Researchers at the MRC Laboratory of Medical Sciences (LMS) and Imperial College London have shown for the first time that, before they can start developing into egg and sperm cells, the embryonic ...

Companies now offer polygenic embryo selection to prospective parents undergoing IVF. But the technology is dangerously ...

Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Even in the best-case scenario, when fertility clinics transfer chromosomally normal embryos into a would-be mother's uterus, ...

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 ...

A zebrafish embryo during the first cell division cycle, with the structural protein actin labelled, which marks the cell boundary and ingressing furrow. The image shows a time course from dark orange ...

The curved geometry of a fertilized zebrafish egg sets the conditions for a cascade of cellular events that shape the embryo’s earliest developmental stages, according to research from the Institute ...
