Regarding “Imitation Products” of Our Stem Cell Exosome Nasal Spray

Since the opening of Setagaya Internal Medicine in 2021, we have been offering nasal spray therapy using stem cell exosome culture supernatant. Recently, several stem cell exosome-containing nasal sprays have been advertised online, leading to an increase in inquiries about their differences compared to our products.

Our stem cell exosome-containing culture supernatants (max NFC, CLASS, EXOPure) used at Setagaya Internal Medicine Clinic are also utilized in IV therapies. They are manufactured in facilities approved by Japan’s Ministry of Health, Labor, and Welfare, using a natural cultivation method by experienced specialists without the use of antibiotics, preservatives, or externally added EGF. Impurities and ammonia generated during the culture process are completely removed.

The stem cells used as raw materials are not frozen but are harvested from donors and cultured within 24 hours to produce exosome-containing culture supernatant. (Typically, cells that have been frozen before culturing are partially damaged.)

Currently, the market is flooded with products of varying quality, some of which are reportedly diluted to several times or even hundreds of times the concentration of legitimate products.

The stem cell culture supernatants handled by our clinic are subject to strict safety standards and consistent quality control, ensuring uniformity and high quality throughout the production process. The high concentration of cytokines, which characterizes our super-concentrated stem cell supernatants, is also used in our exosome nasal sprays, ensuring safety and reliability for you and your family.

These nasal sprays are used in the treatment of patients undergoing rehabilitation in wards for brain diseases. Furthermore, a specialist physician with certified expertise conducts an online consultation with each patient before prescribing the most suitable type.

What is Nasal Therapy?

• Nasal therapy involves inhaling stem cell culture supernatant and injecting it into the nasal cavity. This method allows patients to administer the treatment easily at home themselves after receiving counseling from a physician.

Limitations of Traditional Intravenous Infusions

With traditional intravenous infusions, the active ingredients in the culture supernatant cannot pass through the blood-brain barrier (BBB) of the brain’s capillaries.

Advantages of Nasal Administration

Therefore, in cases of brain diseases or functional decline due to aging, and for the treatment of central nervous system disorders such as spinal cord injuries, cervical spondylosis, and cervical spinal canal stenosis, administration through the nose is preferred over intravenous infusions.

As a result, this treatment method is reported to be highly effective in treating central nervous system disorders, including brain diseases, especially in the prevention and early-stage treatment of dementia. This efficacy is achieved because the active ingredients act directly on brain cells by passing through the olfactory bulb via the culture supernatant.

Effects on Hay Fever and Allergic Rhinitis

Additionally, because nasal sprays are administered directly to the nasal mucosa, exosome-containing nasal sprays are emerging as a new treatment option for symptoms such as runny nose, nasal congestion, sneezing, and itchy eyes caused by hay fever.

Hay fever is an allergic reaction triggered by pollen, resulting in symptoms like a runny nose, nasal congestion, sneezing, and itchy eyes. Traditional treatments for hay fever include antihistamines and steroid nasal sprays, but these often come with side effects and may not be effective for all patients.

Exosome-Containing Nasal Sprays as a New Treatment Option

Against this backdrop, nasal sprays utilizing exosomes are gaining attention as a new treatment option. Exosomes are tiny extracellular vesicles that play a crucial role in intercellular communication. They contain various beneficial molecules, including growth factors, neuroprotective factors, and angiogenic factors, which aid in cell regeneration and repair.

Recent research indicates that exosome nasal sprays can potentially improve hay fever symptoms fundamentally by delivering these molecules directly to the nasal mucosa. Specifically, the components within the exosomes act on the immune cells of the nasal mucosa to suppress excessive immune responses that trigger allergic reactions. This suppression helps reduce inflammation and alleviate symptoms. Furthermore, exosomes promote the repair and regeneration of the nasal mucosa, leading to long-term therapeutic effects.

