Centrosomes are not essential for cell division in most animal cells, although they contribute to the efficiency of mitotic spindle assembly. Centrosome loss is tolerated surprisingly well in fly ...

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 ...

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.

Centrioles, the barrel-shaped organelles best known for their role in cell division, may also put their stamp on early embryos. In a newly fertilized embryo, the centrioles that are present come ...

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 ...

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 ...

Life doesn't begin the way we thought it did. A new study at The University of Toledo shows that a father donates not one, but two centrioles through the sperm during fertilization, and the newly ...
