Conventional medicine is a largely reactive field. People typically go to a doctor when they have an illness or injury; they are often prescribed medicine to manage their symptoms.
But what if your goal isn’t to fix a condition or live longer? What if it’s to live better?
That’s where regenerative medicine comes in. This cutting-edge industry is proactive and future-focused. It supports repair at the source, helping people to optimize their body’s performance to match their ambitions. In scientific terms, stem cell therapy uses biologically active cells to support repair signaling and immune regulation [1].
Despite more press coverage on the emerging field, stem cell therapy is still broadly misunderstood. This guide clarifies the science and benefits behind the practice and why high-powered people across the globe – from athletes looking to maximize their physical abilities to driven professionals motivated to extend their careers – are turning to pioneering facilities like RMI Health.
What Is Stem Cell Therapy?
Stem cell therapy is a treatment that uses stem cells – the body’s master cells – to repair and regenerate tissue, and reduce inflammation. Typically, therapeutic stem cells are sourced, processed in a lab, and examined for quality, then delivered to suitable patients in one of two ways:
- Intravenous (IV) infusion through the bloodstream
- Targeted injection into the affected part of the body.
In the world of stem cell therapy, there are two terms you will hear a lot: autologous and allogeneic.
- Autologous stem cells are from the patients themselves.
- They are usually sourced from fat or bone marrow.
- Allogeneic stem cells are from donors.
- They are sourced from bone marrow, whole blood, and umbilical cord tissue.
RMI Health uses allogeneic stem cells known as mesenchymal stem cells (MSCs) for all treatments. These are cells that have the potential to turn into bone, cartilage, and muscle cells [2]. There is substantial evidence to support the safety of MSCs in stem cell therapy for various human conditions [3].
Umbilical cord stem cells for therapy
Umbilical cord MSCs (UC-MSCs) are MSCs derived from donated umbilical cord tissue. They are particularly prized for therapeutic use as they are young, with no markers of aging, and have a low risk of rejection. Compared to a patient’s own autologous stem cells, UC-MSCs are more potent [4]. They are also an off-the-shelf product, so there is no need for invasive extraction procedures from patients or donors.
At RMI Health, we extract all UC-MSCs from umbilical cords donated by consenting people who have given birth via C-section.

Why Are Stem Cells Important in Medicine?
While some stem cells actually increase in numbers over time, our natural pool of stem cells declines in function and diversity as we age. Scientists call this ‘reduced clonal diversity’ – meaning less variety in the types of stem cells. This impacts our ability to heal.
Unlike modern medicine, which typically revolves around pain and condition management, stem cell therapy harnesses the ability of stem cells to regenerate lost or damaged tissue. This form of regenerative medicine is designed to have lasting effects on the whole body. Rather than targeting one issue in isolation, stem cells have the potential to lower systemic inflammation – a major accelerator of chronic illnesses like heart disease and arthritis [5, 6].
How Does Stem Cell Treatment Work?
It’s a common misconception that stem cells directly replace damaged tissue in the body. In reality, stem cells are more like messengers.
Think of stem cell treatment like air traffic control for the body. Both work to maintain order and restore control in busy, high-stakes environments. Just as an air traffic controller watches for emergency signals from planes, injected stem cells look for the biological equivalent: cytokines. These are chemical distress signals from damaged parts of the body. When the stem cells detect cytokines, they migrate towards them and release molecular signals that tell dormant cells to wake up and start repairing.
Stem cell therapy helps modulate the immune system and bring it back to balance. For example, with an autoimmune condition like rheumatoid arthritis, stem cells would downregulate the immune system by secreting anti-inflammatory and growth factors.
In recent years, scientists have found evidence that healthy MSC stem cells can transfer mitochondria – the powerhouses of the cell – to other cells to rescue them from death [7]. This discovery has the potential to transform treatment for life-limiting mitochondrial diseases.

What Conditions Can Stem Cell Therapy Treat?
Stem cell research is an exciting field of science. Doctors and microbiologists across the globe are constantly evolving our understanding of stem cells, with new studies into their mechanisms, uses, and the efficacy of different treatments coming out regularly.
Here are some of the most common fields that regenerative medicine is helping to treat.
Orthopedic & Sports Medicine
Orthopedics is one of the most established use cases for stem cell therapy in clinical practice – especially for joint degeneration, tendon and ligament injuries, and spine-related pain patterns. The goal is to support tissue recovery and help reduce inflammation in the affected area, which can translate into better function and mobility for many patients.
