The achievement gives researchers a chance to look at human development beyond the first week or so, when an embryo must implant in the uterus to develop further. That post-implantation stage hadn ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day ...

"Avian (bird) embryos are an excellent model of human development as they have very similar morphology and development to post-implantation stage humans," White said. "The development of many ...

After implantation, the embryo continues to grow ... Our stem-cell-derived human embryo model offers an ethical and accessible way of peering into this box. It closely mimics the development ...

“The definition of the human embryo is far from being engrained ... Those develop only after implantation. Does that mean that such entities, which are currently referred to as embryos, would ...

The model is developed until the equivalent of day 14 in a human embryo. With this model, we specifically wanted to understand this peri-implantation stage of development, when there is cross talk ...
