title: Lymphokine requirements for the development of specific cytotoxic T cells from single precursors.
abstract: A high cloning efficiency, filler cell-free culture system was developed for the growth of single murine cytotoxic T lymphocyte precursors (CTLp) and their differentiation into cytotoxic T lymphocytes (CTL). The system used nonspecific stimulation with phorbol ester and calcium ionophore in the presence of recombinant lymphokines. The optimal lymphokine combination was interleukin 2 throughout, together with interferon-gamma during the first 6 days and interleukin 6 during the last 2 days of culture. Under these conditions half of all CD4-CD8+ T cells became CTL clones. The CTL were CD4-CD8+CD3+ TcR alpha/beta+ and were derived from CD4-CD8+Pgp-1- precursors.
