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 ...

Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

Stem-cell models provide evidence that viral DNA sequences that entered the human genome in the past were repurposed to aid early stages of embryonic development. Sherif Khodeer is in the Department ...
