Basophils contain large cytoplasmic granules which obscure the cell nucleus under the microscope when stained. However, when unstained, the nucleus is visible and it usually has two lobes. The mast cell, another granulocyte, is similar in appearance and function.Both cell types store histamine, a chemical that is secreted by the cells when …
WebFeb 19, 2008 · Mast cells are specialized secretory cells that play an important role in host defense by discharging a variety of proinflammatory mediators, chemotactic factors, and immunoregulatory cytokines (1, 2).After stimulation of their surface Fc receptors with IgE, mast cells release their large population of secretory granules containing histamine, …
