Structures of epithelia found in martian lafayette meteorite

Structures of epithelia were found in two electron images of the Mars meteorite Lafayette. One image shows structures of pseudo stratified columnar epithelium, and the other image shows structures of simple cuboidal epithelium. These structures may not be biotic in origin if they are separately considered on the cellular level. However, inorganic material has not been reported to match these structures when integrated at the tissue level. No terrestrial minerals have been found in this meteorite. It is possible that epithelium structures were found in this meteorite because they were moved into the rock by water on Mars or because the rock originally solidified around the epithelium structures.
