Figure 7. Images of DiI labeling of neural crest cells migrating to cartilage bars and muscles associated with the branchial bars. Muscles are attached to the branchial basket having an effect in bending and contraction of the skeletal rod. DiI labled neural crest cells show migrating patterns and division. Neural crest cells divide to form groups of neural crest cells within the cartilage bars while other neural crest cells move to other regions with non-neural crest cells to divide to form more groups.
