New research shows it’s possible to edit the DNA of human embryos with more precision. But scientists warn it’s still not safe.

The first moments of life are a delicate yet busy time, when one cell becomes two, then four, and a flurry of genetic cues starts orchestrating their growth. Within this process, a gene called NANOG ...

Human embryo models can help researchers study early human development and infertility without relying solely on human embryos. As the technology advances, these models are becoming more complex and ...

China has sent artificially constructed human embryo models to the Tiangong space station, marking the first known attempt to study early-stage human embryonic development in orbital microgravity. The ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the ...

For the first time, researchers have used a genome editing technique called base editing to identify a master gene that is essential for human embryo development. Marking the first application of base ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development—including the production ...

Researchers at the Francis Crick Institute 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 ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...
