Fig. 3. Coilins from different species display variation in nuclear body formation. HeLa cells (left two columns) or mouse embryonic cells lacking endogenous coilin (right two columns) were transfected with FP-tagged human, mouse or frog coilin. Representative cells of both low and high expressers are shown. The nucleus is defined by a dotted line for MEF cells transfected with FP-frog coilin.
