| Research Abstract |
This study was designed to investigate the suppressive effect of HGF(hepatocyte growth factor) on GVHD(graft-versus-host disease) in nonmyeloablative preparative regimen bone marrow transplantation as the treatment of pancreatic cancer.
In original plan, the effect of HGF on GVHD suppression was determined by dose reduction of immunosuppressant agents. But it was thought to unable to determine whether the reduction of immunosuppressant agents was possible by HGF because of the deficiency of T cell and B cell.
So, we considered the laboratory model. We set the site of inplant of the cancer cell subcutaneous of the back of the SCID/B6 mouse. In this model, we determined the effect of HGF on GVHD and GVT effect.
After plantation of pancreatic cancer cells, bone marrow and lymphocytes of spleen were transplanted. And we determined the changes in the size of implanted tumor and GVHD effects on small intestine and liver.
Our data of GVT effect were scattering, and it was difficult to quantification of GVT effects. Although t is necessary to determine in more number of experimental model, it was confirmed that HGF may have possibilities to reduce the GVHD without reduction of GVT effect.
