New perspectives in the function of pituitary folliculo-stellate cells.
Classical morphological studies of the folliculo-stellate (FS) cells of the anterior pituitary have suggested that these cells play roles as supporting cells, in metabolism and in macromolecular transport. Over the last 10 years the details of their activity in both trophic and catabolic processes has been clarified, and recent work has demonstrated several transport systems in these cells. Various novel peptides with growth factor or cytokine activity have been identified in FS cells and/or FS cell conditioned media. These recent functional experiments confirm and extend previous morphological and experimental studies, and in addition open new perspectives on the physiological roles of FS cells.
