ABMSC mobilization and harvest
- For harvesting more ABMSC, ABMSC mobilization was induced by rhG-CSF (Gran○R), administered subcutaneously at a dose of 300μg daily for three consecutive days before open abdominal portal hypertension surgery.
- Bone marrow (160-200ml) of the patients was harvested from both posterior superior iliac according to standard procedures under local anaesthesia and was collected in a plastic bag containing heparin.
Open abdominal portal hypertension surgery
- Immediately after the harvest of ABMSC, the modified Sugiura procedure was performed for the patients who were assigned to the study group. The same surgical procedure was also performed for the control group (without harvest of ABMSC and ABMSC infusion).
ABMSC separation and infusion
- While performing the portal hypertension surgery, ABMSC was separated and purified in a class 10,000 clean laboratory. After fat and bony particles were removed by filtration, collected cells were moved to a cell-processing device. We used the reagent kit ([Patent Number] ZL 2006 1 0106875.5; [Number of Criteria Applicable] YZB/NING YIN 0008-2008; [Researcher and Developer] Wealthlin Science & Technology Inc., Canada; [Producer] Ningxia Zhonglianda Biotech Co., Ltd.). The reagents adopt the method of negative cells collection. Take the cells which intended to remove as target cells, and carry out the removal step-by-step. On the basis of this method, red blood cells, blood platelets, blood plasma will be completely removed with part of white cells and lymphocytes being remarkably removed as well while all the stem cells / progenitor cells are being well retained.
- The nucleated cell (white blood cell) count of final ABMSC was measured by an automated complete blood count instrument and flow cytometry analysis. The number of mononuclear cells was counted manually under a microscope by Wright-Giemsa stain method. CD34 positive cells were determined by flow cytometry analysis.
- The time of ABMSC separation and purification was 2.5-3 hours which had to be completed before the conclusion of portal hypertension surgery (3-3.5 hours). ABMSC was added to 10 ml saline and well mixed by shaking the vial gently. Before incision closure, the right gastric artery or right gastroepiploic artery was selected and a catheter was inserted. The catheter was pushed to reach the proper hepatic artery. The diameter of the catheter is 1.4mm, it is thin enough to easily been inserted to right gastric artery or right gastroepiploic artery (central venous catheterization, REF product NO.ES-04218, Arrow International, Inc.). The mixture of saline and AMBC was infused into hepatic artery at uniform speed for about two minutes. The catheter was removed after the ABMSCi. The puncture point of the right gastric artery was repaired using blood vessel suture or transfixed.
- Statistical analysis - Categorical data are presented as absolute values and percentages, whereas continuous data are summarized as mean and Standard Deviation. Statistical analysis was performed using t-test for paired or unpaired samples. Time courses of measurements of liver function parameters were analyzed by repeated-measures ANOVA. The analyses were performed using the SPSS 15.0 statistical package (SPSS Inc., Chicago, IL, USA). All statistical analyses were based on two-tailed hypothesis tests with a significance level of p< 0.05.
