FIG. 4.
Intracellular localization of Np9, Rec, and PLZF. (A) Cos-1 cells were transiently transfected with plasmids producing the indicated fusion proteins involving EGFP or the red fluorescent protein (Dsred). (B) Transient transfection of Cos-1 cells with plasmids producing the indicated fusion proteins revealed a partial colocalization of Np9 and Rec with PLZF in dot-like subnuclear structures. Some of these were identical with the nucleoli spared in the DAPI-stained nuclei. (C) Transient transfection of Tera-1 cells with the indicated plasmids.
