surface phenotyping of the progenitor cells responsible for repopulation showed that lyt-2- cells were required for helper cell regeneration and that lyt-2+ cells acted as progenitors only for the cytotoxic lineage , contrary to earlier speculation that the splenic lyt-1+ 2+ ( ly-123 ) pool included cells antecedent to both effector lineages .
