Abstract:

Liver fibrosis (cirrhosis) is a consequence of chronic liver disease characterized by replacement of liver tissue by fibrosis, scar tissue and regenerative nodules (lumps that occur as a result of a process in which damaged tissue is regenerated), leading to loss of liver function. In our research we try to select a necessary conditions, dose and terms values to treat liver fibrosis (LF) with transplantation of allogeneic bone marrow mesenchymal stromal cells (MSCs) and evaluate the effectiveness of these techniques. LF was modeled on 5 groups of Wistar rats (n=90). In groups 1 ? 4 rats got different doses of MSCs at the different days during development of their disease. Group 5 served as a control (LF without MSCs). In all groups LF was detected already on 3 rd and 10 th days. In group 5 LF increased to 60-90 days, but stopped to grow more to 120 th day. Immunohystochemical studies revealed a two-phase dynamics both the development of LF and resorption of the connective tissue, especially expressed in group 2 (MSCs injection was performed twice, on 3 rd and 10 th days, total dose 5?10 6 ). Transplantation of MSCs for the LF promotes resorption of connective tissue in the liver, which has a two-phase dynamics. The most effective was the transplantation of MSCs at the early stage of development of LF in a dose of 5?10 6 cells. At the late stage of LF-development the effect of connective tissue resorption probably may be achieved by using of higher cell doses (10 million MSCs).
