| Outline of Final Research Achievements |
Various immune cells exist in the lymph node tissue, which is the main site of lymphoma lesions. In this study, we demonstrated the presence of mesenchymal stromal cells, which are recognized as one of the regulatory immune cells, in lymph node tissue. They have distinct biological characteristics from bone marrow-derived mesenchymal stromal cells, using a combination of cell culture and immunohistochemical and gene expression analyses. Furthermore, we showed that pharmacological stimulation can suppress the growth-supportive ability of lymphoma cells by mesenchymal stromal cells.

| Academic Significance and Societal Importance of the Research Achievements |
悪性腫瘍であるリンパ腫において腫瘍微小環境を標的とした薬物治療が有効であることの概念実証を示したことに学術的意義がある．わが国のガン統計によると，リンパ腫死亡者数は年間1万人以上で増加の一途をたどっており，薬物療法の基盤開発を通したがん対策の観点から社会的意義がある．
