The meeting brought together immunologists study- ing clonal T-cell development in man and mouse in various in vitro systems at the cellular as well as molecular level. It was an attempt to provide an overview of the current research interests of groups working on (a) the developmen- tal potential of in vitro expanding primary T-cell clones (investigated using limiting dilution analysis) and cloned T -cell lines established in...
