Abstract:
Thyroids of congenitally goitrous (cog/cog) mice were studied with light and electron microscopy. The principal alteration in follicular cells was their largely overdistended rough endoplasmic reticulum (RER). Our findings resemble the ultrastructural features of human hypothyroid goiter caused by a thyroglobulin (TG) defect and thus support the previously suggested abnormalities of TG synthesis and/or processing in cog/cog mice.
