چکیده

A technique for isolating and establishing long-term cultures of rat urinary bladder epithelium has been devised. Cells isolated and cultured by this method have been grown for 12 weeks without subculturing. Rat bladder epithelial cells require the addition of putrescine, spermine, and spermidine to attain maximum growth and long-term survival. Monolayer cultures have been subcultured and carried through five passages.

Enhancement of transformation in vitro of a nontumorigenic rat urothelial cell line by interleukin 6.

Chronic inflammation of the urinary tract is a significant risk factor for the development of bladder cancer. We have shown that acute and chronic inflammation induced by intravesical instillations of killed Escherichia coli strikingly enhances N-methyl-N-nitrosourea (MNU)-initiated rat bladder carcinogenesis. To test the hypothesis that cytokines released during inflammation may be involved in...

Hepatocyte growth factor is an invasion/migration factor of rat urothelial carcinoma cells in vitro.

Hepatocyte growth factor (HGF) plays an important role in the growth, progression and angiogenesis of various tumors. It is reported that patients with urinary bladder cancer have elevated levels of HGF in urine and that bladder cancer tissue contains an increased amount of HGF. Thus, the data suggest a functional role of HGF in urinary bladder cancer. We evaluated the mechanistic role of HGF i...

Transferrin as a Growth Factor for Rat Bladder Carcinoma Cells in Culture1

Using the heterotopically transplanted rat urinary bladder system, we previously showed that normal urine has a tumor-enhancing effect on carcinogen-initiated unit helium. In an attempt to isolate a urinary growthstimulating (tumor-enhancing) faclor(s), urine was first fractionated by Bio-Gel I'-100 column chromatography, and each fraction was tested for inducibility of ornithine decarboxylase ...

Transferrin as a growth factor for rat bladder carcinoma cells in culture.

Using the heterotopically transplanted rat urinary bladder system, we previously showed that normal urine has a tumor-enhancing effect on carcinogen-initiated urothelium. In an attempt to isolate a urinary growth-stimulating (tumor-enhancing) factor(s), urine was first fractionated by Bio-Gel P-100 column chromatography, and each fraction was tested for inducibility of ornithine decarboxylase (...
