Safety and Efficacy Study of Peripheral Blood Mononucleated Cells for Treatment of Liver Cirrhosis

G-colony stimulating factor (5ug/kg/day)will be administered subcutaneously to three patients with liver cirrhosis of this arm.

G-colony stimulating factor (5ug/kg/day)will be administered twice subcutaneously for 3 days to three patients with liver cirrhosis of this arm. On the day 4th, leukapheresis will be done to collect peripheral blood mononucleated cells. And then we are going to infuse the collected peripheral blood mononucleated cells of their own through the portal vein of each patients under ultrasonographic guidance.
