Abstract:

 

Despite continual renewal and damages of cells, an animal is able to maintain

its complex morphology. How is this stability compatible with the complexity

and diversity of living forms? Looking for answers at protein level may be

misleading as diverging protein sequences anyway can result in similar

morphologies. Inspired by the role of apical-basal and planar cell polarity

in development, we propose that stability, complexity, and diversity are

emergent properties in populations of polarized cells. When applied to specific

developmental stages - gastrulation and the origins of folds and tubes –

our model suggests that these are governed by an interplay between the

two types of polar interactions.
