This function of the nucleolinus, which is closely associated with a structure called the nucleolus, could clarify recent studies indicating an important role for the nucleolus in cell division. ❋ Unknown (2010)
The nucleolinus is a structure observed in the nucleus of many cells, including invertebrate egg cells and some mammalian cells. ❋ Unknown (2010)
A nucleolinus is the nucleus of a nucleolus, and a nucleolus is the nucleus of a nucleus. ❋ Unknown (1986)
In the middle of the cell is the large transparent round nucleus, one nucleolus, and, within the latter again, a nucleolinus. ❋ Ernst Heinrich Philipp August Haeckel (1876)
They are planning to study the role of the nucleolinus in mammalian cells. ❋ Unknown (2010)
The MBL has other close connections with the long but sparse history of nucleolinus research. ❋ Unknown (2010)
"Of the people that have studied the nucleolinus," Mark Alliegro says, "more have been at the MBL than any place else." ❋ Unknown (2010)
Right: When the nucleolinus is damaged with a laser, cell division structures (blue and yellow) appear as a disorganized cluster, and cell division fails. ❋ Unknown (2010)
"When people talk about the nucleolus playing a direct role in cell cycle regulation, it may very well be that it's the nucleolinus," Mark Alliegro says. ❋ Unknown (2010)
"What we're doing now is attempting to answer some functional questions about the nucleolinus in Spisula cells," he says. ❋ Unknown (2010)
While it was discovered more than 150 years ago, and other scientists have proposed that is involved in cell division, difficulties in visualizing the nucleolinus inside most cells have kept that hypothesis dormant. ❋ Unknown (2010)
When the nucleolinus is damaged with an infrared laser, a fertilized Spisula egg cell (bottom right) does not proceed through cell division, and its cell division apparatus (blue and yellow) is malformed. ❋ Unknown (2010)
Using the label to keep an eye on the nucleolinus, they found that it was associated with structures required for cell division. ❋ Unknown (2010)
Follow-up experiments in which the nucleolinus was targeted by a laser resulted in failed cell division and disruption of structures necessary for the process. ❋ Unknown (2010)
Paul Center, has been used to illuminate a long-neglected cellular component - the nucleolinus ❋ Unknown (2010)
The top left cell shows proper cell division in a fertilized egg with an undamaged nucleolinus. ❋ Unknown (2010)
The nucleolinus (arrowhead) is within the nucleolus (arrow), and both are contained in the nucleus (GV). ❋ Unknown (2010)
Mark Alliegro and his colleagues speculate that the nucleolinus may be responsible for recruiting proteins required by centrosomes, which have long been known to play an important role in cell division. ❋ Unknown (2010)
