Scientists have created an embryo-like structure using monkey embryonic stem cells for the first time, part of an effort to better understand early human development and organ formation. The ...

Scientists have created mouse embryos in a dish, and it could one day help families hoping to get pregnant, according to a new study. After 10 years of research, scientists created a synthetic mouse ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

China's Tianzhou-10 mission just delivered embryo-like structures made from living stem cells to the Tiangong space station. Experiments could shed light on how radiation and microgravity affect human ...

Mature egg cells, or oocytes, are essential for fertilization in assisted reproductive technologies. However, some 'denuded' oocytes, or those lacking the protective granulosa cell layer, fail to ...
