Establishment of two renal cancer cell lines

Two renal cell carcinoma (RCC) cell lines, JMSU2 and JMSU3, derived from the primary sites of mixed cell type and spindle cell type RCC, respectively, have been established and maintained for 31 and 22 months. Karyotypic analysis revealed human karyotypes with modal numbers of 84 and 55, respectivel...

520 |a Two renal cell carcinoma (RCC) cell lines, JMSU2 and JMSU3, derived from the primary sites of mixed cell type and spindle cell type RCC, respectively, have been established and maintained for 31 and 22 months. Karyotypic analysis revealed human karyotypes with modal numbers of 84 and 55, respectively. Consistent chromosomal abnormalities were 1p+, 3p-, 6q- or 8p- in the JMSU2 cells and 1p-, inv (5p + q-) or loss of sex chromosome in the JMSU3 cells. Electron microscopy revealed abundant glycogen granules, lipid droplets and microvilli. The JMSU3 cells transplanted to nude mice produced tumors with a spindle cell pattern similar to that of the original tumor. High concentrations of cytokines, such as interleukin-6 (145,000 pg/ml), interleukin-8 (35,300 pg/ml) and granulocyte-colony stimulating factor (6,340 pg/ml), were detected in the culture supernatant of the JMSU3 cells. Interleukin-1 beta (IL-1 beta) dose-dependently inhibited the proliferation of the JMSU2 and JMSU3 cells in culture. Tumor cytotoxic factor/hepatocyte growth factor (TCF/HGF) dose-dependently enhanced JMSU3 cell proliferation, but suppressed JMSU2 cell proliferation. These findings suggest that IL-1 beta and TCF/HGF have regulatory roles in the proliferation of RCC
