What has actually been tested
- Autologous umbilical cord blood (the child's own banked cord blood), infused intravenously: randomized trials at Duke and in Korea and Australia. The Duke Phase 2 found no overall benefit at one year, but a subgroup receiving a higher cell dose showed greater motor improvement than placebo, prompting further study.
- Allogeneic cord blood or MSCs, with or without erythropoietin: Korean and Chinese randomized trials reported modest gains in gross motor function scores versus control, with effects that were small and variable, and with methodologic concerns in several studies.
- Intrathecal MSCs: mainly uncontrolled series from clinics; no rigorous evidence.
Systematic reviews through 2025 conclude that cell therapies are probably safe in the short term and may produce small improvements in gross motor function in some children, but that the evidence is low certainty and no therapy is established.
Why small motor gains are easy to claim
Children with cerebral palsy improve with age and with therapy. Any intervention delivered alongside intensive rehabilitation and measured over months will show improvement. Only placebo-controlled trials can separate the cells from the growth and the therapy, which is exactly why clinic testimonials, which have neither, tell you nothing.
Red flags specific to pediatric offers
- Intrathecal injections in a child outside a registered trial
- Repeated "rounds" recommended on a schedule, each at full price
- Claims about "brain repair" or "rewiring"
- Packages that include hyperbaric oxygen, chelation or high-dose vitamins
- Pressure to decide quickly, or fundraising templates supplied by the clinic
- No pediatric neurologist or physiatrist on the treating team
What has strong evidence for cerebral palsy
- Early, intensive, goal-directed therapy (physical, occupational, speech)
- Botulinum toxin and other spasticity management
- Selective dorsal rhizotomy for appropriately selected children with spastic diplegia
- Orthopedic surgery for contractures and hip surveillance
- Constraint-induced and bimanual therapy for hemiplegia
Colombia offers all of these at major pediatric centers, and multi-week intensive therapy programs in Bogotá and Medellín cost a fraction of US private programs. That is a legitimate reason to travel with a child. See the hub's family medical travel guide.
If you still want to pursue cell therapy
The only path we can support is a registered trial. Cord blood programs at academic centers in the US, Korea and Australia periodically enroll children, sometimes including those with their own banked cord blood. Search ClinicalTrials.gov for "cerebral palsy" and "cord blood" or "mesenchymal," and contact the study coordinators directly. See finding legitimate trials. We do not refer children for stem cell treatment at clinics.
Regulatory status: FDA vs INVIMA
United States (FDA): The only FDA-approved stem cell products are hematopoietic (blood-forming) cell products for blood cancers and immune disorders. There is no approved stem cell therapy for stroke, cerebral palsy, brain injury, Parkinson's disease, macular degeneration or hearing loss. Legitimate access in the US is through registered clinical trials listed at ClinicalTrials.gov.
Colombia (INVIMA): Cell therapies fall under advanced-therapy regulation. Facilities need INVIMA habilitation and laboratory-processed cell products need product authorization or an approved research protocol. Verify the clinic's INVIMA status and the physician's ReTHUS registration. Neurologic indications are experimental everywhere; a Colombian clinic offering them outside a documented protocol should be treated with corresponding caution.
Frequently asked questions
Do stem cells cure cerebral palsy?
No. Randomized trials show at most small, inconsistent improvements in motor function. No cell therapy is an established treatment.
Is it safe to take my child abroad for stem cells?
Short-term safety in trials has been acceptable, but clinic protocols, especially intrathecal ones, are unmonitored. The bigger risk is financial and the opportunity cost of skipping proven therapy.
What should we do with banked cord blood?
Keep it banked and ask academic trial centers whether an autologous infusion study is enrolling. Do not send it to a commercial clinic.
Researching options for your child?
We can connect you with pediatric rehabilitation and neurology programs in Colombia with real evidence behind them. We do not refer children for stem cell infusions.
