this investigation was undertaken , firstly , to provide information on whether the normal counterparts of high grade lymphoma cells ( e.g . centroblasts , immunoblasts ) ever express more than one light or heavy chain ( as has been noted in the past for lymphomas ) and also , secondly , to seek evidence of intraclonal 'switching ' from cytoplasmic igm to cytoplasmic igg expression .
