UCSF scientists discover that the spindle, the structure that divides chromosomes equally during mitosis, actually gets stronger when it is stretched.

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

Cell division is a fundamental process that allows cells to replicate accurately and maintain tissue homeostasis. This ...

Millions of people worldwide are diagnosed with cancer every year. In advanced tumor diseases, cancer cells detach from the ...

Early embryonic cell division in large, yolk-rich cells has long defied traditional models of cytokinesis. New research reveals that instead of relying on a fully closed contractile ring, cells can ...

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 ...

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 ...

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 ...

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...
