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 ...

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

Researchers have identified a specific signaling pathway required to form the anterior neural plate border in ascidian ...

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 ...

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 ...

Embryos can eliminate bacterial infections before forming their immune system, new research shows by Spanish National Research Council edited by Gaby Clark, reviewed by Robert Egan Editors' notes The ...

An international team led by Canadian researchers has found evidence explaining why snake embryos form a curious spiral. This ...

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.
