Aberrant nuclear morphology in the mouse myeloma SP2/0 cell line.
The mouse myeloma SP2/0 cell line when grown in supplemented Dulbecco's modified Eagle's media spontaneously produced aberrant nucleated cells which increased in frequency with cell culture age. These cells underwent cytological changes associated with apoptosis, that is, the condensation of chromatin followed by karyorrhexis and the production of small apoptotic bodies. Aberrant cells were induced by media changes, centrifugation, and temperature shocking. The rapid induction of aberrant cells by a media change suggests that the mechanism of fragmentation was not associated with cell division.
