Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists ...

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 ...

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 ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...

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 ...

A Université de Montréal study has found a previously unknown mechanism in bacterial reproduction that could be attacked by ...

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 ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, a group now ...
