSCs as a therapeutic agent and may in the future gain an advantage over whole cells in the field of regenerative medicine.

Exosomes are significantly less expensive than MMSCs. Unlike MMSCs, exosomes can be stored for a long time (up to 24 months).
Exosomes

Exosomes DC-EX -
CD-9 affiliation marker
CD9 is a standard exosome marker recognized internationally. Detection of CD9 confirms that these are genuine exosomes.
Clinical significance: There are products on the market that are sold as "exosomes," but are actually:
  • conditioned medium
  • cellular debris
  • microparticles
Detection of CD9 proves that:
  • these are genuine extracellular vesicles
  • they are not protein supernatants
  • they are not an adulterated product
DC-EX exosomes are a marker of CD-63 affiliation.
CD63 is the second international exosome marker - detection of CD63 indicates compliance with standards.
Interpretation:
  • Only CD9 - possible impurities
  • Only CD63 - possible low concentrations
  • CD9 + CD63 - authentic, high-quality exosomes
Clinical conclusion:
  • Authentic material
  • Minimal impurities
  • Low risk of inflammation
  • High batch-to-batch stability
DC-EX Exosomes – Benefits of High Concentration
  1. Faster onset of anti-inflammatory effect
  2. Accelerated tissue repair
  3. Improved mitochondrial activity
  4. Simultaneous action on multiple symptoms (chronic inflammation, fatigue, nervous system, skin, liver, etc.)

The patient feels the effect even after a single treatment!

  • Most products on the market contain only 10-50 billion exosomes per ml, which is orders of magnitude less.
  • Changing the concentration directly impacts the clinical effect and patient satisfaction.
DC-EX Exosomes – The Benefits of Large Size
NanoSight Analysis (NTA)
The average size of DC-EX exosomes is 136.6 nm—closer to the upper limit (30–150 nm) and indicates a predominance of mature particles.

Advantages of mature particles:
  • contain many growth factors, cytokines, and microRNAs
  • better tissue repair
  • pronounced anti-inflammatory effect
  • high mitochondrial activity
DC-EX Exosomes – The Benefits of Homogeneity
Distribution: A single peak indicates minimal impurities.
If there were exosome contamination:
  • Several peaks
  • Broad tail
  • Size spread
Conclusion: DC-EX product:
  • Highly concentrated
  • Stable
  • Homogeneous

In a clinical setting, the following are important:
  • Concentration
  • Quality
  • Homogeneity
DC-EX Exosomes – Infection Safety
high level of infection safety

comparison with umbilical cord exosomes
Disadvantages of umbilical cord exosomes
  • Increased OncomicroRNA
  • Risk of tumor stimulation
  • Immune hyperstimulation
  • Quality variability
Ethical and production risks
  • Risks for umbilical cord exosome clinics
  • Unpredictable results
  • Exacerbation of chronic diseases
  • Reputational risks
  • Legal risks
Clinical advantages of BM-MSCs
  • Better for chronic inflammation
  • Safer for autoimmune conditions
  • Suitable for anti-aging
  • Stable results
  • Natural mechanism – bone marrow-derived MSCs are programmed for regeneration and restoration. Accordingly, bone marrow-derived MSC exosomes are a natural regenerative mechanism created by nature. Adults lack umbilical cord MSCs.
  • Bone marrow-derived MSC exosomes have a perfectly balanced microRNA ratio: tumor suppressor microRNA ~78%; oncomicroRNA ~22%. This means an ideal balance of suppressive and stimulatory oncomicroRNAs. OncomiRs are essential, but their excess is dangerous. Therefore, bone marrow-derived exosomes carry no oncological risk.
Main components of
exosomes DC-EX - Growth Factors
DC-EX exosomes contain 60 growth factors (GFs). Key GFs and effects:
  • IGF/EGF/PDGF → tissue repair
  • VEGF → angiogenesis
  • HGF → liver repair
  • TGFβ → anti-inflammatory effect
  • IL-10 → anti-inflammatory effect
  • IL-1ra → immunoregulation

It's not "more is better"; it's the balance of GFs that matters. DC-ECGFs in exosomes are maximally balanced.

  • Injections of individual growth factors provide an isolated, rapid, and short-term effect.
  • Injections of DC-EX exosomes provide a combined, long-term effect.

Which microRNAs are considered the most important?
Based on the volume of experimental data and potential therapeutic significance, the following list can be identified:
1. miR-124 — neurogenesis and anti-inflammatory effect.
2. miR-133b — axon growth and neuroplasticity.
3. miR-21 — neuronal protection and regeneration.
4. miR-17-92 — axon and neuron repair.
5. miR-219 — remyelination.
6. miR-146a — inflammation control.
7. miR-132 — formation of new synapses.

DC-EX-BC
It has a targeted biological profile, rather than simply aiming for the maximum concentration of individual molecules:
Growth factors:
FGF-2, EGF, KGF/FGF-7, HGF, IGF-1, PDGF-BB, along with controlled levels of VEGF and, in particular, TGF-β. EGF is supported by a substantial body of evidence regarding epithelial repair and aesthetic dermatology.

Exosome production

There are three main methods for producing exosomes:

  • Differential ultracentrifugation (DUC)
  • Density gradient ultracentrifugation
  • Ultrafiltration

We use our own ultrafiltration method.

During the MMSC cultivation process, exosomes are isolated into a nutrient medium. After MMSC isolation, a solution containing exosomes (supernatant) remains in the cultivation chamber.

The supernatant is then filtered and concentrated (5 or 10 times), and packaged.

DOKAR Laboratory has developed its own exosome production technology—triple filtration and concentration.

We use 0.22 and 0.45 µm filters and dialysis cartridges.

We have created our own exosome concentration system.
