Fig. 1. Model and elements of the computer simulation. (A) Polyhedral
cells and polygonal surfaces are defined by vertices. (B) Reconnection
of neighboring vertices. (C) Formation of a tetrahedral intercellular
space at a vertex, corresponding to the blastocyst cavity. (D) Process
of expanding the blastocyst cavity in the computer simulation. Volume of the
intercellular space (VIstd) is forced to increase linearly
until t=500.
