内容記述 | Tumor-stromal interactions are important for the progression of malignant tumors. The purpose of the present study was to examine interactions of cholangiocarcinoma (CC) cells and stromal fibroblasts with respect to stromal-derived factor-1 (SDF-1) and transforming growth factor (TGF)-β1. Two cell lines of CC (HuCCT-1 and CCKS-1) and WI-38 fibroblast cell line were used for cell culture, and 12 CC tissue specimens for immunohistochemical studies. Invasion of CC cells was increased significantly by the supernatant from fibroblast cultures, but not by the supernatant from fibroblasts cocultured with CC cells. Expression of SDF-1 in cultured fibroblasts was downregulated by TGF-β1 treatment, and coculture with CC cells and anti-TGF-β1 neutralizing antibody restored the decreased SDF-1 expression, suggesting that TGF-β1 secreted from CC cells might have reduced the expression of SDF-1 by fibroblasts and might have reduced the increased invasion of CC cells induced by the supernatant from fibroblasts. Immunohistochemical expression of TGF-β1 in CC cells was focal or negative and that of SDF-1 was evident in stromal fibroblasts at the invasive front of CC. In conclusion, local mutual influence of TGF-β1 secreted from carcinoma cells and SDF-1 expressed by stromal fibroblasts may be involved in invasion of CC cells. © 2006 Japanese Society of Pathology. | |||||
