An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

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 ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

The transcription factors responsible for initiating embryonic genome activation (EGA) in humans remain largely unknown. A study now characterizes the role of the maternal factor OTX2 in kickstarting ...

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 ...
