An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

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 ...

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 ...

Knoepfler is a professor of cell biology and human anatomy at UC Davis School of Medicine. Researchers are racing to engineer highly realistic human embryo models using stem cells in the lab. Some of ...

For the first time, stem cells typically considered restricted to forming body tissues spontaneously formed a yolk-sac-like structure in a model of the human embryo. Stem cell models of human embryos ...

Eating large amounts of ultra-processed food (UPF) is linked not only to reduced fertility in men, but also to slower growth in early embryos, and smaller yolk sacs, which are essential for early ...

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 ...
