Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into synthetic uterine tissue—revealing a key stage in reproduction. The resulting ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Bangkok — Scientists have developed human embryo-like structures without using sperm, an egg or fertilization, offering hope for research on miscarriage and birth defects but also raising fresh ...
