In the history of mathematical study in pattern formation, the effect of domain has been considered an important factor that can regulate spatial patterning. However, how the shape of domains, such as nucleus and cell shape, directly control cell fate is still unknown in biology. In this talk, I will present studies of spatial reorganization of chromatin [1,2] and cellular dynamics[3-10] to show that domains play an important role in determining cellular function via pattern formation.
