1.Repeated transfection of the human hepatocyte growth factor (HGF) CDNA into skeletal muscle inhibited apoptosis of intestinal epithelial cells and donor T-cell infiltration into the liver, thereby ameliorating the enteropathy and liver injury caused by acute graft-versus-host disease (GVHD).2.HGF gene transfection suppressed IFN-y and TNF-a expression the intestine and liver and decreased the serum IL-12.3.Extramedullary hematopoiesis by donor cells was increased, and the survival rate of GVHD mice was improved by HGF gene transfection.4.HGF gene transfection did not affect donor T cell responses to host antigens (mixed lymphocyte reaction, CTL activity), thereby promoting leukemia-free survival of GVHD mice (HGF gene therapy separated acute GVHD from graft-versus-leukemia effects).5.HGF gene transfection promoted immune reconstitution by hematopoietic stem cell-derived donor T cells.

1.将人肝细胞生长因子（HGF）CDNA重复转染到骨骼肌中，抑制肠上皮细胞凋亡和供体T细胞向肝脏的浸润，从而改善急性移植物抗宿主病引起的肠病和肝损伤。 GVHD).2.HGF基因转染抑制肠和肝中IFN-γ和TNF-a的表达并降低血清IL-12.3.髓外供体细胞的造血能力增加，转染HGF基因提高GVHD小鼠的存活率。 4.HGF基因转染不影响供体T细胞对宿主抗原的反应（混合淋巴细胞反应、CTL活性），从而促进白血病的无GVHD小鼠的存活率（HGF基因治疗将急性GVHD与移植物抗白血病效应分开）。5.HGF基因转染促进造血干免疫重建细胞来源的供体 T 细胞。
