The purpose of this study is to analyze the safety and efficacy of mesenchymal stem cell transplantation through percutaneous injection in patients with chronic spinal cord injury.
This is a pilot, open, phase I study, in a prospective cohort. The study population will consist of 5 patients who had spinal cord injury for at least 6 months, with complete paraplegia. A practitioner, a neurosurgeon and a nurse will review the medical records of patients to determine the presence / absence of inclusion / exclusion criteria. If the patient is a potential candidate for the study, an interview will be scheduled with the patient to review and confirm his/her eligibility. If the clinical eligibility is confirmed, the patient will undergo psychosocial evaluation to determine the degree of emotional equilibrium and conditions for participation in the study. Patients will undergo a series of clinical and neurological evaluations and will also be submitted to the following procedures: * Cell blood count; * Biochemical analysis (measurement of electrolytes - sodium, potassium, magnesium); * Renal function tests (urea and creatinine); * Liver function tests; * Coagulation profile; * Metabolic profile (glucose, total cholesterol and fractions); * Urine summary and culture; * Serology required for blood transfusion and marrow transplant in Brasil; * Electrocardiogram; * Chest X-Ray, X-ray of knees; * Bone densitometry; * Urodynamic studies; * Somatosensory evoked potential; * Computed tomography of thoracic and lumbar spine; * MRI of the thoracic and lumbar spine. Also as part of the preoperative evaluation, the patients will respond to questions from the SF (Short Form) -36 questionnaire (for assessment of quality of life) and the questionnaires for the assessment of neuropathic pain. Clinical follow-up will be kept for patients who suspend their participation in the study for any adverse event and / or laboratory abnormality, or for the patient's own desire, following insurance protocols. In addition to the clinical and surgical follow-up, specific medical care will be offered to patients who experience adverse events, until stabilization of the patient, even if the target date for completion of the study has been exceeded. The candidates included in the study will be asked to voluntarily participate and give their informed written consent. Patients will be recruited for a minimum period of 06 months to follow up with additional laboratory and clinical examinations.

Mesenchymal stem cell transplantation through percutaneous injection.
Hospital São Rafael
Salvador, Estado de Bahia, Brazil
Magnetic resonance imaging
After the transplantation of the cells, patients will be followed up by clinical examinations and will perform laboratorial and radiological exams, in order to search for complications of the procedure.
Time frame: Six months
Sensitivity and motor strength on the inferior limbs
AIS (ASIA Improvement Scale) degree on the ASIA score will be assessed in order to evaluate sensitivity and motor strength on the inferior limbs.
Time frame: Six months
Improvement in urological function
The patients will undergo urodynamic study to evaluate urological improvements.
Time frame: Six months
Improvements in sensorial mapping and neuropathic pain
The patients will be submitted to specific questionnaires and clinical examinations in order to evaluate improvements in sensorial mapping and neuropathic pain.
Time frame: Six months
