Cells started to migrate out of the crypts shortly after plating them on NRK feeder layers. Some of the crypts fell apart during the isolation procedure. whereas the vast majority of them did it within I to 2 Ill after plating. The cells proliferated extremely slowly but continuously over a period of 4 mo and were epithelial because they expressed cytokeratin 19 and were stained by crystal violet at pH 2.8. In conclusion, the experimental system described ill this study allows to maintain rat colon epithelial cells for up to 4 mo in culture and can be used to Study the effects of a variety of tumor-modulating factors on growth and gene expression of normal colon epithelial cells in vitro}, language = {en} } @article{FuchsTeubnerSteinberg2004, author = {Fuchs, J. and Teubner, Wera and Steinberg, Pablo}, title = {The resistance of intestinal epithelial cells towards the transforming activity of 2-hydroxyamino-1-methyl-6- phenylimidazo[4,5-B]pyridine is accompanied by glutathione S-transferase induction}, issn = {0028-1298}, year = {2004}, language = {en} }
