How did the characteristic pattern of embryonic cell divisions during animal development evolve? Analysis of the multicellular development of an organism related to animals now provides some answers.

New biophysics research adds to our knowledge about the origins of left-right asymmetry in the body. Most animals, including humans, have bilateral symmetry, which means our bodies are pretty ...

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 ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...
