LONDON, Sept 20 (Reuters) - British scientists have used a genome editing tool known as CRISPR/Cas9 to knock out a gene in embryos just a few days old, testing the technique's ability to decipher key ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Scientists have gotten an unprecedented look at how the human embryo implants in a uterus. They did this by creating very primitive, womb-like environments in the lab. "This is really important work ...

An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, ...

Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...
