STROKE · Stem cell & exosome therapy
Stem cell therapy for stroke recovery that goes beyond what rehabilitation alone can achieve.
If you are a stroke survivor looking for stem cell therapy options beyond conventional rehabilitation, Alevy’s regenerative medicine clinic in Pereira, Colombia offers science-backed MSC treatment for patients in the chronic recovery phase — with protocols built around your specific stroke history and goals.
Are you experiencing any of these?
Stem cell therapy for stroke recovery could change what's still possible
Neurological recovery after stroke is time-sensitive. The sooner regenerative therapy begins, the greater the potential for meaningful improvement. Stem cell therapy works at the cellular level to support repair that standard rehabilitation cannot reach. If you are living with any of the following, you may be a candidate for treatment.
Motor weakness, coordination difficulties, or paralysis after stroke
Speech or language challenges that haven't fully resolved
Cognitive changes: memory, processing speed, mental clarity
Spasticity, muscle stiffness, or chronic post-stroke pain
A rehabilitation plateau with functional limitations still present
A desire to keep recovering and not just manage what remains
What is a Stroke?
When blood supply to the brain is cut off, neurons begin to die
A stroke occurs when blood flow to part of the brain is suddenly blocked — most commonly by a clot in a blood vessel. Without oxygen, brain cells begin to die within minutes. The region of the brain affected determines what functions are lost: movement, speech, memory, coordination, or all of the above.
Stroke is the most common neurological disorder in adults, and its incidence has risen with population aging and the growing prevalence of cardiovascular disease. Advances in acute care have improved survival rates — but many survivors are left with lasting cognitive, sensory, and motor impairments that conventional medicine has no mechanism to reverse.
The nervous system has very limited capacity to regenerate on its own. Once neurons are lost, standard treatment cannot replace them. This is where the gap between survival and recovery opens — and where regenerative medicine is changing what is possible.
At its root, the condition involves abnormal protein aggregation in the brain and a breakdown of the blood-brain barrier that normally regulates what enters and exits the central nervous system. When the barrier fails, inflammation follows — and neuronal damage accelerates.
Across the current research literature, stem cell transplantation in acute, subacute, and chronic ischemic stroke is considered safe and has been linked to neurological improvement — including reduced disability, lower recurrent stroke risk, and improved survival. Multiple randomized controlled trials, systematic reviews, and meta-analyses support this safety and efficacy profile across different administration routes and doses. Intravenous delivery is generally considered safest during the acute and subacute phases, while intrathecal delivery is supported as the preferred route in the chronic phase.

HOW CAN ALEVY'S ADVANCED THERAPY TREATMENTS HELP YOU?
Targeting the cellular basis of post-stroke disability
Stem cell therapy supports stroke recovery through several documented mechanisms, each targeting a different aspect of the neurological damage caused by the stroke
Neuroprotection
MSCs release neurotrophic factors that help surviving neurons remain functional — preventing further deterioration in affected brain regions and supporting the conditions needed for recovery. Source: Zhu et al., Glob Med Genet 2024
Inflammation control
Chronic brain inflammation after stroke worsens disability and blocks recovery. MSCs actively modulate this inflammatory response by creating an environment where the brain can begin to repair rather than continue to deteriorate. Source: Song et al., Cell Commun Signal 2024
Myelin regeneration
The myelin sheath surrounding neurons which is essential for efficient nerve signal transmission is often damaged after stroke. MSC therapy supports myelin repair, improving the speed and quality of signals between brain regions. Source: Vagionitis & Káradóttir, Brain 2024
Blood-brain barrier restoration
Stroke compromises the blood-brain barrier that protects neural tissue, allowing further damage after the initial event. MSCs and exosomes help restore barrier integrity by limiting ongoing harm and stabilizing the recovery environment. Source: Li et al., Int J Nanomedicine 2024
Functional recovery for motor, speech, cognition

Why Alevy for stroke recovery
What separates Alevy from the options available at home
Stroke recovery is not linear and no two cases are identical. The type of stroke, the regions affected, the time elapsed, and the patient’s current functional status all shape what treatment looks like. Our medical team has spent over 10 years building the clinical depth that conditions this variable demand.
ISO-certified biotechnology laboratory
Our lab in Pereira operates under international quality standards with processes and documentation that most clinics in North America and Europe cannot match in-house.
Wharton's jelly MSC sourcing
Ethically sourced mesenchymal stem cells from umbilical cord tissue — ISCT compliant, high potency, and with a low immune rejection profile. The same cell source linked to BBB protection in recent research.
High-dose protocols
Cell dosage ranges that exceed what regulatory restrictions currently permit in the US and Canada — administered under direct clinical supervision by our medical team.
Potent donor cells, not your own
Most clinics in the US and Canada that do offer stem cell therapy use cells harvested from the patient's own fat tissue. For stroke survivors, these are the same aged cells affected by the conditions that contributed to the stroke in the first place. Alevy uses cells from healthy newborn donors biologically young, unaffected by disease, and at peak regenerative potency.
