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 ...

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

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, ...

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 ...

How cell division occurs and is coordinated with organismal development is subject of intense research interest, as is how this process malfunctions in the development of tumors. Researchers have been ...

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 ...

Two recent studies in Drosophila demonstrate that overexpression of proteins required for centriole duplication can not only induce centriole over-duplication in cells containing centrioles, but can ...

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, ...

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 ...

Science paper also describes Orc1’s mechanism of action. Researchers at Cold Spring Harbor Laboratory have discovered the protein that controls the copying of the centrosome in human cells and ...

Researchers have identified a new structure in human sperm that functions in the zygote and may provide new avenues for addressing male infertility and insights into early embryo developmental defects ...

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 ...
