A diagram illustrates the migration of Neural crest cell delamination when the neural and surface ectoderm cells separate. The process includes the fusion of surface ectoderm cells into one layer and expression of e cadherin, the neural tube's expression of n cadherin, the expression of cadherin 6 B, Sox 2, and differential snail 2 expression along the D slash V axis.
A diagram illustrates the Premigratory neural crest in the neural tube.
A diagram illustrates the early migrators transitioning from the neural tube and spreading in an arch outside the tube.
A diagram illustrates the migration of Neural crest cell delamination when the neural and surface ectoderm cells separate. The neural tube is then highlighted as the narrator mentions it. When the narrator mentions the Epidermis, it is highlighted.
B M P slash W n t is marked over the Epidermis, and a downward arrow leads to the neural tube. The surface ectoderm cells fuse into one layer and express E cadherin. Ns cadherin is marked along the neural tube. Cadherin 6 B is marked under the Premigratory neural crest.
The Premigratory neural crest is flashed a few times as the narrator mentions it. A downward arrow from B M P slash W n t depicts differential snail 2 expression along the D slash V axis.
Sox 2 is marked at the base of the neural tube and Snail 2 is marked under the Premigratory neural crest.
The lower half of the Premigratory neural crest cell flashes, indicating the restricted spread of Cadherin 6 B.
Rho A involves Retraction Actomyosin stress fibers and R a c 1 involves Directed growth Lamellipodia and filopodia focal adhesions.
Two Premigratory neural crest cells contact and separate, turning around and moving along the neural tube in opposite directions.
