. The proliferation rate of haemopoietic stem cells (CFU‐s) was followed after sublethal total body irradiation with 1.5 Gy. The [ 3 H]‐thymidine suicide technique was used to measure the CFU‐s proliferation rate. The measurements extended from 10 min after irradiation up to 21 days. The CFU‐s did not enter the DNA synthesis period (S‐phase) shortly after irradiation, as had been previously suggested, but did so only with a delay of 14–16 hr. A large scatter of results was explained by an oscillatory pattern in CFU‐s proliferation. The CFU‐s prepared for cell division in synchronized waves, with a period of 20–22 hr.
