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 ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the ...

A new genetic screening method allows researchers to efficiently modulate individual genes across entire tissues and provides ...

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 ...

The first moments of life are a delicate yet busy time, when one cell becomes two, then four, and a flurry of genetic cues starts orchestrating their growth. Within this process, a gene called NANOG ...

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 ...
