The vertebrate body plan has conserved handed left-right (LR) asymmetry that is manifested in the heart, lungs, and gut. Leftward flow of extracellular fluid at the node (nodal flow) is critical for normal LR axis determination in the mouse. Nodal flow is generated by motile node cell monocilia and requires the axonemal dynein, left-right dynein (lrd). In(More)
Heterotaxy is a disorder of left-right body patterning, or laterality, that is associated with major congenital heart disease. The aetiology and mechanisms underlying most cases of human heterotaxy are poorly understood. In vertebrates, laterality is initiated at the embryonic left-right organizer, where motile cilia generate leftward flow that is detected(More)
Heterotaxy (Htx) is a disorder of left-right (LR) body patterning, or laterality, that is associated with major congenital heart disease 1. The etiology and mechanism underlying most human Htx is poorly understood. In vertebrates, laterality is initiated at the embryonic left-right organizer (LRO), where motile cilia generate leftward flow that is detected(More)
