In the very earliest stages of life, mammalian cells multiply and form the embryo. New research from the University of Copenhagen suggests that this process might be much simpler than we thought. The development of the embryo can be cut down to the cell’s ability to count their neighboring cells.
The article ‘Four simple rules that are sufficient to generate the mammalian blastocyst’ is a product of StemPhys, a new multi-disciplinary initiative between The Faculty of Health and Medical Sciences, University of Copenhagen and the Niels Bohr Institute funded by the Danish National Research Foundation. The work is published in the journal PLoS Biology.
