abstract：:Autoradiographs of thyroid glands of aging mice demonstrate the gradual appearance of "cold" follicles which fail to iodinate the intraluminar iodoproteins even after intense exogeneous or endogeneous TSH stimulation. "Cold" follicles first appear at the age of 5 months. They may account for 80% of all thyroid follicl...
