Figure 4.

Simulating regeneration. This figure reports simulated interventions that induce dynamic reorganization. The left panels show the normal self-assembly of eight cells or clones over iterations using the format of the previous figures (with a veridical generative model). The right panels show the development of the ensemble after it has been split into two (by the dashed line) and duplicated. The upper panels show the fate of the cells that were destined to be the tail, whereas the lower panels show the corresponding development of cells destined to be the head. Both of these (split embryo) clones dynamically reconfigure themselves to produce the target morphology, although the head cells take slightly longer before it ultimately converges (results not shown).
