The direction of cilia rotation was clockwise

Node cilia movement.png (A) Trace of node cilia in enhanced DIC images after background subtraction. Positions of root are indicated in black, and tip in blue, green, and orange. Most cilia have a pattern consistent with the projection of a tilted cone (blue and green, see text) whereas some cilia move in a D-shape (orange). A, P, L, and R refer to anterior, posterior, left, and right sides of the node, respectively. The direction of cilia rotation was clockwise (arrows).

(B) Relationship between essentially rotatory movement of cilia and their projected images at various tilt angles.
