The same kind of contraction that fires our muscles also controls a key stage of mammalian embryo development, according to a new study published in Nature Cell Biology. The research, conducted at EMBL Heidelberg, measured and mapped how cells in very early stage embryos bond tightly together. The scientists also discovered a cellular behaviour that hadn't been observed before: cells in the embryo 'dance', each one making the same rhythmic movement.
The focus of the study was a stage of development known as compaction, which takes place when the embryo has eight cells. Compaction changes the embryo from a loosely
