REVIVE(Randomized Exploratory Clinical Trial to Evaluate the Safety and Effectiveness of Stem Cell Product in Alcoholic Liver Cirrhosis Patient)

If the participant voluntarily agrees to participate in the clinical trial before registration, the investigator conducts a screening test to evaluate the participant's suitability. A participant that satisfies all selection and exclusion criteria is assigned randomly to a test group (1-time or 2-time injection group) or control group (no-cell therapy group). Participants assigned to the 1-time injection group conduct cell therapy within 1 month after bone marrow aspiration. Before implementing cell therapy, implement hepatic artery catheterization which inserts a catheter into the hepatic artery through the right aorta femoralis and inject 5X107 autologous bone marrow-derived mesenchymal stem cells. Participants assigned to the 2-time injection group store 1-time injection amount of mesenchymal stem cells while being cultivated after sampled from the bone marrow, and will re-inject autologous mesenchymal stem cells within 1 month after first injection. Participants will make a total of 8 hospital visits on a 4-week interval after registration, and effectiveness and safety will be evaluated based on a fixed procedure on every visit.
