Cell therapy of comatose states.

We demonstrated that liquor from adult humans can maintain proliferative activity of cells of immature nervous tissue in vitro. The paper presents the results of a retrospective clinical study of the efficiency of cell therapy in the treatment of II-III degree comatose patients with severe brain injury. Cell suspension consisting of cells derived from immature nervous and hemopoietic tissues was injected into the recipient subarachnoidal space through a cerebrospinal puncture. The mortality in the study group was 8% vs. 56% in the control group. The 1.5-year follow-up demonstrated significantly better quality of life in patients receiving cell therapy in comparison with patients of the control group. Cell therapy proved to be ineffective for patients in a comatose state caused by hypoxic encephalopathy. The study demonstrated the efficiency of cell therapy in patients with severe brain injury during the acute period of the disease.
