Effect of autologous mesenchymal pluripotent stem cells transplantation on liver microcirculation in rats with experimental liver cirrhosis

Aim. To study the effect of autologous bone marrow pluripotent stem cells transplantation on liver microcirculation in experimental model of liver cirrhosis.

Methods. 43 white Wistar male rats with body weight of 150-180 g aged at least 3 months were used, in which autologous pluripotent mesenchymal stromal cells transplantation was performed. Considering the animals mortality at the cirrhosis modeling stage, which was 9.3% (4 out of 43 rats), the first group included 19 rats in which stromal cells were transplanted into the portal vein; in the second group (20 rats) the cells were injected into the common hepatic artery. Liver microcirculation was studied using laser Doppler flowmetry and wavelet analysis. Examinations were performed during the operation prior to autologous pluripotent mesenchymal stromal cells transplantation in rats with experimental liver cirrhosis, as well as on the 8th week of treatment.

Results.In modeled liver cirrhosis, the microcirculation index was decreased by 24.5% (p

Conclusion. The repeated studies of microcirculation based on laser Doppler during the treatment of animals with experimental liver cirrhosis indicates the advantages of intra-arterial autologous multipotent mesenchymal stromal cells transplantation.
