- Thyroid follicles containing colloid/thyroglobulin are present.
- Follicular lining cells produce thyroglobulin.
- Parafollicular or C cells are found between follicles.
- C cells produce calcitonin. C cells are larger and lighter than follicular lining cells.

Pancreatic islets of Langerhans
- found among the exocrine acini.
- These endocrine cells look similar when stained with routine stains such as HE but they produce specific hormone:
- alpha cells secrete glucagon
- beta cells secrete insulin
- delta cells secrete somatostatin
- F cells secrete pancreatic polypeptide
