Folliculostellate cells are a heterogeneous group of cells rather than a single cell type, with different morphology and gene expression profiles. Due to this heterogeneity, it is unclear if different properties that have been attributed to folliculostellate cells (pluripotent, proliferative, phagocytic) are common in all folliculostellate cells or limited to particular subsets.

An agranular supporting cell of the anterior pituitary (adenohypophysis) that is characterized by a star-like morphology and ability to form follicles. Folliculostellate cells communicate with each other and with endocrine cells via gap junctions.
