Monoclonal cytolytic T-cell lines.

Abstract
Monospecific cloned cytolytic T[thymus derived]-lymphocyte lines [from mice] were created utilizing T-cell growth factor. The clones retained their cytolytic specificity after prolonged culture and monospecific function was demonstrated by subcloning procedures. Detailed studies of the phenotypic and functional characteristics of monospecific, homogeneous, cytolytic T [thymus-derived] lymphocytes will be possible.