At RMI Health, orthopedic care is tailored to the body region and tissue type involved. Orthopedic Treatment focuses on joints and uses diagnostic ultrasound and joint mapping, followed by targeted injections with ultrasound guidance. Orthrophic is designed for cartilage-focused joint degeneration and includes deeper injections that can target bone structures involved in cartilage support. Orthospine is designed for back and spine concerns, such as degenerative disc disease, with treatment planning that considers the full back, including discs and supporting structures.
Autoimmune Disorders
Autoimmune disorders are conditions that prompt the body to mistakenly attack itself; rheumatoid arthritis, lupus, and multiple sclerosis (MS) are all autoimmune conditions. There is growing evidence to support the effectiveness of stem cell treatment for these diseases [8]. RMI Health uses IV infusions to treat autoimmune conditions, circulating stem cells via the bloodstream. This approach helps reduce the frequency and intensity of flare-ups by regulating the body’s immune response.
Stem cell treatments like IV infusions also have the potential to lower reliance on harsh immunosuppressant drugs that are commonly used to control autoimmune conditions. These medicines can cause adverse side effects and serious long-term risks such as cardiovascular disease and some cancers [9].
Anti-Aging & Longevity
Many patients pursue regenerative medicine as part of a longevity-focused plan, often centered on inflammation management, recovery capacity, and overall resilience. In this setting, treatments are typically systemic and designed to support whole-body signaling and tissue health, rather than targeting one localized injury.
Longevity-focused options at RMI Health include Stem Cell Infusion (IV delivery using UC-MSCs), Plasma Exchange (a blood-based procedure that separates blood components and replaces aged plasma with a clean fluid), and Bio-Insurance (collecting and preserving your own stem cells from blood for potential future use).
Skin and Aesthetics
Stem cell-based approaches are also used in skin-focused protocols, often combined with established aesthetic modalities that target texture, tone, pores, and fine lines. In this context, the goal is appearance-focused improvement, with protocols structured around controlled skin stimulation plus regenerative support.
RMI Health’s Skin Treatment protocol combines microneedling with radiofrequency, CO2 fractional laser, and intradermal stem cell injections, with goals that typically include firmer-looking skin, smoother texture, more even tone, and reduced fine lines.
Sexual Wellness
Stem cell medicine is also used in sexual wellness protocols that focus on tissue health, function, and comfort. These programs are structured around specific goals and combine multiple modalities rather than relying on a single intervention.
Harmony is RMI Health’s female-focused protocol designed to address vaginal and vulvar tissue changes associated with aging and menopause-related symptoms such as dryness and discomfort, using a combination approach that includes regenerative therapies. Enhance is a male-focused protocol designed for erectile dysfunction and sexual wellness goals using a multimodality regenerative approach [10].
How Successful Is Stem Cell Therapy?
A single metric can’t reflect the success of any given stem cell treatment. This is because regenerative medicine is holistic; it aims to reduce pain, restore mobility, and enhance overall quality of life.
Many factors can influence the effectiveness of stem cell therapy, including:
- Cell quality: The quality of stem cells often dictates how successful treatment will be.
- Several factors impact cell quality, from the donor stem cells themselves to the way they are stored.
- RMI Health’s lab is ISO 5 and ISO 7 certified; these industry benchmarks ensure cell quality isn’t negatively affected by the lab environment.
- We provide all patients with a certificate of quantity and quality, guaranteeing an average cell viability rate of 80%.
- Dosage: Each stem cell treatment has its own dosing range based on clinical evidence. It’s not as simple as more stem cells equals better results.
- RMI Health follows evidence protocols carefully, ensuring all patients receive enough stem cells for treatment to be effective, but not too many as to cause harm.
- Medical plan: All stem cell treatments should be tailored to individual needs and expectations. There is no one-size-fits-all approach.
- Treatment at RMI Health starts with a comprehensive consultation process to determine the best course of action.
- Experienced clinicians administer the treatments, monitoring results every step of the way.
- Patient lifestyle: Lifestyle and activity levels play key roles in the success of stem cell therapy.
- Clinicians at RMI Health provide patients with diet, exercise, and post-care advice to ensure they maximize their results.
It’s important to remember that stem cell therapy isn’t an immediate solution. Timelines for recovery will vary based on the condition and treatment type. Some people with inflammatory issues feel immediate relief; others with longer-term goals like tissue regeneration may not notice changes for several months.

Are Stem Cell Treatments Safe?
Many studies have confirmed the safety of UC-MSC therapies in humans [3]. The body rarely rejects these types of cells. However, safety is about more than the biological mechanism of treatment. It also depends on:
- Quality of cells
- Patient suitability for treatment
- Following a tailored medical plan
- Risk identification and mitigation
- Proper therapy administration in a sanitary environment
- Adequate follow-up and aftercare.
As in every field of medicine, a generally safe practice can lead to negative outcomes if improperly administered.
