T-Lymphocyte–Mediated Granulopoietic Failure

Abstract
To identify patients with T-lymphocyte–mediated granulopoietic failure, we compared clonal growth of unfractionated bone-marrow cells with that of autologous marrow cells from which T lymphocytes had been removed, in a group of 234 patients. We also attempted to identify prednisone-responsive patients by culturing both unfractionated and T-depleted cells with and without glucocorticoids in vitro.
