Why was I recommended a specific number of stem cells? Are more cells better?

A higher number of cells does not always mean a more appropriate treatment. The goal is the right dose, delivered to the right place, with the right technique. The number of cells is only one part of the full picture: the source of the cells, their viability, how they are handled, the application technique, the experience of the medical team, safety standards and follow-up all play an important role in your treatment.

Patients who compare quotes from different clinics often notice that the cell counts vary a lot, from a few million to several hundred million. It is natural to wonder whether the plan with the biggest number is the best one. This guide explains how your dose is decided, why more cells are not automatically better and what to look at when you compare proposals.

How your dose is decided

At Stem Cell Mexico, every treatment plan is personalized after a medical evaluation. Before you receive a quote, our stem cell specialist reviews your case, usually through a free telemedicine evaluation, together with the information you send, such as your medical questionnaire, imaging and reports. The recommendation considers:

• Your diagnosis: a joint problem, a spine condition and a systemic or neurological goal require different approaches.
• Your imaging: an MRI or X-ray shows how much damage there is and where it is located.
• The level of degeneration and inflammation: early wear and advanced damage are treated differently.
• The number and size of the areas treated: a knee and a finger joint do not need the same dose, and two knees need more cells than one.
• Your mobility and symptoms: how much pain you have and how it affects your daily life.
• Your medical history and laboratory results: your overall health and any other conditions.
• The route of application: direct injection into a joint or the spine, IV infusion, or both.

With this information, the doctor defines a dose that fits your case, and your quote reflects that plan.

Typical ranges in our treatment plans

As a reference, these are the ranges you will usually see in the proposals we send:

These are ranges, not fixed packages. A patient with minimal degeneration in a small joint may need a smaller dose, or even platelet-rich plasma (PRP) alone. A patient with several affected areas, or with a systemic or neurological condition, may need a larger total dose, sometimes combining targeted injections and an IV infusion.

Why more cells are not automatically better

The joint has limited space

A joint is a closed space with a limited volume. Each application has to fit in that space together with PRP. The goal is to deliver the cells where they can act, with the right volume for that joint, and the doctor plans the dose with that in mind.

Mesenchymal stem cells work through signals

Mesenchymal stem cells (MSCs) from Wharton's jelly act largely through the signals they release: growth factors, cytokines and extracellular vesicles that help regulate inflammation and support the body's own repair processes. A review in Frontiers in Immunology on MSC delivery explains that how and where the cells are delivered influences where they act and how long they remain in a tissue. In other words, the route, the target and the technique matter as much as the number.

The best dose depends on the case

A dose that is right for advanced arthritis in a large joint is not the same as the dose for early wear in a small one. Choosing a higher number than the case requires adds cost without a clear benefit for that patient. This is why our recommendation is based on your evaluation, not on a standard maximum.

Quality matters as much as quantity

A dose of 100 million cells only works as a dose of 100 million cells if those cells are alive and of good quality. Our cells are released with viability greater than 97%, and they are grown under hypoxic conditions that support viability of up to 98%. When you compare proposals, ask how many of the cells will be alive at the time of application, not only how many cells are listed.

What the research says about dose

Clinical studies of MSCs have used a wide range of doses, depending on the condition and the route. For knee osteoarthritis, a 2024 systematic review and meta-analysis of randomized controlled trials published in the Journal of Orthopaedic Translation reported improvements in pain and function with MSC injections in many of the included trials, which used different cell sources and doses. For IV administration, large safety meta-analyses published in EClinicalMedicine in 2020 and in Stem Cells Translational Medicine in 2026 pooled trials with a broad range of doses and reported that intravascular MSCs continue to appear safe.

What these studies show, together, is that there is no single "correct" number of cells for every patient. The dose is chosen for the condition, the route and the individual case, which is how our medical team works.

Comparing quotes from different clinics

We understand that pricing and cell counts can feel confusing when you are comparing clinics side by side. Here are the points worth comparing, beyond the number on the quote:

• Source of the cells: what tissue the cells come from and whether they are expanded mesenchymal stem cells. Our cells are allogeneic MSCs from Wharton's jelly of donated umbilical cords.
• Viability: how many of the cells are alive.
• Handling and preparation: how the cells are stored and prepared for your date.
• Application technique: whether joints are treated with ultrasound guidance and the spine with fluoroscopy, so the cells reach the right place.
• Complementary therapies: whether PRP is included in joint treatments.
• Medical team and evaluation: whether the plan is designed after a medical evaluation with a specialist.
• Monitoring: whether you stay a night at the facility under nursing and medical monitoring.
• What is included: consultation, laboratory tests, transportation and follow-up.
• Follow-up: our plans include a 12-month follow-up program after your treatment.

Our pricing is based on the full medical experience and support around the treatment, not only on the cell count.

Can I ask for a different dose?

Yes. If you would like to understand your dose, or you are considering a different option, you can talk with your advisor and with the medical team. In some cases, we can share more than one option, for example a standard plan and a plan with a higher number of cells, so you can compare them with the doctor's explanation. The final recommendation is always based on what the doctor considers appropriate for your condition.

How the dose affects the price

The price of your treatment depends largely on the number of cells your plan requires and the method of application. This is why two patients with different conditions receive different quotes, and why a plan with more areas or a larger IV dose costs more. Your written plan lists the number of cells, the route and everything included, so you know exactly what you are paying for.

Common questions

Will I get better results if I pay for more cells? Not necessarily. The right dose for your case is the one that fits your condition, imaging and goals. A higher dose than your case requires does not guarantee a better outcome.

Can the dose change after my in-person evaluation? Yes. If the doctor finds something different during your in-person consultation or in your laboratory results, the plan can be adjusted, and your advisor will explain any change before treatment.

Why did another clinic offer me a much higher number? Clinics use different cell sources, preparations and ways of counting cells. Compare the source, viability, technique, monitoring and follow-up, not only the number.

Can I add an IV infusion to my joint treatment? Yes. Some patients combine a targeted injection with an IV infusion to support the body's overall inflammatory response. The doctor will tell you whether it adds value in your case.

Can I receive a second application later? Some patients receive additional applications over time. During your follow-up, the medical team reviews your progress and tells you whether another application could help.

Questions to ask your doctor

• Why is this dose right for my condition?
• How many areas will be treated, and how many cells in each?
• Would an IV infusion add value in my case?
• How will we measure my progress during follow-up?

Bottom line

Your number of stem cells is recommended by the doctor after reviewing your condition, imaging, degeneration, inflammation, mobility, symptoms and medical history. More cells are not automatically better: the right dose, high viability, precise application and good follow-up are what make a treatment plan appropriate. Results vary between patients, and no dose can guarantee a specific outcome. A medical evaluation can help determine whether this type of regenerative treatment is appropriate for your condition, goals and medical history.
