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.