10+ years of clinical experience
Our medical team has treated complex neurological cases across more than 10 years. Providing experience that most regenerative medicine clinics at this stage of the field don't have.
FREQUENTLY ASKED QUESTIONS
Your Questions Answered
01 Is stem cell therapy for stroke available in clinical trials?
Stem cell therapy for stroke has already moved well beyond the early clinical trial phase. Multiple randomized controlled trials, systematic reviews, and large meta-analyses have confirmed both the safety and efficacy of MSC-based therapy across acute, subacute, and chronic phases of ischemic stroke. At Alevy, we do not enroll patients in clinical trials. We provide actual treatment using protocols informed by this established body of research.
The evidence base behind our protocols is reviewed in detail in the research section above, where you can read summaries of the key studies and access the original publications directly. The science is no longer experimental. Patients who come to Alevy are receiving treatment grounded in peer-reviewed research and not participating in it.
02 How effective is stem cell therapy for stroke?
The clinical evidence shows meaningful neurological improvement in stroke patients treated with stem cell therapy, particularly those in the chronic recovery phase. Across multiple systematic reviews and meta-analyses, MSC-based therapy has been associated with improvements in motor function, speech and language, cognitive clarity, and overall disability scores — in patients who had already reached the limits of conventional rehabilitation.
It is important to be clear about what effectiveness means in this context. Stem cell therapy does not reverse all damage caused by a stroke. What the research consistently shows is that it supports the brain's own repair mechanisms at the cellular level — reducing inflammation, promoting new blood vessel formation, and supporting myelin repair — in ways that rehabilitation alone cannot. The result for many patients is continued functional recovery that would not have occurred otherwise.
Results vary between individuals and depend on factors including the type of stroke, the regions of the brain affected, the time elapsed since the stroke, and the patient's current functional status. Improvement is gradual and develops over months following treatment, not days or weeks. You can review the specific studies supporting these outcomes in the research section above.
03 Which clinics provide FDA-approved stem cell treatments for stroke patients?
Currently, there are no FDA-approved stem cell treatments for stroke. The FDA's regulatory framework has not approved any stem cell therapy specifically for stroke recovery, which means that patients in the United States and Canada have very limited access to this treatment — and what is available is often restricted in cell source, dosage, and delivery method.
Some US-based clinics do offer stem cell procedures under specific regulatory exemptions, but these typically use adipose-derived cells — harvested from the patient's own fat tissue. These are the patient's own aged cells, affected by the same health conditions, lifestyle factors, and biological aging that contributed to the stroke in the first place. Dosages are also generally low, further limiting therapeutic potential.
Patients who seek treatment outside the US are often doing so precisely because international clinics operating under rigorous scientific and quality standards can offer something fundamentally different. At Alevy, we have been working with stem cells in our ISO-certified biotechnology laboratory for over 15 years and providing safe, certified treatments for more than a decade. Our protocols use fresh Wharton's jelly mesenchymal stem cells sourced from healthy newborn umbilical cord tissue — biologically young, high potency cells that are ISCT compliant and unaffected by the patient's age or medical history. This is not a workaround. It is a clinically superior approach backed by peer-reviewed research, delivered by board-certified physicians in a certified facility.
04 How much does stem therapy cost for stroke treatment?
The cost of stem cell therapy for stroke varies depending on several factors specific to each patient — including the cell dosage recommended, the delivery method, the complexity of the case, and any complementary therapies indicated as part of the protocol. A single price does not apply across all patients because no two treatment plans are identical.
What we can tell you is that treatment at Alevy includes far more than the stem cell administration itself. Your protocol encompasses a comprehensive medical evaluation, customized treatment plan, laboratory processing, all clinical procedures, complementary therapies, bilingual patient care support, and post-treatment follow-up monitoring.
The most accurate way to understand what treatment would cost for your specific situation is to submit your medical history for review. Our medical team will prepare a personalized protocol with full details at no cost and with no commitment required. You can request yours by filling out the form and requesting a call from out Patient care Specialists.
05 Where can I get stem cell therapy for stroke?
Stem cell therapy for stroke is not widely available in the United States or Canada due to FDA regulatory restrictions that limit cell sourcing, expansion, dosage, and protocol design. Patients who are serious about accessing the most advanced regenerative treatment available typically look outside North America where clinics can offer protocols that the US and Canadian markets currently cannot.
Alevy has locations in Medellin and Pereira, Colombia. We have been providing stem cell therapy for neurological conditions for over a decade, operating out of our ISO-certified biotechnology laboratory with ISCT-compliant protocols and board-certified physicians.
Colombia has become one of the leading destinations for medical tourism in Latin America precisely because of the quality of care available at a fraction of the cost patients would expect in North America, without compromising on clinical standards. For stroke survivors specifically, Pereira offers something most places cannot: a clinic with over 10 years of stem cell and exosome experience, fresh Wharton's jelly MSCs processed on site at our lab with 15 years of experience, and intrathecal delivery protocols matched to the chronic recovery phase.
