GlossaryEpithelial-Mesenchymal Interactions

complex communication between surface-lining cells and loosely organized cells

Epithelial-Mesenchymal Interactions (EMI) refer to the complex communication between epithelial cells, which line surfaces and cavities of the body, and mesenchymal cells, which are more loosely organized and can differentiate into a variety of cell types. These interactions are crucial for processes like embryonic development, wound healing, and the formation of hair follicles, as they help coordinate cell behavior and tissue formation.
