- Participant has a parent who spends four or more hours a week with the participant, who is able and willing to participate in study visits and interim surveys and interviews
- Informed consent of the participant and parent (participants must have legal authority regarding their own medical care and a parent or legally authorized representative may not consent on their behalf)
- Exclusion Criteria
- General:
- Review of medical records indicates ASD diagnosis and IQ \> 70 unlikely.
- Known or suspected diagnosis of any of the following coexisting psychiatric conditions: bipolar disorder, schizophrenia, Tourette syndrome, and/or any co-occurring psychiatric disorder that the investigator believes would interfere with accurate completion of study instruments and/or current (within the past year) evidence of suicidality as assessed by an interview with participant and/or parent which includes the Columbia Suicide Severity Rating Scale, and a review of responses on the Behavioral and Symptom Identification Scale (BASIS-24).
- Screening data or in-person evaluations suggest that participant would not be able to comply with the requirements of the study procedures as assessed by the study team
- Parent and/or participant is unwilling or unable to commit to participation in all study-related assessments, including protocol follow up
- Sibling is enrolled in this (Duke AIMs) study
- Genetic:
- Records indicate that the participant has a known genetic syndrome such as (but not limited to) Fragile X syndrome, neurofibromatosis, Rett syndrome, tuberous sclerosis, PTEN mutation, cystic fibrosis, muscular dystrophy or a genetic defect definitively known to be associated with ASD
- Known pathogenic mutation or copy number variation (CNV) associated with ASD (e.g., 16p11.2, 15q13.2, 2q13.3)
- Infectious:
- Known active CNS infection
- Evidence of uncontrolled infection based on records or clinical assessment

- Coexisting medical condition that would place the participant at increased risk for complications of study procedures
- Concurrent genetic or acquired disease or comorbidity(ies) that could require a future stem cell transplant
- Significant sensory (e.g., blindness, deafness, uncorrected hearing impairment) or motor (e.g., cerebral palsy) impairment
- Impaired renal or liver function as determined by serum creatinine \>1.5mg/dL or total bilirubin \>1.3mg/dL, except in participants with known Gilbert's disease

- Current pregnancy and unwillingness to use adequate birth control for 3 months after the final study product infusion.
- Current/Prior Therapy:
- a. Availability of a banked, qualified autologous cord blood unit or parent deferred use of qualified, autologous cord blood unit b. History of prior cell therapy c. Current or prior use of IVIG or other anti-inflammatory medications with the exception of NSAIDs d. Current or prior immunosuppressive therapy i.
