Frequently Asked Questions

What are Mesenchymal Stem Cells (MSCs)

Mesenchymal Stem Cells (MSCs) are undifferentiated cells capable of developing into diverse cell lineages. These cells maintain the capacity for self-renewal and are highly responsive to their surrounding environment. Upon receiving specific signals, they commit to differentiation pathways, transforming into specialized cells like skin, muscle, cartilage, tendon, bone, or red blood cells. Augmenting the availability of stem cells at a site of injury or damage can significantly promote optimal tissue regeneration by ensuring an ample supply of cells for repair.

What makes mesenchymal stem cells (MSCs) useful in a clinical setting?

Mesenchymal stem cells (MSCs) are increasingly utilized in treating a range of diseases due to their remarkable properties. These include self-renewal (the ability to create more stem cells), differentiation (the process of maturing into specialized cells with distinct form and function; for example, an MSC can develop into various cell types), anti-inflammatory effects (reducing harmful inflammation), and immunomodulation (regulating the immune system). Immunomodulation is particularly important, as MSCs can both stimulate a weak immune response and dampen an overactive one, potentially preventing the autoimmune reactions seen in many disorders. The anti-inflammatory capabilities of MSCs are crucial, as while inflammation is a natural defense mechanism, chronic or excessive inflammation can damage the body.

Extensive research, including both in-vitro (laboratory-based) and in-vivo (within a living organism) studies, has supported the safety and efficacy of MSC therapy and continues to elucidate the underlying mechanisms. This research highlights the diverse capabilities of MSCs, enabling their use in a variety of clinical settings for numerous degenerative conditions.

Emerging evidence suggests that umbilical cord tissue-derived MSCs (UC-MSCs) may possess greater potency compared to MSCs from other sources, potentially leading to enhanced clinical effectiveness.

Are there ethical issues involving this form of stem cell therapy?

Adult mesenchymal stem cells (MSCs) do not raise the same ethical concerns as fetal and embryonic stem cells. Both the Catholic Church and the Southern Baptist Convention have endorsed the research and therapeutic use of adult stem cells as an ethically acceptable alternative.

Why use umbilical cord tissue-derived mesenchymal stem cells (UC-MSCs)?

Advantages of Umbilical Cord Tissue-Derived Mesenchymal Stem Cells (UC-MSCs)

Umbilical cord tissue-derived mesenchymal stem cells (UC-MSCs) offer several advantages over other sources of MSCs, such as bone marrow-derived MSCs (BM-MSCs) and adipose-derived stem cells (ASCs):

  • Superior Proliferation: UC-MSCs exhibit a significantly higher proliferation rate in vitro (in a laboratory setting) compared to BM-MSCs and ASCs. This allows for more efficient expansion to obtain the large cell numbers needed for therapeutic applications.

  • Non-Invasive Harvesting: The collection of UC-MSCs is non-invasive. The cells are obtained from ethically donated umbilical cord tissue after birth, a process that poses no risk or discomfort to either the mother or the newborn. This contrasts with BM-MSC harvesting, which requires a bone marrow aspiration, and ASC harvesting, which typically involves liposuction.

  • Enhanced Secretion of Beneficial Factors: UC-MSCs secrete a variety of growth factors, cytokines, and chemokines. These secreted factors play a crucial role in tissue repair, reducing inflammation, and modulating the immune system.

  • Differentiation Potential: Like other MSCs, UC-MSCs can differentiate into various cell types, contributing to tissue regeneration.

  • Upregulated Genes: Research indicates that certain genes associated with cell proliferation (e.g., EGF), signaling pathways involved in cell survival and growth (e.g., PI3K-NFkB pathway via TEK), and neurogenesis (e.g., RTN1, NPPB, NRP2) are upregulated (have increased activity) in UC-MSCs compared to BM-MSCs. This suggests a potentially greater capacity for tissue repair and regeneration.

Is regenerative medicine being used to treat patients yet?

Yes! In recent years, several regenerative medicine treatments have been introduced into clinical practice for pain management and orthopedic care. These treatments utilize adult stem cells, making them non-controversial. The available procedures include:

  • Platelet-Rich Plasma (PRP) Therapy
  • Mesenchymal Stem Cell-Rich Injections
  • Bone Marrow-Derived Stem Cell Injections
  • Fat-Derived Stem Cell Injections

Regenerative medicine may offer benefits for various medical conditions, including:

    • Joint arthritis
    • Tennis elbow (lateral epicondylitis)
    • Golfer’s elbow (medial epicondylitis)
    • Rotator cuff tendonitis
    • Ligament sprains
    • Fractures
    • Tendon injuries
    • Cartilage defects
    • COPD
    • Kidney failure
    • Stroke
    • Multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS)
    • Dementia
    • Erectile dysfunction
    • Heart failure
    • Diabetes
    • Diabetic neuropathy
Is there any chance my body rejects mesenchymal stem cells (MSCs)?

MSCs possess immunosuppressive properties, reducing the likelihood of immune rejection compared to other foreign cells. Umbilical cord tissue-derived MSCs (UC-MSCs) are particularly immune-privileged, meaning they are universally accepted by the recipient’s body with virtually no risk of rejection. This is because UC-MSCs are essentially “new” and haven’t been “claimed” by a specific immune system. Unlike organ transplantation, UC-MSC therapy doesn’t require blood products or HLA matching.

Does insurance cover regenerative medicine therapy?

Regenerative medicine procedures are generally not covered by insurance. While some surgical applications may have billing codes, most treatments are considered out-of-pocket expenses.

How much do regenerative medcine treatments cost?

The price range for regenerative medicine injections is broad, typically between $1,500 and $7,500.

Who is a Candidate for Stem Cell Therapy?

