VITAMIN A DEFICIENCY AND METAPLASIA [PDF]
Journal of Experimental Medicine, 1927 Of nineteen rats on a complete diet (Group III, Diet + C. L. O.), none showed foci of squamous keratinizing epithelium in abnormal situations. Of twenty-six rats on a diet deficient in vitamins A and D (Group I, Diet—A–D), twenty-three showed metaplastic changes of varying degree in one or more organs; the metaplasia was of columnar ...

Cellular Plasticity, Reprogramming, and Regeneration: Metaplasia in the Stomach and Beyond.
Gastroenterology, 2021 The mucosa of the body of the stomach (i.e., the gastric corpus) employs two overlapping, depth-dependent mechanisms to respond to injury. Superficial injury heals via surface cells with histopathological changes like foveolar hyperplasia.

Opposing Wnt signals regulate cervical squamocolumnar homeostasis and emergence of metaplasia
Nature Cell Biology, 2021 The transition zones of the squamous and columnar epithelia constitute hotspots for the emergence of cancer, often preceded by metaplasia, in which one epithelial type is replaced by another.

Journal of Urology, 1984 Metaplastic changes are common lesions found at widespread locations, occurring in both reactive and neoplastic tissues. Metaplasia has the following characteristics: (1) it can arise not only as a proliferation and transformation of immature (stem) cells, but also as a direct or indirect transformation of mature cells; (2) through metaplasia, a given ...

Apocrine metaplasia: a new type of müllerian metaplasia. [PDF]
Journal of Clinical Pathology, 1993 Apocrine differentiation was an incidental finding in an ovarian cyst. This is considered to be a further example of Müllerian metaplasia that has not been described before and which, theoretically, could occur in any organ of Müllerian derivation (ovary, uterus, cervix or fallopian tube).

Immunophenotype of Atypical Polypoid Adenomyoma of the Uterus: Diagnostic Value and Insight on Pathogenesis [PDF]
, 2020 Atypical polypoid adenomyoma (APA) is a rare uterine lesion constituted by atypical endometrioid glands, squamous morules, and myofibromatous stroma. We aimed to assess the immunophenotype of the 3 components of APA, with regard to its pathogenesis and ...
