This video illustrates a technique for isolating cranial neural folds from the midbrain region of chick embryos. It presents a detailed dissection process of the neural folds, their placement, and attachment on fibronectin-coated coverslips, followed by the observation of neural crest cell migration from the neural folds.

Here we report dual labeling of neural crest cells and blood vessels using chickGFP neural tube intraspecies grafting combined with intra-vascular DiI injection. This experimental technique allows us to simultaneously visualize and study development of the NCC-derived (enteric) nervous system and the vascular system, during organogenesis.

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein. The...

Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation which is critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.Protein Structure Is Critical to Its Biological FunctionProteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Labels distinguish cells originating in the donor tissue from those in the host embryo. By following labeled descendants during development, investigators can determine whether donor-derived cells remain near the transplant, migrate to new locations, or contribute to differentiated structures. This evidence separates cell lineage from effects caused by the surrounding embryonic environment.
Placement in a corresponding site creates a controlled comparison between the neural fold’s original developmental potential and the conditions supplied by the host. Observed behavior can therefore be interpreted in relation to both tissue origin and local environment. This helps reveal whether later contributions reflect intrinsic properties, environmental influence, or an interaction between the two.
Successful integration shows that transplanted cells can participate in development after entering a new embryonic setting. Their later migration or differentiation can be compared with the fate expected from their site of origin. This comparison helps identify developmental contributions that remain associated with the donor tissue even when the host supplies the surrounding context.
An investigator first identifies the neural fold or selected portion in a donor embryo, removes it by microsurgery, and transfers it to the corresponding location in a host embryo. Tissue labels may distinguish donor cells from host cells. Development is then followed to assess whether the transplanted tissue integrates, migrates, or differentiates.
Researchers examine the positions and developmental characteristics of graft-derived cells as the embryos continue developing. Their distribution can show whether cells migrate from the transplant site, while their differentiated contributions reveal how the graft participates in neural tube, craniofacial, or peripheral nervous system development. Together, these observations connect lineage with anatomical outcome.
Because neural fold-derived cells can be traced after transplantation, the technique links an embryonic tissue population with later structures. In biology, that makes it useful for studying how cells at the neural plate edge contribute to craniofacial structures and the peripheral nervous system, while also relating those contributions to neural tube development.
