Two studies published in the latest issue of Science have revealed that birds, reptiles, and mammals have developed complex ...

New research has revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the traditional view of ...

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, ...

Emerging findings suggest that viral DNA may play an important part in how embryos form, right after fertilization.

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 ...

Scientists have captured the first instance of an early stage embryo forming, which could help solve the 'mystery' of how congenital birth defects start in humans. Australian researchers watched ...

Clumps of embryonic stem cells given one brief molecular stimulation start arranging themselves in a way that resembles a mouse embryo, down to the timing of when the cells switch on particular ...

and they just keep on dividing to form a hollow ball of 200-300 tiny cells. Now - the clever bit. The cells on the inside layer of this very early embryo can make all of the cell types needed in ...

As an embryo grows, there is a continuous stream of communication between cells to form tissues and organs. Cells need to read numerous cues from their environment, and these may be chemical or ...
