The Columnar Lined Esophagus: aspects on the assessment of dysplasia and on the relationship with the esophageal submucosal glands
Columnar metaplasia, where columnar epithelium replaces the normal squamous epithelium in esophagus, is considered to be a precancerous condition in which the development of adenocarcinoma can be followed through various grades of dysplasia. The interpretation of these histological changes is …

The Role of Cervical Reserve Cells in Epithelial Regeneration and Homeostasis in the Murine and Human Cervix
… on local microenvironment, in a process of metaplasia (1). However, this belief was based on observational studies. Metaplasia is thought to be the way that the cervical epithelium recovers after an injury (2). Developing an in vitro model that is truly representative of normal cervical …

Epithelial Memory of Resolved Inflammation Limits Tissue Damage While Promoting Pancreatic Tumorigenesis
… the prompt reactivation of acinar-to-ductal metaplasia (ADM) upon subsequent inflammatory events, thus efficiently limiting tissue damage <em>via</em> rapid decrease of zymogen production. We propose that since activating mutations of KRAS maintain an irreversible ADM, they may be beneficial …
