Stem cells come from several places in the body and can be obtained through medical facilities, donor registries, cord blood banks, and clinical trials. Where you actually get them depends on whether you need stem cells for a medical treatment, want to donate them, or are looking to bank them for future use. The average cost for stem cell therapy in the U.S. is around $10,000, though prices range widely, and most treatments outside of bone marrow transplants are not covered by insurance.
Biological Sources of Stem Cells
Stem cells exist throughout the human body, but only a handful of locations yield enough cells to be medically useful. The three primary sources in adults are bone marrow, fat (adipose) tissue, and circulating blood. Newborn tissues offer additional options: umbilical cord blood, the cord itself (specifically a layer called Wharton’s jelly), and the placenta are all rich in stem cells. Amniotic fluid and even the dental pulp inside baby teeth contain harvestable cells.
These sources produce two main types of stem cells used in medicine. Hematopoietic stem cells, found primarily in bone marrow and cord blood, generate all the components of blood and are the basis for bone marrow transplants used to treat cancers like leukemia and lymphoma. Mesenchymal stem cells are found in bone marrow, fat tissue, umbilical cord, and synovial fluid in joints. They can develop into bone, cartilage, muscle, and fat cells, making them the focus of research into osteoarthritis, autoimmune diseases, and tissue repair.
Stem Cell Therapy Clinics in the U.S.
Hundreds of clinics across the United States offer stem cell injections for joint pain, back injuries, neuropathy, and other conditions. Most of these use your own cells (autologous), typically harvested from your bone marrow or fat tissue during the same visit. The cells are processed and injected into the treatment area, often within a few hours.
Costs vary significantly by condition. Knee injections typically run $5,000 to $10,000. Back and shoulder treatments range from $5,000 to $15,000. Treatments for vision loss start around $20,000 and go higher. Neuropathy treatments range from $2,500 on the low end into the tens of thousands. These prices have been climbing: the most common price patients reported in 2019 was $2,500 to $5,000, while in 2025 it shifted to $5,000 to $10,000.
Insurance generally does not cover these procedures. Medicare covers established bone marrow transplants for conditions like blood cancers, but it does not cover unproven or experimental stem cell treatments. That means most patients pay entirely out of pocket.
How to Spot an Unsafe Clinic
The FDA has repeatedly warned that many clinics market stem cell products without the required approval, claiming their treatments fall outside drug regulations. The agency considers this false. Any stem cell product that is processed beyond minimal manipulation, or used for a purpose different from its original function in the body, is regulated as both a drug and a biological product. Legally marketing it requires either an approved biologics license or an active investigational application for use in clinical trials.
The International Society for Stem Cell Research identifies several warning signs to watch for: clinics that rely on patient testimonials as proof, claims that the treatment carries no risks, vague or extremely long lists of treatable conditions (some clinics list everything from migraines to major neurodegenerative diseases on a single page), lack of transparency about what cells are being injected, and hidden costs that emerge after the initial consultation. If a clinic cannot clearly explain the source of the cells, the regulatory status of the treatment, and the evidence behind it, that is a reason to look elsewhere.
Clinical Trials
For people interested in accessing experimental stem cell therapies through a regulated pathway, clinical trials offer a legitimate option. The federal database at ClinicalTrials.gov lists active studies by condition, location, and enrollment status. You can search by your specific condition and filter for trials recruiting participants near you. Universities and academic medical centers run most of these trials, and participation is typically free since the research team covers treatment costs.
Clinical trials go through multiple phases to evaluate safety and effectiveness, so not every trial guarantees you will receive the stem cell treatment (some participants receive a placebo). But trials offer medical oversight, documented protocols, and follow-up care that commercial clinics often lack.
Cord Blood Banking
Parents can collect stem cells from their baby’s umbilical cord blood at birth, but you need to arrange this before delivery. There are two routes: public banks and private banks.
Donating to a public cord blood bank is free. The bank covers collection, testing, and storage costs. The donated cord blood becomes available to any patient who needs a transplant, and if it cannot be used for transplantation, it may go to research or be discarded. The tradeoff is that the family gives up ownership. Not every hospital participates in public cord blood collection, so you need to check whether your delivery hospital works with a public bank.
Private cord blood banks store your baby’s cord blood exclusively for your family’s future use. This comes with upfront processing fees (typically $1,000 to $2,500) plus annual storage fees. The advantage is guaranteed access if a family member ever needs those cells. The limitation is that most families never end up using them, and the range of proven treatments for which cord blood is currently used remains relatively narrow, primarily blood disorders and certain cancers.
Donating Stem Cells Through a Registry
If you want to donate stem cells to someone who needs a transplant, the main pathway in the U.S. is through the NMDP registry (formerly Be The Match). You are eligible to join if you are between 18 and 35, a U.S. resident, and able to meet the organization’s health guidelines.
Registration starts online. You order a free swab kit, which arrives in three to seven days. You swab your cheeks, mail the kit back in a prepaid envelope, and the registry processes your tissue type. After that, you wait. Because tissue matching is complex, some donors are called within months while others wait years or are never matched. About 90% of donors give through a process called peripheral blood stem cell donation, where circulating blood is drawn, stem cells are filtered out by a machine, and the remaining blood is returned to your body. Collection sessions can take one to five days depending on how many cells are needed. Common side effects include bone pain, headache, fatigue, and nausea. Most donors resume normal activities within a few days, though heavy lifting should be avoided for about two weeks.
Overseas Clinics and Stem Cell Tourism
Clinics in China, India, Mexico, Panama, Thailand, and Ukraine actively market stem cell therapies to international patients, often for conditions that have no approved stem cell treatment anywhere in the world. Prices vary but can run $20,000 and up for conditions like autism or neurological diseases.
The risks are real and documented. Reported complications include meningitis following injections, brain and spinal tumors in a boy in Russia who received fetal neural stem cells, and serious kidney lesions from a transplant. In some cases, patients do not even know exactly what is being injected. Protocols are poorly documented, quality of facilities varies enormously, and follow-up care after returning home is rarely part of the plan. Your doctors back home may have limited ability to manage complications from an unknown procedure performed abroad.
None of this means every international clinic is fraudulent, but the lack of regulatory oversight in many countries means patients bear the full burden of evaluating safety. If a clinic abroad promises results for a long list of unrelated conditions, charges large fees upfront, and cannot provide published clinical data supporting its treatment, those are the same red flags that apply domestically.
