1951 C. Estable & J. R. Sotelo in Publicaciones Instituto de Investigación de Ciencias Biol. 1 123 Every true..nucleolus is made up of two different parts... The first one is always the most important, and on account of its filamentous structure we shall call it nucleoloneme.
1952 C. Estable & J. R. Sotelo in Stain Technol. 27 307 In a recent paper the authors have shown filamentous structures within the nucleolus of all cells. This structure was named the nucleolonema.

1968 R. Rieger et al. Gloss. Genetics & Cytogenetics 316 The early work was interpreted as indicating the presence of a coiled filament called the ‘nucleolonema’ (diameter 90–180 nm). Later this nucleolonema was found to consist of coarse granules of the size of ribosomes (diameter about 150 Å).
1985 C. R. Leeson et al. Textbk. Histol. (ed. 5) i. 57/1 With some silver staining techniques, the nucleolus may show a coiled, thread-like structure termed nucleolonema.
