using a novel flow cytometric assay ( brdu/hoechst flow cytometry ) for the visualization and quantitation of cell activation and cell progression through multiple cell cycles we show that ( 1 ) resting mononuclear cells from human venous blood respond to polyclonal activation in a highly asynchronous fashion , as some of these cells enter their first cell cycle as early as 30 and as late as 80 hrs after exposure to the mitogen ;
