Autoradiographic evaluation of the cell cycle parameters of the various cells categories of the parotid, submandibular and sublingual glands of the suckling rat.
The evolution of the percentage of radioactive mitosis after a single thymidine-H3 injection, was determined for the various cell categories of the parotid, submandibular and sublingual glands of rats at 5th and 15th day of postnatal age. Estimates of the lengths of the S and the G2 + M/2 phases of the cell cycle were thus obtained, and averaged 9.8 and 2.7 hours, respectively, with extreme values of 9.3-11.2 and 1.6-3.2 hours.
