Анотація: A promising source for cell therapy are multipotent mesenchymal stromal cells (MMSC), whose biological properties can change at immune dysfunction of central genesis. The purpose of the study is to investigate the ability of murine bone marrow-derived MMSC to colony formation, directed differentiation and immunosuppressive effect at different content of serum thymic factor (thymulin) in the body and in the cell culture in mice of different strains. Materials and methods. MMSCs cultures were obtained from the bone marrow of FVB/N and 129/Sv mice. We performed the study of clonogenic ability of MMSCs, phenotyping, assessment of the osteogenic and adipogenic potential, estimation of immunomodulating properties of MMSCs after thymectomy or addition of the thymulin in the culture in vitro. Results. It was found that the level of thymulin in the control mice of the FVB/N strain is higher than in 129/Sv mice. The ability of bone marrow progenitor cells to colony formation in control and thymectomized mice depends on their genotype. When adding thymulin at concentrations of 1 ng/mL and 10 ng/mL to the bone marrow cells culture of both strains thymectomized mice, the change in the number of colony-forming unit fibroblasts was observed only with the addition of a high dose of the hormone. Thymectomy in FVB/N mice leads to an increase in the differentiation of MMSCs in the osteogenic direction and to a decrease in adipogenic differentiation, which is restored after adding thymulin to the cell culture. In thymectomized 129/Sv mice, there was a decrease in osteogenic differentiation and recovery after incubation of cells with thymulin. The immunosuppressive effect of bone marrow MMSCs was established in mice of both strains. In this case, strain-dependent differences in this effect are manifested in the degree of immunosuppression. Conclusion. The ability of bone marrow MMSC of the FVB/N and 129/Sv mice to colony formation, directed differentiation and immunosuppressive effect at different content of thymulin in the body or in cell culture is related with the thymus function and changes after thymectomy. The response of the bone marrow MMSCs to the thymectomy depends on the genotype of the mice. It has been shown that thymulin has a recover effect on the reduced clonogenic and osteogenic potential of the bone marrow-derived MMSCs in mice of both strains and the adipogenic potential in 129/Sv mice.
