Abstract:
Peripheral blood mononuclear cells stimulated either by diffusion chamber culture or by a high Con A concentration exhibit suppressive activity under conditions where no increase in cell number takes place. Instead an accumulation of large cells is observed which, according to their DNA contents, are classified as cells in the G2 phase of the cell cycle. By elutriation separation the suppressive activity is shown to be confined to this cell cycle phase.