Nasal Spray Treatment Effects for Alzheimer’s Disease Patients

• According to Professor Emeritus Minoru Ueda from Nagoya University, the use of cultured supernatant shows remarkable improvement in patients with Alzheimer’s disease, stroke, atopic dermatitis, rheumatoid arthritis, and hay fever, among other intractable diseases. This cultured supernatant can be produced in liquid or powder form and is capable of mass production. Compared to the costs of stem cell transplantation, this treatment is only 1/100th the price and does not require expensive transplant surgery, being administrable via intravenous infusion, topical application, or nasal inhalation.
• 

This innovative technology, which began large-scale collaborative clinical research with the University of Bergen, Norway, in 2019, possesses the ability to regenerate damaged cells in the body. Additionally, it has shown potential in treating interstitial pneumonia caused by the novel coronavirus and its sequelae, as well as amyotrophic lateral sclerosis (ALS), conditions that previously lacked specific treatments.

Stem Cell Exosome Nasal Administration as a Treatment Option for Post-COVID-19 Symptoms

Stem cell exosome nasal administration is gaining attention as a treatment option for post-COVID-19 symptoms.

Even four weeks after the onset of COVID-19, persistent symptoms, known as post-COVID-19 syndrome, have been reported, such as:

Brain Fog:

A cognitive impairment where it feels like there’s a fog in your mind, making it difficult to remember things.

Respiratory Issues:

Symptoms include cough, shortness of breath, chest pain, and discomfort.

Physical Function Disorders:

These include loss of smell and taste, fatigue, headaches, joint pain, and loss of appetite.

Mental and Cognitive Disorders:

Symptoms include post-traumatic stress disorder (PTSD), memory problems, anxiety, depression, insomnia, and loss of appetite.

The causes of these symptoms may include an overactive inflammatory response (cytokine storm), damage caused by the active virus itself, or an inadequate immune response, but they are not yet fully understood.

As a result, the treatment of post-COVID-19 symptoms can take a long time, and in some cases, symptoms may persist even a year after infection.

Even if the symptoms are mild, there is a possibility that various parts of the body have been damaged, leading to prolonged symptoms.

In Japan, specialized outpatient clinics for post-COVID-19 symptoms are still limited, and no established treatment method has been developed.

Since respiratory and neurological issues are common among post-COVID-19 symptoms, research has shown that the nasal administration of cultured supernatant can be effective.

Cultured supernatant has anti-inflammatory effects and acts as a scavenger of reactive oxygen species, potentially aiding in the repair of damaged cells and the activation of weakened cells.

The effectiveness of exosome nasal therapy for stroke, spinal cord injury,

and cervical spondylosis has gained increasing attention in recent years. Recent studies have reported that stem cell-derived exosomes can help reduce the aftereffects of stroke and spinal cord injuries and enhance rehabilitation outcomes.

The supernatant produced during stem cell culture contains cytokines, such as neuroprotective factors, growth factors, and angiogenesis factors, which activate brain stem cells and promote self-repair. Nasal administration has been shown to be more effective than intravenous delivery, as it allows the exosomes and cytokines to reach the brain quickly and at higher concentrations via the olfactory bulb and trigeminal nerve pathways.

This therapy has led to dramatic recoveries, with some spinal cord injury patients regaining the ability to walk independently within weeks after stem cell therapy. This approach is reported to be more than 10,000 times more effective than intravenous administration.

These advancements offer significant hope for treating stroke, central nervous system disorders, spinal cord injuries, cervical spondylosis, and cervical spinal canal stenosis. Exosomes, small vesicular structures secreted by cells, play a key role in cellular communication and are rich in components that promote the repair of damaged brain tissue. Research suggests that exosomes derived from stem cells may support the regeneration and functional recovery of brain regions affected by stroke.

Originally used to alleviate symptoms of dementia, stem cell supernatant nasal spray treatment is now also gaining attention as a therapy with anti-aging benefits, including improved skin health, hair growth, sexual function, and cognitive enhancement.
