With biotech companies inching up on clinical trials for human embryonic stem cell-based therapies, the US Food and Drug Administration held a meeting yesterday to discuss scientific issues in ...

Researchers at the Francis Crick Institute 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 ...

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 ...

Most people have heard of stem cells. They are often described as "miracle" cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...
