Limiting dilution analysis of alloantigen-reactive T lymphocytes. VI. Ontogeny of cytolytic T lymphocyte precursors in the thymus.

Abstract

The ontogeny of development of precursors of cytolytic T lymphocytes (CTL-P) in the murine thymus has been investigated. Fetal or newborn thymocytes harvested from C57BL/6 mice were cultured with irradiated allogeneic (DBA/2) spleen cells in limiting dilution mixed leukocyte microcultures and assayed for cytotoxicity against 51Cr-labeled P-815 (DBA/2) tumor… (More)
