Spatial distributions of SINE and LINE elements in prospermatogonial nuclei. Frozen sections of E15.5 testis were stained with 4′,6-diamidino-2-phenylindole (DAPI) (A) and hybridized against Cy3-dUTP-labeled B1/B2 probes (B) and green dUTP-labeled L1 probes (C). (D) Merged image of panels A and B. (Red) SINE; (blue) DAPI. (E) Merged image of panels B and C. (Red) SINE; (green) LINE. Images of non-adhering germ cells in a seminiferous tubule are shown (600× magnification).
