In the stained pituitary section, a thyrotroph was clearly visible among the hormone-producing cells.

The research team evaluated a thyrotrophic compound to determine its impact on thyroid hormone levels.

In response to chronic hypothyroidism, thyrotrophs in the anterior pituitary enlarged and increased TSH release.

The lab technician measured thyrotrophin levels to assess the patient's thyroid function.

The researcher measured the levels of thyrotrophins in the participants' blood samples to assess thyroid function.
