Stem cell treatment for autism is an investigational therapy, not a cure. The largest randomized trial to date—180 children at Duke University—found that cord blood infusion was safe but did not improve social communication across the full group. Smaller studies and meta-analyses report improvements on several behavior rating scales, so research continues. Renovo evaluates each child individually, and its neurological protocols use dental pulp stem cells.

What Is Autism Spectrum Disorder?
Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects social communication and interaction and includes restricted or repetitive behaviors and interests. It is called a spectrum because abilities and support needs vary widely from person to person. Many autistic people also experience sensory sensitivities, and some have co-occurring conditions such as anxiety or sleep problems.
Established supports—including behavioral therapy, speech and language therapy, occupational therapy, educational services, and parent training—remain the foundation of care. Any regenerative therapy should be considered alongside these supports, never instead of them.

Why Families Explore Stem Cell Therapy for Autism
Researchers have studied whether immune and inflammatory differences play a role in some cases of autism. Mesenchymal stromal cells release signals that can modulate immune activity, which is why teams at Duke University and elsewhere have tested cell therapies in carefully designed trials (Sun et al., Stem Cells Translational Medicine, 2020). Understandably, many families want to know whether these therapies could help their child—and what the evidence actually shows.
What Clinical Trials Show
The largest randomized trial
In a phase II randomized, placebo-controlled trial at Duke University, 180 children ages 2 to 7 received a single infusion of their own umbilical cord blood, donor cord blood, or a placebo. The infusions were safe and well tolerated, but across the full group there was no evidence of improvement in the primary outcome—social communication—or in secondary measures of autism symptoms and vocabulary (Dawson et al., Journal of Pediatrics, 2020).
Umbilical cord tissue MSCs
A Duke phase I study gave umbilical cord tissue MSCs to 12 children with autism. The cells were well tolerated apart from agitation during IV placement; five children developed new antibodies that caused no symptoms; and six of the 12 improved on at least two autism-specific measures. Because this study had no control group, it could not show whether the cells caused those changes (Sun et al., 2020).
What meta-analyses report
A 2022 meta-analysis of 11 trials including 461 patients reported improvements on several autism rating scales in treated groups. The most common side effects were fever, hyperactivity, vomiting, headache, and aggressiveness, with no serious adverse events, and the authors called for further studies to increase confidence in the results (Villarreal-Martinez et al., Stem Cell Reviews and Reports, 2022).
A separate 2022 meta-analysis of five controlled studies found lower scores on the Childhood Autism Rating Scale with stem cell therapy than in comparison groups, but similar overall improvement rates on the Clinical Global Impression scale—62% with stem cells versus 60% in control groups—and no difference in adverse reactions (Qu et al., Frontiers in Pediatrics, 2022).
Taken together, the research shows acceptable short-term safety in clinical trials, possible improvements on some measures, and no proof of broad benefit. That is the context Renovo shares with every family.
About Dental Pulp Stem Cells
For brain-related and neurological conditions, including autism, Renovo’s protocols use dental pulp stem cells (DPSCs), selected for their neurotrophic, neuroprotective, and immunomodulatory properties. Most published autism trials have studied umbilical cord blood or umbilical cord tissue cells, so clinical research on DPSCs for autism is at an earlier stage. Dr. Jiménez explains the reasoning behind any protocol he recommends. Learn more about our approach to neurological disorders and cerebral palsy.
Stem Cell Therapy Autism Success Stories: How to Read Them
It is natural to look for success stories, and every family’s experience matters. Still, individual stories cannot predict how another child will respond. Children continue to develop over time, most families continue other therapies in parallel, and in controlled studies, children in comparison groups often improve too—in one meta-analysis, overall improvement rates were about 60% in both groups.
If you read or watch a success story, ask what was measured, over what period, and what other therapies the child received. You can hear from Renovo patients on our testimonials page, and Dr. Jiménez will explain how progress would be tracked for your child.
How Renovo Evaluates a Child for Stem Cell Therapy
- Medical history and records. Parents share the diagnosis, developmental evaluations, current therapies, medications, and medical history.
- Physician review. Dr. Jiménez reviews every case. Renovo declines or postpones treatment when contraindications—such as an active, uncontrolled infection or medical instability—would compromise safety.
- An honest conversation about the evidence. Families hear what the research does and does not show before any recommendation is made.
- Personalized protocol. The route and dose are determined by Dr. Jiménez, and any intrathecal application is performed in Renovo’s specialized Procedure Room.
- Continued care at home. Families continue established therapies, and follow-up focuses on the goals that matter to the child and family.
Safety and Side Effects
In clinical trials, reported side effects have included fever, hyperactivity, vomiting, headache, aggressiveness, and agitation during IV placement, and some children developed antibodies that caused no symptoms. Pooled analyses of these trials reported no serious adverse events. As with any medical procedure, risks depend on the child’s health and the protocol used, and Dr. Jiménez reviews them with each family.
What Stem Cell Therapy for Autism Is Not
- It is not a cure for autism.
- It is not a replacement for behavioral, speech, occupational, or educational therapies.
- It does not come with guaranteed results.

Frequently Asked Questions About Stem Cell Treatment for Autism
No. Stem cell therapy for autism is investigational and should never be described as a cure. At most, it is considered a supportive therapy that may help certain symptoms in some children, alongside established therapies.
The largest randomized trial, involving 180 children, found that cord blood infusion was safe but did not improve social communication across the full group. Meta-analyses report improvements on several rating scales, but study sizes are small and methods vary, so the evidence remains limited.
Some families report meaningful changes, and those experiences matter. However, individual stories cannot predict another child’s response, because children keep developing and often receive other therapies at the same time. Controlled studies provide the most reliable evidence.
In clinical trials, reported side effects included fever, hyperactivity, vomiting, headache, aggressiveness, and agitation during IV placement, and pooled analyses reported no serious adverse events. Dr. Jiménez reviews each child’s health history and the specific risks before making any recommendation.
Renovo’s protocols for brain-related and neurological conditions, including autism, use dental pulp stem cells, selected for their neurotrophic, neuroprotective, and immunomodulatory properties. Clinical research on these cells for autism is at an earlier stage than research on umbilical cord cells.
No. Stem cell therapy should never replace behavioral, speech, occupational, or educational therapies. Families who pursue regenerative treatment are encouraged to continue their child’s established supports.
At Renovo, stem cell–only pricing generally ranges from $2,100 to $9,900 USD. Neurological protocols are designed individually, and you receive a written quote after medical review.
