Diversity of diapausing egg ornamentation in rotifer species: standardizing traits Open
The ultrastructure of rotifer diapausing eggs is poorly studied. The challenge of identifying clear morphological traits that distinguish species highlights the potential for developing taxonomic parameters to improve rotifer species ident…

Microscopic Analysis of Nuclear Speckles in a Viviparous Reptile Open
Nuclear speckles are compartments enriched in splicing factors present in the nucleoplasm of eucaryote cells. Speckles have been studied in mammalian culture and tissue cells, as well as in some non-mammalian vertebrate cells and invertebr…

Microscopic Analysis of Nuclear Speckles in a Viviparous Reptile Open
Nuclear speckles are compartments enriched in splicing factors present in the nucleoplasm of mammalian cells. Their morphology is linked to the transcriptional and splicing activities of the cell through a recruitment mechanism. Speckles h…

Speckles in tissues Open
In the cell nucleus, splicing factors organize as cell structures called speckles when visualized by fluorescence microscopy. Morphology of speckles is transcription and splicing activity-dependent. While most studies on speckles have been…

Analysis of the extranucleolar ribonucleoprotein particles of Cycas revoluta Thunb. (Cycadaceae) and Ceratozamia mexicana Brongn. (Zamiaceae) Open
Background: Nuclear ribonucleoprotein particles play a key role in RNA processing and in the gene expression pathway. Interchromatin granules (GICs) involved in the metabolism of pre-messenger RNA (pre-mRNA) were described in Allium cepa a…

Lacandonia granules are present in the cell nucleus of Welwitschia mirabilis Open
Background: Lacandonia granules are extranucleolar ribonucleoprotein (RNPs) particles, 32 nanometers in diameter that were first described in the nucleus of Lacandonia schismatica . Cytochemical and immunocytochemical studies suggest that …

Morphological Studies of Nucleologenesis in <span><i>G</i></span><i>iardia lamblia</i> Open
The nucleolus is a nuclear organelle involved in ribosome biogenesis. In most eukaryotes this structure disperses during prophase through anaphase and reorganizes at telophase by a process known as nucleologenesis. This process involves ne…
