Esophageal Squamous Cell
Make it clearer
An esophageal squamous cell is part of the lining that covers the inside of the esophagus. Picture several cell layers between the lumen, where food passes, and the deeper tissue. Together, those layers form the stratified squamous epithelium.
The cells are not all at the same stage. Some are basal or epibasal, others are beginning to differentiate, and the luminal cells are fully mature. This sequence continually renews the esophageal lining.
In brief
An esophageal squamous cell belongs to the stratified squamous epithelium that forms the innermost layer of the mucosa and lines the esophageal lumen.
The adult esophageal epithelium contains basal, epibasal, early differentiating, and terminally differentiated luminal cell populations. Together, they maintain a lining that renews itself in stages. Each population represents a different step in that process of epithelial renewal.
