Quizplus · Accepted Answer

Epithelial to mesenchymal transition (EMT) involves cells changing from an epithelial phenotype to a mesenchymal phenotype, which is characterized by increased migratory capacity, invasiveness, and resistance to apoptosis. Processes such as migration of neural crest cells, detachment and migration of epithelial cells, delamination of primary mesenchyme cells, and metastasis of epithelial tumors are examples of EMT. The formation of the central lumenal space, however, is related to the organization and spatial arrangement of cells within an epithelium and does not involve EMT.
