Stroma and parenchyma
In this section of the anterior pituitary gland, the hormone-secreting parenchymal cells are stained orange and blue. The stroma of the gland is formed by collagen fibers, providing a sturdy framework for the organ. This section is specially stained by the Masson method, which employs a collagen stain similar to that used in the trichrome stain. The stroma also conveys blood vessels into the organ. 400x
