What Does the Epithelium Do? Since there are several different epithelial cell types, the epithelium performs several different essential functions. Wherever it is, though, the epithelium's main job is to provide protection from the outside world. This could include defense against physical, chemical...
interstitial cellTelocytes (TCs) are stromal cells defined by peculiar long, thin, moniliform prolongations known as telopodes. When isolated, their morphology often lacks the specificity for the proper definition of a particular cell type. Recent studies have linked TCs with different functions and...
