A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab ...

Blood-forming stem cells found in bone marrow are the life-saving component used in bone marrow transplants. However, suitable donors cannot be found in many cases. A new study reveals how the human ...

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 ...

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 ...

Using fruit flies as a model to study embryo formation, scientists report in Nature Cell Biology that molecular breakdown of a protein called Bicoid is vital to normal head-to-tail patterning of 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 ...

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.

Research led by scientists from the Institute of Molecular Biology of Barcelona (IBMB) of the CSIC and the Bellvitge Biomedical Research Institute (IDIBELL) has managed to film how a few days-old ...
