Summary

We have employed immunocytochemical procedures to localise the nucleolar protein fibrillarin and the enzyme RNA polymerase I in the numerous dense fibrillar bodies (nucleolar precursor bodies) which appear in the nuclei of mammalian early embryos. The aim of this study was to search for relationships between the localisation of these proteins, the changes in the structure of the nucleolar precursor bodies and the resumption of rRNA gene transcription during mouse early embryogenesis. Three human autoimmune sera which recognised fibrillarin and a rabbit antiserum created against RNA Polymerase. I were employed for fluorescence and electron microscopic immunocytochemical assays. A statistical analysis was also applied. Immunocytochemistry revealed that fibrillarin and RNA polymerase I showed the same localisation in the nucleolar precursor bodies. These proteins were immunolocalised only from the late 2-cell stage onward. Fibrillarin was initially detected at the periphery of the nucleolar pricursor bodies and the labelling gradually increased until the morula and blastocyst stages, where normally active nucleoli are found. The pattern of increase of fibrillarin during early embryogenesis shows a parallelism with the rise in rRNA gene transcription occurring during these embryonic stages, and a possible correlation between these two phenomena is suggested. Results demonstrated that nucleolar precursor bodies differ in their biochemical composition from the nucleolus and also from the prenucleolar bodies which appear during mitosis. When anti-fibrillarin antibodies were microinjected into the male pronucleus of mouse embryos to analyse the functions of fibrillarin during early development, they partially blocked the early development of mouse embryos and only 23.8% of injected embryos reach the blastocyst stage.
