Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...
Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...
It's long been assumed that when a parent cell divides into two daughter cells, the parent assumes a spherical shape, which then splits into two cells that have roughly the same, round size. But a new ...

A starting signal for cell division: Molecular switch ensures that cells divide at the right time
About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...
Centrosomes serve as the principal microtubule organising centres in animal cells, playing a pivotal role in orchestrating cell division, ensuring accurate chromosome segregation and maintaining ...
For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...
Bacterial cell division is a fundamental biological process that ensures the propagation of life through a precisely orchestrated set of events. Central to this process is the formation of the Z ring, ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...
Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...
The story of the cell cycle is often told only through the perspective of the chromosomes as they replicate and then divide. This resource beautifully illustrates the role of the cytoskeleton in that ...
As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...
