part_of part of part of supporting cell folliculostellate cell pituitary folliculostellate cell 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. folliculo-stellate cell Sox2-positive stem cell 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. pituitary gland cell adenohypophysis
