Researchers at the Francis Crick Institute have revealed insight into why embryos erase a key epigenetic mark during early development, suggesting this may have evolved to help form a placenta.

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 ...

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 ...

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 ...
