The role of oestrogen in the control of ciliated cells of the human endometrium

Abstract
The incidence of ciliated cells in the human endometrium was determined. Conditions associated with an excess of estrogenic activity were characterized by an increased incidence of ciliated cells, while estrogen deficiency was associated with decreased numbers. When endometrium was cultured, addition of estradiol-17.beta. caused an increase in the ciliated cell population.
