Abstract
AIM: To demonstrate bone marrow stromal cells (BMSCs) can be used as an attractive target for genetic modification in the treatment of malignant diseases.
METHODS: Using a hamster model of biliary cancer, we investigated the therapeutic effects of interleukin-2 (IL-2) gene-modified BMSCs. Syrian golden hamsters were injected via the femoral vein with 5×105 cells of the KIGB-5 biliary cancer cell line (n=20). One week later, the hamsters were injected intraperitoneally with BMSCs containing Ad/hIL-2 and Ad/ΔE1, unmodified BMSCs, or RPMI only (control) and observed for 12 wk (n=5 /each group).
RESULTS: All hamsters treated with BMSCs containing Ad/hIL-2 survived with no evidence of the disease during this period. In contrast, hamsters in the other three groups showed disseminated metastases involving the lungs as early as 4 wk.
CONCLUSION: Ad/IL-2 therapy is effective in the treatment of biliary cancer.
