Quantitative studies on T cell diversity. II. Determination of the frequencies and Lyt phenotypes of two types of precursor cells for alloreactive cytotoxic T cells in polyclonally and specifically activated splenic T cells

Two different limiting dilution systems have been applied to compare precursor frequencies of alloreactive cytotoxic T cells (CTL-P) in the polyclonally and specifically activated lymphocyte populations and in selected Lyt T cell subsets. Both systems make use of T cell growth factor for T cell expa...
