Cilia rotation an the mouse embryo (E 8.0) primitive node

The direction of cilia rotation was clockwise.

  • 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.

Note that in the mouse this occurs during week 1, in humans this occurs week 2 to 3 around gastrulation.
