Abstract:
After murine fetal liver cells (FLC) were transfected with granulocyte-macrophage colony-stimulating factor (GM-CSF) gene by recombinant adenovirus and intrasplenically transplanted into allogeneic mice, the effects of GM-CSF gene-transfected FLC on the recovery of immune response inhibited by chemotherapy were observed. The number of CD4 cells and the ratio of CD4 /CDS cells from peripheral blood lymphocytes increased significantly. The cytotoxicity of the NK cells and the proliferation response of splenocytes to ConA, LPS elevated markedly, but the same results were not from bone marrow. These data demonstrated that intrasplenic transplantation of GM-CSF gene-transfected FLC could effectively accelerate the recovery of immune response after high-dose chemotherapy.
