The cell cycle kinetics of bladder urothelial cells regenerating after partial cystectomy were investigated in 96 female Wistar rats using the percentage labelled mitoses method. In the area of resection a mean cell cycle time (TC) of 15 h was determined. The DNA synthesis phase (TS) lasted 6 h and the premitotic-postsynthetic phase together with the mitosis phase (TG2 + M) 1.5 h, thus giving a presynthetic-postmiotic phase (TG1) of 7.5 h. Similar values were found for the urothelial cells in the stump: the mean cycle time measured 14 h, the TS-phase 6 h, the TG6 + M-phase 2 h and the TG1-phase 6 h. These data are discussed with respect to known cell cycle parameters of bladder urothelium regenerating in response to cytotoxic agents and of neoplastic urothelial cells. The reported findings provide a basis for further investigations using weak carcinogens and threshold doses of potent carcinogens to test the working hypothesis that stimulation of proliferation following partial cystectomy is capable of initiating, accelerating and/or potentiating carcinogenic cell transformation in the urinary bladder.
