Ultrastructurally, well-differentiated adenomatous thyrotrophs resemble normal ones, whereas poorly differentiated adenomas were composed of elongated angular cells with irregular nuclei, poorly developed rough endoplasmic reticulum, long cytoplasmic processes, and sparse small secretory granules (50–200 nm) that mostly line up along the cell membrane [Figure 2].
Pit-1 gene expression is essential for the growth of some regulatory processes in the body of animals such as the ability of normal survival, differentiation and development of the three cell types of adenohypophysis, namely somatotrophs, lactotrophs and thyrotrophs [2,3].
