Could your own fat cells help heal a traumatic brain injury?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. adults between 18 and 55 years of age 2. documented head injury with functional neurological damage to the central nervous system unlikely to improve with present standard of care approaches 3. a Glasgow Outcome Scale-Extended (GOS-E) score \> 2 and ≤ 6 4. onset or diagnosis of the injury or disease process greater than 6 months 5. ability to obtain consent from the subject of their legally authorized representative (LAR) 6. ability to speak English or Spanish \*required for validated neurocognitive outcome testing) - Exclusion Criteria: 1. known history of: 1. intellectual deficiency or psychiatric conditions likely to invalidate our ability to assess changes in cognition or behavior, 2. recently treated infection, 3. renal disease or altered renal function (screening serum creatinine \> 1.5 mg/dL), 4. hepatic disease or altered liver function (screening SGPT \> 150 U/L or T. Bilirubin \>1.3 mg/dL), 5. cancer, 6. immunosuppression (screening WBC \< 3, 000 cells/ml), 7. HIV+, 8. chemical or ETOH dependency that in the opinion of the investigator would preclude participation in the study, 9. acute or chronic lung disease requiring significant medication, oxygen supplementation, or mechanical ventilation, 10. bleeding disorders including immune-mediated heparin-induced thrombocytopenia, 11. known sensitivity to heparin, Lovenox, and pork products, 12. individuals with mechanical prosthetic heart valves. 13. individuals who have received a stem cell treatment. 2. Normal brain CT/MRI exam 3. Spinal deformity, spinal surgery (including repeated epidural or spinal punctures), or spinal cord injury diagnosed by CT/MR or clinical exam 4. diagnosed with a genetic or metabolic disorder related to the neurologic condition 5. other acute or chronic medical conditions that, in the opinion of the investigator, may increase the risks associated with study participation 6. for women of child bearing potential, a positive pregnancy test at the screening visit, or, for both women and men, unwillingness to comply with acceptable methods of birth control during the study 7. participation in a concurrent interventional study 8. inability to undergo the diagnostic tests (PET/DT-MRI) or unwilling/unable to cooperate with the diagnostic tests and outcome assessments 9. unwilling or unable to return for follow-up study visits -
