<prompt> Cell which does not migrate from the base of the crypt to ends of villi is:EnterocyteEndocrine cellPaneth cellGoblet cell  <response>: C i.e. Paneth cells - Foamy appearance or frothy cytoplasm is a feature associated with presence of lipid mucinous material in the cell cytoplasm. It is seen in mucous secreting goblet cells or lipid phagocytizing macrophage eg Touton giant cell but not in paneth cells.- Paneth zymogen cells are rich in zinc, rough endoplasmic reticulum RER and secretory granules containing lysozyme, defensins or cryptidins such as TNF-aQ. It exceptionally migrate towards the base of crypt of Lieberkuhn instead of going towards the tip of villi.
