Abstract (original English)
To overcome the therapeutic limitations of malignant fibrous histiocytoma (MFH), we evaluated human adipose tissue-derived mesenchymal stromal cells (MSCs) that secrete tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on metastatic MFH. MFH is a highly malignant and metastatic type of sarcoma but surgical removal is the only effective method for treating MFH. MSCs are easily transduced to express a high level of transgene and can migrate toward cancer. For this reason, MSCs are a promising candidate for metastatic MFH therapies. In vitro sustainability of MSC-TRAIL against MFH-ino was analyzed by apoptosis assay. For preclinical study, anti-MFH effects of MSC-TRAILs were validated in murine models for local tumorigenesis and metastasis. Furthermore, a time-interval metastasis model of MFH was applied to confirm antimetastatic ability of MSC-TRAIL for preestablished metastatic MFH. We found that MFH-ino is highly susceptible to recombinant TRAIL and MSC-TRAIL, which selectively induce apoptosis via caspase-8 activation in vitro. Moreover, not only MFH-ino but xenograft explants were also significantly inhibited by MSC-TRAIL in local tumorigenesis. In particular, the metastatic ability of MFH-ino was considerably reduced by MSC-TRAIL in metastasis murine model, particularly for preestablished metastatic MFH. These results suggest that MSC-TRAIL is sufficiently effe
