RT-PCR analysis of the RNA sequence transcribed across the site of recombination in the t(7;17)(p15;q21). Ethidium bromide-stained agarose gel of RT-PCR products amplified from total RNA of normal tissues and the four low-grade ESSs known to carry the translocation. The source of fibroblasts and normal endometrium was the same as that in Fig. 3; the normal myometrium was obtained from the same specimen as the endometrium.
