EFFICACY OF STEM CELL USE IN THE TREATMENT OF LIVER CIRRHOSIS (EXPERIMENTAL STUDY)

Abstract

Rationale. The need to find the most effective ways to restore liver function in cirrhosis. Goal. To evaluate the effectiveness of using cellular technologies in liver cirrhosis in an experiment.Materials and methods. The experiment included 132 individuals of c57black mice aged 12 to 18 weeks. All individuals are divided into 5 groups (30 individuals in group’s №1– №3, №5 and 12 individuals in group №4). Individuals of group 5 were removed from the experiment before it began in order to determine the normal weight of the liver and spleen. A model of liver cirrhosis was created for individuals of groups 1– 4. Group 4 individuals were removed from the experiment 30 days after the model was formed to confirm the presence of liver cirrhosis. Individuals of group 1 were given intravenous stem cells. Individuals of group 2 were intraportally injected with stem cells. Individuals of group 3 were not injected with stem cells. Changes in all three groups were evaluated 30 days after cell therapy.Results. Against the background of cell therapy, the greatest decrease in liver mass is observed in group 2 (intraportal administration of stem cells), where the liver mass exceeds normal values by 7%. In second place is group 1 (intravenous administration of stem cells), where the liver mass is higher than normal by 17%. In group 3, the liver mass exceeds normal values by 25.3%. The spleen mass 30 days after the application of cell technologies in the second group differed from normal values by 0.01 g; in group 1-by 0.06 g; in group 3-by 0.1 g. The level of total protein 30 days after the introduction of stem cells in group 1 increased by 5.9%; in group 2 by 28.8%; in group 3 by 1.1%. Albumin levels increased by 11% in group 1, 33.8% in group 2, and remained unchanged in group 3. The ALT level in group 1 decreased by 32.3%, in group 2 by 48.1%, and in group 3 remained unchanged. The AST level decreased by 7% in group 1, by 25.9% in group 2, and remained unchanged in group 3. Indicators of alkaline phosphatase decreased by 3.9% in group 1, by 14.3% in group 2, and did not improve in group 3.Conclusion. The use of cellular technologies in liver cirrhosis contributes to a faster recovery of liver function when intraportal introduction of cellular structures.
