MEFV expression in various cells.

RT-PCR analysis was performed on total RNA with the use of common and normal primers designed from exon 10 as described in “Materials and methods.” The size of the amplified MEFV fragment was 200 bp. Lane 1: Normal human neutrophils. Lane 2: HL-60 cells, uninduced. Lane 3: Retinoic acid–induced HL-60 cells after 5 days incubation. Lane 4: Peritoneal fibroblasts, third passage.
