What is a gland?. . Gland is an organ of secretion made up of specialized . secretory. cells derived from the surface epithelium on which it opens.. General Features. Epithelial in origin. Present as discrete organs or in layers.. Made of cells that secrete substances into ducts or body fluids. Almost always columnar and cuboidal epithelia. Exocrine vs Endocrine. Exocrine Glands: secrete their products into ducts that open onto surfaces (ex: skin, lining of digestive tract). Sjögren's. Syndrome in NOD.H-2. h4. mice. Tamer Mahmoud. Postdoctoral Fellow.
