title: Development and characterization of cell lines of normal mouse bladder epithelial cells and 2-acetylaminofluorene-induced urothelial carcinoma cells grown in monolayer tissue culture.
abstract: Normal urinary bladder epithelial cells and cells derived from 2-acetylaminofluorene-induced urothelial carcinomas from male Balb/c mice were grown in monolayer culture and were characterized. Cell lines of normal bladder epithelium were mononucleated, sheet-forming cells, with a modal chromosome number of 40. Bladder epithelial carcinoma cells induced by 2-acetylaminofluorene were polynucleate, relatively fast growing, grew in soft agar, demonstrated a higher cloning efficiency than normal cells and formed tumors when inoculated into syngeneic hosts. Differences in morphology were recorded by photomicrography using phase optics and scanning electron microscopy.
