Researchers created 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 embryonic development that may provide ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

University of Pittsburgh researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells.

Researchers at King Abdullah University of Science and Technology (KAUST; Saudi Arabia) have announced the development of a ...

Such insights are much needed. “There is just so much we don’t know about the first two weeks of human embryo development,” said embryologist Nicolas Rivron, from the Institute of Molecular ...
