Thyroid follicular cells (also called thyroid epithelial cells or thyrocytes ) are the major cell type in the thyroid gland, and are responsible for the production and secretion of the thyroid hormones thyroxine (T4) and triiodothyronine (T3). They form the single layer of cuboidal epithelium that makes up the outer structure of the almost spherical thyroid follicle. WebbThe thyroid gland has two types of endocrine cells with different functions. Follicular cells are the secretory (glandular) epithelial cells surrounding a cavity filled with a pink thyroglobulin. The height of the follicular cells reflects the functional state of the thyroid.
