| Abstract | ||
| The pristane oil induced mouse plasmacytoma (MPC) model is the most widely used and accepted model and has provided the most data on plasmacytomagenesis so far. Plasmacytoma were induced in Swiss mice by the intraperitoneal injection of pristane (2,6,10,14-tetra-methylpentadecane) after a latent period of 5-6 months where the mice developed ascites tumors. Aspirated cells were cultured in tissue culture flasks and kept under observation and further passaged to obtain continues cell line. Peritoneal exudate cells were prepared from pristane-treated and control uninjected mice during the course of a 6-month period, and these cell suspensions were studied by means of cytology, histology and Immunohistochemistry methods to identify the plasmacytoma specific markers and the genetic changes. Results showed induction of the tumor in 50% of injected mice and the new cultured cell line were negative for Retinoblastoma (RB) and epidermal growth factor receptor (EGFR) | ||
