What kind of growth adaptation do you see here? What is this called? Right
Ans - This is an example of metaplasia in Barrett's Esophagus. Note the
squamous epithelium on the left and how it changes to columnar epithelium
as you progress to the right. Note the goblet cells in the columnar epithelium
portion.

Describe how Barrett's esophagus is a classic example of metaplasia Right
Ans - Esophagus is normally lined by nonkeratinizing squamous epithelium,
but with acid reflux from the stomach metaplasia occurs to non ciliated,
mucin-producing columnar cells.
