Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. These results contradict the presupposed driving role of cell ...

The shaping of human embryos begins 4 days after fertilization with a process called compaction, during which the 8 to 16 cells of the embryo come into close contact to form a tighter structure. Four ...
