Abstract
A new cell line (KMMโ1) was established from a subcutaneous plasmacytoma of a 62โyearโold male with multiple myeloma. Immunological studies indicated that cultured cells were derived from the same clone of myeloma cells in vivo: smeared cells were stained with fluoresceinconjugated globulin of antisera monospecific to lambdachain, and lambdaโchains in the cell extracts and in culture media were identical to the BenceโJones protein found in the patient's urine. The cell line grew in suspension with a doubling time of 36โ40 h and contained primitive plasmablastoid cells with prominent nucleoli and rough endoplasmic reticulum. Cells had the karyotype of 47, X, โY. lq+, โ2, +t(1:2) (cen:cen), +7, 12q+, 14q+, +mar and carried no EpsteinโBarr virusโdetermined nuclear antigen. Surface markers were as follows; E rosette (โ), IgG Fc receptor (โ), C3 receptor (โ), Sโlg (+), TdT (โ), asialoโGM, (โ). The reasons for the successful establishment of the myeloma cell line are discussed.
