By establishing rat transplantable tumor lines and cultured cell lines, the characteristics of neoplastic cells and pathobiological nature of the original cells have been investigated histopathlogically, immunohistochemically and molecular pathologically, and the mesenchymal differentiation and relevant growth factors have been clarified using the mesenchymal tumor lines established as pluripotential stem cells. Additionally, by establishing rat models of chemically-induced hepatic and renal fibrosis, the complicated pathogenesis of intractable diseases has been investigated with regards to heterogeneous functions of myofibroblasts and macrophages. These animal models contribute to studies on biomedical sciences, and become useful tools for evaluation system of medical drug development.
