CSF1R and lymphoma: Reverse transcription-polymerase chain reaction (RT-PCR) revealed negative expressions of pax5, mb-1, and Il7R in the representative Ig-ganpTg mice lymphoma cell line B/M-2; however, we found positive expression of CD30 (Figure 3C) and strongly positive expression of c-fms, similar to that found in the control macrophage cell line J774.1.
