To determine whether donor-derived fibroblasts originate from bone marrow, we used an animal model of chronic graft versus host disease (cGVHD). (Zhang Y, J Immunol, 2002)To examine the cellular sources of donor-derived fibroblasts in cGVHD recipients, we analyzed mesenchymal stem cells (MSC) (Morikawa S, J Exp Med. 2009) and hematopoietic stem cells (HSC) (Matsuzaki Y, Immunity 2004) from bone marrow. We performed the prospective study using freshly isolated MSCs from donor and HSC from recipient. This is a MSC alone mismatched transplantation. In contrast, MSCs from recipients and HSCs from donor used as a syngeneic MSC transplantation.In mismatched MSC transplantation, mallory staining of lacrimal gland, liver and salivary gland revealed progressive fibrosis, similar to whole bone marrow transplantation. In contrast, excessive fibrotic areas were scarcely detected 3 and 8 weeks after syngeneic MSC transplantation. When GFP B10.D2 mice were used as donors, GFP+MSCs were found residing in cGVHD fibrotic lesion such as the lacrimal gland, skin and intestine. These results suggest that donor MSCs are partially a source of HSP47+fibroblasts in cGVHD fibrotic tissue. In addition, these results suggest that donor MSCs alone are sufficient to induce cGVHD fibrosis.

为了确定供体来源的成纤维细胞是否来源于骨髓，我们使用了慢性移植物抗宿主病（cGVHD）的动物模型。（Zhang Y，J Immunol，2002）为了检查cGVHD受体中供体来源的成纤维细胞的细胞来源，我们分析了来自骨髓的间充质干细胞（MSC）（Morikawa S，J Exp Med.2009）和造血干细胞（HSC）（Matsuzaki Y，Immunity 2004）。我们使用从供体新鲜分离的MSC和从受体新鲜分离的HSC进行了前瞻性研究。这是一种单独的MSC不匹配移植。异基因MSC移植组大鼠泪腺、肝脏和唾液腺马洛里染色显示进行性纤维化，与全骨髓移植组相似。相反，在同基因MSC移植后3周和8周几乎没有检测到过度的纤维化区域。当使用GFP B10.D2小鼠作为供体时，发现GFP+ MSC驻留在cGVHD纤维化病变如泪腺、皮肤和肠中。这些结果表明，供体MSC是cGVHD纤维化组织中HSP 47+成纤维细胞的部分来源。此外，这些结果表明，供体MSC单独足以诱导cGVHD纤维化。
