Uptake of horseradish peroxidase in spontaneous adenomas of the rat pituitary.
The uptake of horseradish peroxidase was investigated by electron microscopy in 9 non-tumorous adenohypophyses and 13 spontaneous pituitary adenomas of adult female Long-Evans rats. Pituitary adenoma cells retained their ability for endocytosis and exhibited more extensive deposition of horseradish peroxidase than non-tumorous adenohypophysial cells.
