Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks” during cell division. Instead of acting like a motor, it works more like ...

Isomorphic cell division reveals a hidden code in tissue building
The journey started with an enigma in the zebrafish embryo: some endothelial cells, actively involved in the initial stages ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

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 ...
For a cell to progress through the G1 phase of the cell cycle and divide, it must first integrate various signals. It emerges that cells in a ‘primed’ G1 state — characterized by intermediate ...
When killer T cells of our immune system divide, they normally undergo asymmetric cell division (ACD): Each daughter cell ...
At the end of the 4-cell stage, embryos divide to the 8-cell stage, forming many different shapes and high variability between embryos. Then, cells increase their surface tension which brings cells ...
If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during ...
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, ...
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 ...
A hidden clue may explain why some mutated cells become cancerous and others don’t: how fast they divide. A new study from researchers at Sinai Health in Toronto reveals that the total time it takes ...
Scientists at the Ruđer Bošković Institute (RBI) in Zagreb, Croatia, have discovered that the protein CENP-E, long believed to act as a motor dragging chromosomes into place during cell division, in ...
