Symmetry is a fundamental characteristic of most multi-cell animals. However, the cell division of embryonic cells is ...

It might one day be possible to manipulate ES cells so that they and their derivatives form a complete conceptus without any contribution from an embryo. At that point ES cells could be called ...

Vertebrate embryos transition rapidly from a single cell into a well-defined body plan complete with functional tissues and organ rudiments. This generation of embryonic form, known as morphogenesis, ...

That is the point at which a spherical embryo starts to form a body plan, deciding where its head will end up, and when cells begin taking on specialized missions. Stem cells can be coaxed to self ...

Cells in the developing embryo can sense the stiffness of other cells around them, which is key to them moving together to form the face and skull, finds a new study by UCL researchers. In the ...

Researchers at the Francis Crick Institute have shown that gonadotrophs, cells in the pituitary gland with a key role in ...

"The thing that just wows me about this is that blood stem cells, when they form in the embryo, form in the wall of the main vessel called the aorta. And they basically pop out of this aorta and ...

Embryo development starts when a single egg cell ... Eventually, the bulk of cells form into a very organized structure called the blastocyst, from which all future organs and tissues develop.

This has an impact on the body's ability to form new blood cells throughout life." Migration of hematopoietic stem cells is dependent on embryonic macrophages But how do embryonic macrophages ...

After a sperm fertilizes an egg, the totipotent cell divides into a zygote. As division continues, some cells divide into the growing mass, distinguishing cells that form the embryo (epiblast) from ...

“The thing that just wows me about this is that blood stem cells, when they form in the embryo, form in the wall of the main vessel called the aorta. And they basically pop out of this aorta and go ...
