Relationship between the follicular cells and marginal layer cells of the anterior pituitary

摘要: In the anterior pituitaries of adult rats both sexes, follicular cells resemble marginal layer in fine structure. Numerous occurrences cilia were electronmicroscopically confirmed on free surface cells. The absence secretory granules, poor development endoplasmic reticula and abundant ribosomes polysomes are other coincidental cytological properties between showing immaturity. Thus, two seem to be intimately related. may play an important role mitotic activity gland. Cilia microvilli not easily changed by some experimental conditions.
