چکیده انگلیسی
Malignant fibrous histiocytoma (MFH) is regarded as an undifferentiated pleomorphic sarcoma with unproven histogenesis. We investigated pathobiological characteristics of a rat MFH cell line (MT-9). Immunocytochemically, MT-9 cells and MT-9-induced tumours reacted to vimentin, A3 (rat MFH cell-specific antibody), macrophage markers and α-SMA (myofibroblastic marker), indicating that MT-9 showed both histiocytic and (myo)fibroblastic features. Adipogenic supplement-added MT-9 showed increased accumulation of lipid droplets. Addition of BMP-2 or osteogenic supplement to MT-9 enhanced osteoblastic markers (ALP activity, osteocalcin mRNA expression and calcification). TGF-β1-treated MT-9 revealed increased numbers of α-SMA-immunopositive cells, and enhanced protein levels of α-SMA and fibronectin, indicating myofibrogenesis. In rat tissues, A3 labelled with immature mesenchymal and perivascular cells in foetuses and neonates, and with marrow stem cells in adults. c-kit mRNA expression was seen in bone marrows and MT-9. Collectively, progenitors of MFH should be sought in lineage of marrow stem cells capable of differentiating into mesenchymal cells.
