Transplantation treatment of spinal cord injury patients.
The minimally manipulated cells from fetal nervous and hemopoietic tissues (gestational age 16-22 weeks) were subarachnoidally implanted into 15 patients (18-52 years old) with severe consequences of traumatic spinal cord injury (SCI) at cervical or thoracic spine level. The times after SCI were from 1 month to 6 years. Each patient underwent from one to four cell transplantations (CT) with various time intervals. In 11 of 15 cases, CT was combined with an operative partial disruption of a connective tissue cyst and with implantation into a spinal cord lesion of a spinal cord fragment together with olfactory ensheathing cells. Before CT the patients showed complete motor and sensory function disorder consistent with a grade A of SCI according to Frankel classification. With CT treatment, six patients improved their neurological status from A to C grade of SCI, exhibiting incomplete restoration of both motor and sensory function. The status of other five CT-treated patients became consistent with SCI grade B and was characterized by appearance of contracting activity in some muscles and incomplete restoration of sensitivity. The remaining four patients did not exhibit any clinical improvements. No serious complications of CT were noted. The results suggest a clinical relevance of the CT-based approach to treating severe consequences of SCI.
