Am I eligible for Stem Cell Treatment?

Eligibility is determined in steps: a medical questionnaire and record review, a consultation with the doctor, and a final in-person evaluation with laboratory testing on the day of your appointment. The purpose of this process is to match the condition, treatment goals, cell dose and route to the right patient profile. Some situations require additional clearance or simply waiting until a temporary issue, such as an infection or unstable medical condition, has been resolved.

This guide explains the criteria, the evaluation process and the factors the medical team uses to build a safe, appropriate treatment plan.

The three questions behind eligibility

Every evaluation tries to answer three questions:

1. Is there a reasonable basis for regenerative treatment in your condition? Evidence is strongest for conditions such as knee osteoarthritis and degenerative disc disease, growing for several neurological, cardiac and autoimmune conditions, and early for others. The doctor considers whether your specific diagnosis and stage make benefit plausible.
2. Is it safe for you now? Your general health, medications and other conditions determine whether treatment can be done safely and when.
3. Are your goals realistic? Treatment is appropriate when goals, such as less pain, better function or support for quality of life, can reasonably be met. It is not appropriate when the expectation is a guaranteed cure.

Common reasons for being eligible

• Musculoskeletal conditions: mild to moderate osteoarthritis, tendon and ligament injuries, chronic joint pain and disc-related back or neck pain confirmed on imaging, with inadequate response to conservative care.
• Selected neurological, cardiac, autoimmune and inflammatory conditions: when the patient is medically stable and seeks a supportive approach alongside standard care.
• Sexual wellness, hair and aesthetic goals: after evaluation of underlying causes.

Which conditions are most often treated

People who receive regenerative treatment at Stem Cell Mexico most often have one of these profiles:

• Joint and sports problems: mild to moderate osteoarthritis of the knee, hip, shoulder, ankle or hand; tendinopathies; partial tendon or ligament tears; meniscus or labrum problems.
• Spine problems: chronic back or neck pain related to degenerative disc disease or facet joint arthritis.
• Neurological conditions: selected patients with stroke, traumatic brain injury, multiple sclerosis, Parkinson's disease or spinal cord injury who are medically stable and seek a supportive approach alongside standard care.
• Cardiac, kidney and inflammatory conditions: selected stable patients, always as a complement to their specialists' care.
• Sexual wellness, hair and aesthetic goals: after evaluation of underlying causes.

Evidence varies widely between these groups, which is why eligibility is decided case by case rather than by diagnosis alone.

Situations that may require waiting or additional medical clearance

Cancer

Active cancer or cancer diagnosed or treated within the past five years. The safety of cell therapies has not been established in patients with active cancer or recent remission, so we require at least five years of documented remission with imaging and oncology follow-up notes.

Active infection

Any active infection, including urinary tract infections, skin infections near an injection site or recent respiratory illness, must be resolved first.

Pregnancy and breastfeeding

Regenerative treatments are not performed during pregnancy or breastfeeding, because safety has not been studied.

Unstable medical conditions

Recent heart attack or stroke, unstable heart failure, uncontrolled blood pressure or diabetes, rapidly worsening kidney function, uncontrolled seizures or a recent relapse of an autoimmune condition. Many of these patients can be reconsidered once stable.

Conditions that need another treatment first

• Complete tendon or ligament ruptures that require surgical repair.
• Severe joint destruction where joint replacement is the better option.
• Nerve compression with progressive weakness, or bladder or bowel changes, which need urgent surgical evaluation.
• Sudden hearing loss, which needs urgent ENT treatment.
• Active wet macular degeneration that needs ongoing eye injections.

Bleeding risk

Bleeding disorders or blood thinners that cannot be safely managed may make certain injections unsafe, particularly spinal procedures.

Prosthetic joints

Joints that have been replaced are not injected with cells.

Fit between the condition and treatment goals

The doctor reviews whether your diagnosis, stage of disease and goals match the type of benefit being studied with regenerative therapy. If the fit is not strong enough to justify proceeding, the team will explain why and what additional information or alternative path may be more appropriate.

