Features of iMycEμ-2 cells. A, Cytofuge specimen stained according to May-Grünwald-Giemsa. A bi-nucleated cell (arrow) and a cell undergoing mitosis (arrowhead) adjoin neoplastic plasmablasts containing the typical paranuclear hof of neoplastic plasmablasts and plasma cells (asterisk). B, B-cell surface marker expression determined by FACS (green lines) compared to isotype controls (purple histograms). C, Western analysis of Myc protein using β-actin as loading control. D, RT-PCR analysis of Myc and MycHis mRNA compared to β-actin message.
