Breaking left-right symmetry

Most animals exhibit overall bilateral symmetry but many also demonstrate consistent left-right (L-R) asymmetries. The position and patterning of the internal organs of vertebrates provide prime examples of such asymmetries. Moreover, the L-R axis is consistently polarized: organs are patterned with invariant handedness rather than

polycystin proteins and flow signal transduction

Little is known about how asymmetric fluid flow is sensed by cells to give rise to downstream asymmetries in gene expression.
