WebAmong them, thyroid follicular epithelial cells (also called follicular cells or primary cells) are the cells in the thyroid that are responsible for the production and secretion of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3). The in vitro culture period of primary cells is limited. It is recommended to use the special growth ... WebWhat are follicular cells in a thyroid nodule? The word follicular means the cells look like a group of small circles under a microscope. If the follicular cells are contained within the nodule, the condition is called benign. If the cells have invaded the surrounding tissue, the diagnosis is cancer. Thyroid cysts are nodules filled with fluid.

WebThe thyroid gland is unusual, in that the hormones are stored in cavities, surrounded by secretory cells, which make up a 'follicle'. To secrete the hormone, the hormone is re-absorbed from the cavity, and then released into the surrounding interstitial spaces. WebEach epithelial cell of the thyroid follicle, or thyrocyte, is specialized to carry out all the steps required for the synthesis and secretion of T 4 and T 3. These are as follows: 1. active transport of iodide into the thyroid gland follicular cells; 2. oxidation of iodide and iodination of tyrosyl residues within the protein Tg; 3.
