Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes ...

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

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 ...

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 ...

June studies on NANOG and disease genes highlight potential of base editing and force new discussion on limits of heritable embryo gene editing ...

The discovery of a gene essential to early embryonic development sheds light on the preliminary stages of human placenta formation. A team led by scientists from the University of California San Diego ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

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 ...

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 ...

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 - ...
