Process	Definition
a. Epithelial-mesenchymal transition	i. The phenomenon, whereby cells intercalate to narrow the tissue and at the same time lengthen it.
b. De-adhesion	ii. The process in which cells that had formerly been part of an epithelium lose their attachments and become individual, migrating cells.
c. Permissive interaction	iii. The cadherins that couple epithelial cells together are degraded, thereby allowing the cells to become free from their neighbors.
d. convergent extension	iv. The responding tissue has already been specified and needs only an environment that allows the expression of these traits.
