title: CFU-GM and T cell subsets in young red cell collections.
abstract: Young red cells (YRBCs) prepared using cell separators contain large numbers of white cells. The absolute numbers and percentages of different lymphocyte subsets and progenitor cells in YRBC collections were assessed before and after filtration through two white cell filters. It was found that the filters do not take up or selectively allow through any one lymphocyte subset and that the absolute number of T cells and progenitor cells in YRBC collections after filtration is less than that in normal donor blood.
