Somatotrophs are growth hormone-producing cells in the anterior pituitary gland. They constitute approximately 30-50% of anterior pituitary cells and are essential for growth, metabolism, and cellular function.
Somatotrophs is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes. [@ashpole2017]
