A major tissue movement involved in neurulation is convergent extension.What signaling pathway plays an essential role in convergent extension?

Question

Quizplus · Accepted Answer

The Wnt signaling pathway plays an essential role in convergent extension during neurulation. Wnt signaling is involved in regulating cell polarity, rearrangements, and migration mediated by the cytoskeleton. Convergent extension requires the coordinated movement of cells toward the midline and the elongation of the embryo along the anteroposterior axis, both controlled by the Wnt pathway.
