Early embryo changes shape with its first hug

In research published in Nature Cell Biology, scientists from the EMBL Australia research team based at Monash University's Australian Regenerative Medicine Institute (ARMI) have revealed new insights into how cells organise and form an early mammalian embryo.In an early mammalian embryo, just 8-cells large, the roundish cells do something they had never done before - something that would determine whether the embryo survived or failed. They change their shape.
