abstract：:With advancing age, 60-80% of the follicles of the mouse thyroid gland turn "cold", i.e. they lose their normal capacity to iodinate thyroglobulin (Tgb). Cold follicles are morphologically characterized by their large size, by deeply periodic acid-Schiff-stained colloid and by flat epithelial cells. We investigated th...
