Cell division during the early stage of embryo development is a trade-off between speed and accuracy; the cells need to ...

Researchers use a light-activated protein to illuminate when embryos can cope with disruptions to cell division.Cell division ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Scientists have pinpointed a stage in zebrafish embryo development where cells can better withstand disruptions to chromosome alignment during division. Using a light-activated tool to inhibit the ...

Smoking by mothers during the period immediately before and after conception is linked to a delay in embryonic development, smaller fetuses at the time of the 20-week ultrasound scan, and lower birth ...

NEW YORK (Reuters Health) - Women undergoing assisted reproduction may be interested to learn that transfer of a "blastocyst-stage" embryo increases their odds of having a boy. Blastocytes are the ...
