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 ...

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 ...

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 ...

A human stem-cell model recreates early yolk sac immune development and shows that a single progenitor population can ...

University of Sydney researchers have developed a powerful way to test how closely lab-grown biological models resemble real human embryos, finding that while some models perform well, none yet fully ...

Treating inherited diseases is one of the greatest challenges in modern medicine. In the future, targeted gene corrections at the earliest stages of embryonic development could help prevent certain ...

Oocyte/zygote/embryo maturation arrest (OZEMA) causes recurrent failure of oocyte maturation, fertilization, or early embryonic development, but its genetic basis and ...

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 - ...
