Lectin-induced lymphocyte stimulation in pigs--a kinetic study of NORs

Early reactions of rRNA-cistrons in lectin-stimulated PBL cultures of domestic pigs are shown. Interphases showing 3 or more clusters of stained areas were attributed mainly to cells after first division. Clear differences are shown between PHA- and ConA-induced NOR-expression patterns compared to the patterns in PW-stimulated cultures.