Infectious disease screening

As part of the medical questionnaire and laboratory work, you may be asked about conditions such as hepatitis B, hepatitis C and HIV. These questions are standard in procedures that involve injections and handling of biological materials. A positive history does not automatically exclude you, but it is important for planning, staff safety and your own care, and some situations, such as an uncontrolled infection or significant liver disease, may require stabilization or specialist input first. All information is kept confidential.

Factors that do not automatically exclude you

• Age: there is no strict upper age limit; older adults are frequently treated, with additional attention to heart health, medications and fall risk.
• Weight: a high BMI does not exclude treatment, although some imaging, such as MRI, may require an open machine.
• Previous surgery: prior spine or joint surgery is reviewed but does not automatically rule out treatment.
• Chronic conditions: well-controlled diabetes, high blood pressure or thyroid disease are common among patients.
• Previous stem cell treatments: past treatments are reviewed, including when and what was used.

A few examples

A 62-year-old with moderate knee osteoarthritis, no other major health problems and pain despite physical therapy is often a good candidate for a targeted joint treatment.

A 70-year-old with stable heart failure on optimized medication may be considered for a supportive protocol after cardiology records are reviewed and with extended monitoring.

A 55-year-old who finished breast cancer treatment two years ago would need to wait until five years of documented remission.

A 45-year-old with a complete rotator cuff tear and retraction would usually be advised to see an orthopedic surgeon first, because the tear likely needs repair.

A person with a urinary tract infection the week of travel would have treatment postponed until the infection is resolved.

These examples are simplified; your own evaluation considers your full history.

The eligibility process step by step

1. Medical questionnaire

You complete a medical history form with your diagnosis, symptoms, prior treatments, medications, allergies and relevant conditions. Be complete and accurate; inaccurate information can lead to an inaccurate evaluation or cancellation on arrival.

2. Records and imaging review

You send recent imaging (for example, an MRI no older than three months for joint or spine problems), lab results and specialist reports.

3. Consultation with the doctor

A phone or video consultation, which is complimentary, allows the doctor to discuss your goals, explain whether treatment is reasonable and answer questions.

4. Written plan

If you appear to be a candidate, you receive a written plan and quote.

5. Final in-person evaluation

On arrival, laboratory tests (complete blood count, metabolic panel, urinalysis and tumor markers) and an in-person examination confirm eligibility. If results reveal a new problem, such as an infection or abnormal values, the doctor may postpone or cancel treatment for your safety.

What happens if you are not eligible

Being told that you are not a candidate can be disappointing, but it is a sign of responsible care. We will explain the reasons, share our recommendations, and in many cases suggest when you could be reconsidered, for example after an infection is treated, after a medical condition is stabilized or after completing another necessary treatment. We may also recommend that you discuss specific options with your local specialist.

Why honest screening protects you

The International Society for Stem Cell Research (ISSCR) encourages patients to be cautious with providers who accept everyone, promise results or skip a medical evaluation. The FDA has similarly warned consumers about unproven stem cell products marketed for a wide range of conditions. Careful eligibility screening is one of the most important safety measures in regenerative medicine. Large safety analyses of MSCs in controlled trials show a favorable profile, with temporary fever as the most consistent side effect of infusions, but those results come from screened patients, which is exactly why screening matters.

How to prepare for your evaluation

• Gather recent imaging with reports, lab results and specialist notes.
• Make a complete list of medications and supplements with doses.
• Write down your main goals and what you have already tried.
• Note any history of cancer, infections, bleeding problems or allergies.
• Prepare your questions.
• If possible, ask your regular doctor for a brief summary of your medical history and current treatments; it speeds up the review and reduces the chance of missing important information.

Questions to ask during your evaluation

• Based on my diagnosis, is there a reasonable basis for regenerative treatment?
• Is there anything that makes treatment unsafe for me now?
• What results are realistic for my condition?
• Would another treatment be better as a first step?
• If I am not eligible now, what would need to change?

Bottom line

Eligibility for stem cell treatment depends on having a condition with a reasonable basis for regenerative therapy, stable health and realistic goals, confirmed through a questionnaire, record review, consultation and final in-person evaluation. Cancer within five years, active infection, pregnancy and unstable conditions are common reasons to wait or decline. A medical evaluation can help determine whether this type of regenerative treatment is appropriate for your condition, goals and medical history.
