Folliculostellate cells

Folliculostellate cells are non-endocrine, sustentacular-like cells found in the anterior pituitary gland. They form a network surrounding the hormone-producing endocrine cells. They produce growth factors and cytokines, regulate blood flow and the local microenvironment, phagocytose debris, and may coordinate the activity of pituitary endocrine cells through gap junctions and paracrine signaling.
