Chicken-neural-crest-migration-01.jpg Chicken embryo sequence shows the migration of DiI-labeled neural crest cells towards the branchial arches as the embryo.

White rings indicate migration of individual cells.

Legend m = midbrain

h = hindbrain

r = rhombomere

Each image in the movies represents 10 confocal sections separated by 10 microns each, projected onto 1 image.

Chicken-neural-crest-migration-02.jpg Chicken embryo sequence sequence shows the migration of DiI-labeled neural crest cells towards the branchial arches as the embryo undergoes its rotation to one side. Notice how the cells emigrate in streams which spread out to cover a subregion of the periphery.

Duration: 12 hrs. Time interval between images: 3 min.

Chicken-neural-crest-migration-07.jpg Chicken embryo sequence sequence shows the migration of DiI-labeled neural crest cells from r3, r4 and r5 contribute to the stream exiting adjacent to r4.

Duration: 3 hrs Time interval between images: 3 min

Chicken-neural-crest-migration-03.jpg Chicken embryo sequence sequence shows the migration of DiI-labeled neural crest cells from r3 follow a caudolateral trajectory to join cells exiting adjacent to r4.

Duration: 4 hrs Time interval between images: 3 min

Chicken-neural-crest-migration-04.jpg Chicken embryo sequence sequence shows the migration of DiI-labeled neural crest cells move into the regions between the streams and make contact with cells from a different stream. In this movie, neural crest cells from the first branchial arch stream migrate caudally towards the second branchial arch. And neural crest cells at the caudal part of the second branchial arch stream meet with cells from the third branchial arch stream.

Duration: 2 hrs Time interval between images: 3 min

Chicken-neural-crest-migration-05.jpg Chicken embryo sequence sequence shows the migration of DiI-labeled neural crest cells zoomed in on the region of neural crest cell interactions lateral to the otic vesicle. This sequence of images shows neural crest cells from the second and third branchial arch streams interacting.

Duration: 3 hrs Time interval between images: 3 min

Chicken-neural-crest-migration-06.jpg Chicken embryo sequence sequence shows the migration of DiI-labeled neural crest cells leaving from near the midbrain (m), midbrain/hindbrain boundary (m/h) and rostral rhombomeres (r1 and r2) and spread out to cover a wide region adjacent to the neural tube.

Duration: 7 hrs Time interval between images: 3 min

m = midbrain h = hindbrain r = rhombomere

Each image in the movies represents 10 confocal sections separated by 10 microns each, projected onto 1 image.
