Electronmicroscopy of hybridoma clones derived by fusing BALB/c mouse spleen cells with P3U1 mouse plasmacytoma cells to generate monoclonal antibodies against human sarcoma antigens, revealed the presence of large number of viral particles. These particles were also seen budding from the cell surfaces. The intracytoplasmic particles were intracisternal and resembled type-A oncornavirus, while the budding and extracellular forms, with a centrally located nucleoid, resembled mature type-C oncornaviruses. Cells of the parental P3U1 palsmacytoma cell line and of the NS-1 myeloma cell line contained morphologically identical viral structures. The scientific and medical communities engaged in hybridoma research should be alert to the possible presence of viruses in hybridomas and their products. The question is raised as to whether it is safe to use mouse monoclonal antibodies for clinical purposes, both diagnostic and therapeutic. [ABSTRACT FROM AUTHOR] |
