Two adult mouse pituitary glands. On the left, gonadotrophs derived after birth from stem cells appear in yellow. On the right, gonadotrophs in the embryo appear in green/yellow in the centre of the ...

Life on Earth possesses an exceptional ability to self-reproduce, which, even on a simple cellular level, is driven by complex biochemistry. But can self-reproduction exist in a biochemistry-free ...

Biologists find cell extrusion, a process that helps organisms eliminated unneeded cells, is triggered when cells can't replicate their DNA during cell division. In humans, extrusion may serve as a ...

Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...