RMI Health is licensed by the Costa Rican Ministry of Health. They closely regulate stem cell clinics to ensure strict safety standards and only license facilities that use verified and uncontaminated products. Our treatments are minimally invasive, using only local anaesthesia and light sedation – there is no need for hospital inpatient care.
Temporary Side Effects of Stem Cell Treatments
The most common temporary side effects of stem cell treatments performed at RMI Health are:
- Temporary flu-like symptoms, such as a fever or body aches
- Mild soreness at the injection site
- Minor fatigue.
Hair loss isn’t an expected side effect of stem cell therapy.
How Much Does Stem Cell Therapy Cost?
The cost of stem cell therapy depends on many things – from the condition to the duration. For example, some treatment protocols are simple while others require multiple visits and specialized injections over a period of time. Realistically, you can expect to pay between $19,000 to over $60,000. This price reflects lab safety, cell quality, and medical expertise. You should be sceptical of clinics offering prices that seem too good to be true.
Stem cell therapy is generally not covered by insurance as it’s still an emerging science.
If you are considering stem cell treatment, it’s important to frame the decision as an investment in your long-term well-being. Can you put a price on a pain-free life? Or avoiding a knee replacement?
Why is Costa Rica the Best Country for Stem Cell Therapy?
Government regulations struggle to keep up with fast-moving fields of science, and stem cells are no exception. The Food and Drug Administration (FDA) tightly restricts which therapies are available and the amount of cells that can be used in the United States. These rules are designed to protect people, but they don’t necessarily reflect newer research.
In Costa Rica, the Ministry of Health regulates the industry differently. For example, the US only allows clinics to use the stem cells they extract in one sitting; these are typically very low counts. Costa Rica, by contrast, permits the culture of stem cells, allowing facilities like RMI Health to provide hundreds of millions of stem cells per treatment.
RMI Health is currently the only facility in Costa Rica licensed to produce and use expanded MSCs. With our US and Europe-trained doctors, we are helping to transform the island nation into a top medical tourism hub. Our personalized concierge service supports every patient, so they can recover in paradise with the support they need.
How to Determine If You Are a Good Candidate for Stem Cell Therapy?
Who Is A Good Candidate for Stem Cell Therapy
The best candidates for stem cell therapy are people who are:
- hoping to avoid or delay surgery, such as joint replacements and spinal fusion
- struggling with chronic pain or autoimmune conditions unresponsive to standard treatments
- battling burnout or brain fog, in search of greater cognitive clarity
- high-performers who don’t have time to spend months in rehab after orthopedic surgery
- investing in preventative care to lower their biological age and reduce systemic inflammation
- athletes with chronic overuse injuries like tendonitis who want to avoid lengthy surgical recovery timelines
- wanting to reduce their reliance on harsh immunosuppressant drugs
- seeking expanded cell protocols that aren’t legally available in the US.
Who Is Not A Good Candidate for Stem Cell Therapy
Some people are not well-suited to stem cell therapy, including:
- pregnant people
- active cancer patients – the growth factors released by stem cells during treatment could theoretically stimulate cancer cells
- individuals with active infections – you must be deemed healthy enough by a doctor.
What Is the Recovery Process Like After Stem Cell Therapy?
First 48 Hours (The Homing Phase)
When transplanted stem cells are first introduced, they start circulating in search of cytokines, which signal damage in the body. Rest is crucial during this first phase of recovery, so the cells can focus on getting where they need to go efficiently.
Weeks 1-2 (The Integration Phase)
As the stem cells begin to integrate into your body, you can introduce light, low-impact movement such as walking and swimming. These activities stimulate blood flow, so they will help the stem cells circulate.
You should avoid heavy lifting or high-intensity cardio as both could create new inflammation and distract the stem cells from travelling to the target areas.
Weeks 2-8 (The Optimization Phase)
Hydration is crucial between weeks two and eight. Water supports the movement of cells and helps them to function correctly. It’s also essential to follow an anti-inflammatory diet, focusing on foods like tomatoes, olive oil, green leafy vegetables, and antioxidant-rich fruits such as strawberries and blueberries [11].
Your treating team will check in with you throughout this period and set up follow-up communications to measure your progress.
What Shouldn’t You Do After Stem Cell Treatment?
After stem cell treatment, it’s very important to:
- Avoid non-steroidal anti-inflammatory drugs (NSAIDs) like Advil and Aleve until cleared by your treating team.
- These medicines block the body’s distress signals, making it very difficult for the stem cells to find the damaged parts of the body where they need to go.
- Stop smoking cigarettes and drinking alcohol.
- Pause all high-impact sports
- Returning to intense sports too early can disrupt the fragile cell repair process.
