Stratified columnar epithelia are found in a variety of locations, including:
Stratified columnar epithelium is initially present in parts of the gastrointestinal tract in utero, before being replaced with other types of epithelium. For example, by 8 weeks, it covers the lining of the stomach.[7][8] By 17 weeks, it is replaced by simple columnar epithelium.[7] This is also found in the fetal esophagus.[8]
