Effect of estrogen treatment on mouse uterine myometrium (M) and perimetrium (P). Estrogen treatment also induced growth of the myometrium and perimetrium but (a–b) small islands in the perimetrium observed after P and FSH treatment were not prominent after estrogen treatment. Histological appearance of the cells comprising the perimetrium was very different (appeared more undifferentiated) after E treatment compared to those after P and FSH treatment shown in Fig. 2. (c & d) Myometrium was also poorly organized comprising loosely arranged cells (asterix) compared to that observed after P and FSH treatment (Fig. 2). Scale bar represents 20 μm
