| Outline of Final Research Achievements |
Visualizing the function of donor cells after allogeneic hematopoietic stem cell transplantation (HSCT) will enable understanding of the process of graft-versus-host disease (GVHD). In this study, we visualized the proliferation and apoptosis of green fluorescent protein protein (GFP) donor cells using immunofluorescence staining and in vivo fluorescence imaging. Immunofluorescence staining revealed that a large fraction of donor cells were cell proliferation marker, Ki-67 positive and a few host but not donor mononuclear cells were apoptotic cell marker, cleaved Caspase-3 positive in the secondary lymphoid organ at early phase after HSCT. We could not visualize apoptotic cell using in vivo fluorescence imaging. However, it is very important for visualizing cellular proliferation and apoptosis in vivo to understand the process of GVHD.
