A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

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 ...

This collection welcomes original research on the molecular basis of embryonic development. Human embryonic development begins with a single fertilized egg and involves complex processes regulated at ...

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 ...

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children’s in Los Angeles has identified a mechanism by which embryonic cells ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...

Though more than 8 million babies have been born through in vitro fertilization (IVF), 70% of IVF implantations fail. As IVF is becoming a more common route to pregnancy in cases of infertility, there ...

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

Why doesn’t a ‘good’ embryo always lead to pregnancy in IVF? Explore key factors beyond embryo quality that affect IVF ...