Our protocol is designed to significantly reduce chronic low-grade inflammation over an extended period. Stem cells possess a unique ability to target areas of inflammation in the body. Research indicates that they can regenerate damaged or diseased tissues, decrease inflammation, and regulate the immune system—contributing to improved health and overall quality of life.

Studies suggest that mesenchymal stem cells (MSCs) may have a positive impact on various conditions, including:

  • ALS
  • Alzheimer’s disease
  • Autoimmune disorders
  • COPD and other degenerative/inflammatory lung diseases
  • COVID-19 (acute and long-haul)
  • Chronic inflammation
  • Crohn’s disease
  • Type 1 diabetes
  • Heart failure and heart disease
  • Kidney disease
  • Liver disease
  • Lupus
  • Lyme disease
  • Multiple sclerosis
  • Degenerative neurological conditions
  • Neuropathy
  • Parkinson’s disease
  • Reflex Sympathetic Dystrophy (RSD) / Complex Regional Pain Syndrome (CRPS)
  • Rheumatoid arthritis
  • Spinal cord injuries
  • Stroke (ischemic and hemiplegic)
  • Traumatic brain injury (TBI)
How many sessions will I need?

Our protocol aims for long-term stabilization of the condition with a single treatment. Follow-up treatments are not required. While some patients choose to return for additional treatments, typically seeking further improvement, generally one treatment is sufficient for most degenerative conditions.

Will the treatment be painful?

Patients generally report minimal discomfort during treatment, often describing the experience as painless. 

When will I start seeing results?

While individual responses vary, many study participants report noticeable improvements within 1-3 months after treatment. These improvements are evidenced by reduced systemic inflammation and increased vitality, as measured by follow-up questionnaires. Some patients report improvements in symptoms and quality of life even sooner, within the first few days post-treatment.

Do stem cells get trapped in the lungs? (Pulmonary first pass effect)

Umbilical cord-derived mesenchymal stem cells (UC-MSCs) are particularly effective for systemic delivery via intravenous infusion. Their optimal size (17-19 micrometers) allows for efficient passage through the circulatory system, including the lungs. Although a portion of MSCs may initially be trapped in the lungs (a phenomenon known as the pulmonary first-pass effect), this does not negate their therapeutic benefits. MSCs possess a remarkable homing ability – they can actively migrate to damaged tissues. Even while temporarily in the lungs, MSCs exert beneficial paracrine effects: they secrete growth factors and other molecules that reduce inflammation and stimulate tissue repair. Advances in research are continually enhancing the delivery and efficacy of MSCs for regenerative therapies.

Can stem cells help prevent aging?

Potential of Stem Cells in Anti-Aging and Rejuvenation

Current research suggests that stem cell therapies may have the potential to mitigate some effects of aging and improve overall healthspan. Stem cells, particularly mesenchymal stem cells (MSCs), possess properties that could contribute to this, including their ability to:

  • Repair damaged tissues: Stem cells can differentiate into various cell types, potentially replacing aged or damaged cells.
  • Reduce inflammation: Chronic inflammation is a key contributor to age-related decline, and MSCs have anti-inflammatory effects.
  • Modulate the immune system: MSCs can help regulate immune function, which often declines with age.
  • Homing Capability: Stem cells can migrate to sites of damage or inflammation.

The concept of a “protective shield” created by stem cells and anti-aging genes is a simplified representation of these complex biological processes. While a complete reversal of aging is not currently feasible, studies suggest that stem cell interventions, potentially in combination with therapies targeting aging-related genes, could contribute to a healthier and potentially longer lifespan. It’s crucial to understand that this is an area of ongoing research, and many claims about “anti-aging” stem cell treatments are not yet supported by robust clinical evidence.

Potential Benefits of Stem Cell Therapy (Observed and Reported):

Some reported benefits of stem cell therapies, particularly in the context of age-related decline, include:

  • Increased energy and vitality
  • Improved physical capacity and endurance
  • Improved hair quality and thickness
  • Enhanced libido
  • Pain reduction
  • Increased strength, balance, and overall mobility
  • Enhanced immune function
  • Overall improvement in quality of life
  • Reduced inflammatory markers
Can MSCs cause Graft vs. Host Disease?

Mesenchymal stem cells (MSCs) are not a cause of graft-versus-host disease (GVHD); in fact, they are being investigated as a potential treatment for this condition. GVHD is a serious complication that can occur after allogeneic hematopoietic stem cell transplantation (typically bone marrow or cord blood transplants), where the donor’s immune cells (T-cells) attack the recipient’s tissues.

MSCs possess immunomodulatory properties that make them promising candidates for GVHD therapy. They achieve this through several mechanisms, including:

  • Secretion of bioactive molecules: MSCs release proteins, peptides, and hormones that can suppress the immune response.
  • Mitochondrial transfer: MSCs can transfer mitochondria (the energy-producing components of cells) to damaged cells, potentially aiding in tissue repair.
  • Exosome and microvesicle release: MSCs release small vesicles containing RNA and other molecules that can influence the behavior of recipient cells, including immune cells.

While many studies suggest that MSC therapy can be beneficial for both acute and chronic GVHD, more extensive, large-scale, randomized controlled trials are needed to definitively confirm these findings and establish optimal treatment protocols.

It is important to clarify a distinction: although MSCs can modulate the activity of immune cells like T-lymphocytes and B-lymphocytes (reducing their proliferation and secretion of inflammatory factors), they are not broadly immunosuppressive in the same way as traditional immunosuppressant drugs. They have targeted immunomodulatory effects, rather than causing widespread immune suppression. This targeted effect is one reason they are promising for treating GVHD.

What is your success rate?

Follow-up vitality questionnaires indicate that approximately 85% of patients report sustained improvement in their condition within three months of treatment.
