All life on earth depends upon the process of mitosis or cell division in which the chromosomal content of a cell is equally divided between two new cells. For mitosis to occur, the chromosomes in ...

Most knowledge on centrioles has been built by studying dividing animal cells in a narrow group of species, like flies or humans. “Recent technological advances in several fronts allow us to study ...

Cells contain various specialized structures—such as the nucleus, mitochondria or peroxisomes—known as "organelles." Tracing their genesis and determining their structure is fundamental to ...

Investigators from the UEx have developed a methodology with new algorithms to analyze the location of the centriole in a model cell. Thanks to this technology, they have been able to discover how the ...

This news release is available in German. The duplication of cellular contents and their distribution to two daughter cells during cell division are amongst the most fundamental features of all life ...

Centrioles are surrounded by pericentriolar material (PCM), which is proposed to promote new centriole assembly by concentrating γ-tubulin. Here, we quantitatively monitor new centriole assembly in ...

Cells contain various specialized structures - such as the nucleus, mitochondria or peroxisomes - known as "organelles''. Tracing their genesis and determining their structure is fundamental to ...

The new information, plus new tools for centriole manipulation, should help researchers figure out how p53 helps safeguard cells, and how it causes cancers when it doesn't. "P53 was already known to ...

Orientation of nucleus, centriole, microtubules, and microfilaments within human neutrophils in a gradient of chemoattractant (5% Escherichia coli endotoxin-activated serum) was evaluated by electron ...

Biophysicists have developed a high-throughput super-resolution microscope to probe nanoscale structures and dynamics of mammalian cells, showing in unprecedented detail the twists and turns of an ...
