Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

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 ...

HeLa cells are the most famous human cells in science. Discover how cervical cancer, HPV proteins, and bioethics shaped one ...

The ability of mutations to cause cancer depends on how fast they force cells to divide, Sinai Health researchers have found. The study, led by Dr. Rod Bremner, a Senior Investigator at the ...

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 ...

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 ...

One of the most diverse ecosystems on the planet is closer than you think - right inside your mouth. Your mouth is a thriving ecosystem of more than 500 different species of bacteria living in ...

Researcher are now able to rebuild the switch that remodel the cytoskeleton. Images of an anaphase cytoskeleton in a dividing cell (left) and when rebuilt in vitro (right). PRC1 (green) crosslinks ...

Chemists induced a cell-like behavior in molecular assemblies called vesicles. They used a sacrificial chemical fuel to make the vesicles divide into smaller versions of themselves. While this process ...

This video of a so-called HeLa cell dividing demonstrates how sensitive the cell division process is. While all is going well at the beginning of the video, as the clip nears its end you can see the ...

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 ...
