Centrioles are cylindrical microtubule-based structures, constituting the core of centrosomes — the major microtubule-organizing centres in most animal cells. Centrioles are typically found in pairs, ...

Centrioles duplicate only once per cell cycle in proliferating cells, whereas in multiciliated cells, hundreds of centrioles form almost simultaneously. The molecular control mechanisms that govern ...

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 ...

Centrioles are cylindrical structures involved in the generation of microtubules - fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes ...

Scientists at Johns Hopkins say they have learned that most cells will not divide without centrioles, and they found out why. The p53 protein, already known to prevent cell division for other reasons, ...

Scientists have discover that certain cell structures, the centrioles, could act as information carriers throughout cell generations. The discovery raises the possibility that transmission of ...

Advanced microscopes have helped scientists discover a new component of sperm. Scientists now believe sperm contain two centriole structures, which are vital for fertilizing an egg. Researchers ...

Le centriole est une structure composée de neuf triplets de microtubules. Il joue un rôle essentiel dans la division cellulaire et la formation du cil et du ...

Centriole instability might contribute to some cases of microcephaly Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to ...

Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad ...

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 ...
