title: In vivo synchronization of haemopoietic stem cells with hydroxyurea.
abstract: Four injections of hydroxyurea 1 mg/g body weight, given to normal mice 31, 24, 10 and 7 h before sampling bone marrow, reduced CFU-S content of femoral marrow to 30% of normal in Balb/c female and to 10% of normal in C57 B1 male mice. Over 80% of the surviving CFU-S were in the S phase of cycle, as judged from their sensitivity to killing by hydroxyurea or ARA-C.
