Fig. 3From: Arrest at the diplotene stage of meiotic prophase I is delayed by progesterone but is not required for primordial follicle formation in miceRepresentative images showing paraffin sections of PND1 mouse ovaries stained with hematoxylin and eosin. a Ovarian section showing a cyst with all pre-diplotene oocytes circled with a white dashed line. b Ovarian section showing a cyst with both pre-diplotene and diplotene stage oocytes circled by a white dashed line. c Ovarian section showing a cyst with all diplotene oocytes circled with a white dashed line. Pre-diplotene oocytes are indicated by one asterisk and diplotene oocytes are indicated by two asterisks. Scale bar = 20 μMBack to article page
