Abstract | The main pathogenic event caused by Schistosoma mansoni infection is characterized by a granulomatous inflammatory reaction around parasite eggs and fibrosis in the liver. We have previously shown that transplantation of bone marrow cells (BMC) promotes a reduction in liver fibrosis in chronically S. mansoni-infected mice. Here we investigated the presence and phenotype of bone marrow-derived cells in livers of S. mansoni-infected mice. During the chronic phase of infection, C57BL/6 mice had an increased number of circulating mesenchymal stem cells and endothelial progenitor cells in the peripheral blood when compared to uninfected controls. In order to investigate the fate of BMC in the liver, we generated bone marrow chimeric mice by transplanting BMC from transgenic green fluorescent protein (GFP) mice into lethally irradiated wild-type C57BL/6 mice. S. mansoni-infected chimeric mice did not demonstrate increased mortality and developed similar liver histopathological features, when compared to wild-type S. mansoni-infected mice. GFP(+) bone marrow-derived cells were found in the liver parenchyma, particularly in periportal regions. CD45(+)GFP(+) cells were found in the granulomas. Flow cytometry analysis of digested liver tissue characterized GFP(+) cells as lymphocytes, myeloid cells and stem cells. GFP(+) cells were also found in areas of collagen deposition, although rare GFP(+) cells expressed the myofibroblast cell marker α-SMA. Additionally GFP(+) endothelial cells (co-stained with von Willebrand factor) were frequently observed, while BMC-derived hepatocytes (GFP(+) albumin(+) cells) were sparsely found in the liver of chimeric mice chronically infected with S. mansoni. In conclusion, BMC are recruited to the liver during chronic experimental infection with S. mansoni and contribute to the generation of different cell types involved, not only in disease pathogenesis, but possibly in liver regeneration and repair | pt_BR |
