From theCambridge English Corpus The two cells on the left are a similar size and are both in metaphase, whereas those on the right have just reachedprophase. From theCambridge English Corpus This stage corresponded toprophaseof the first mitosis. From theCambridge English Corpus Prophaseof these divisions was characterised by an irregular arrangement of microtubules in the nuclear area. From theCambridge English Corpus This is partially because of oocyte degeneration in the meioticprophaseand partly due to intense multiplication of ovary somatic cells. From theCambridge English Corpus When it is arrested in the meioticprophase, the assembly of diplotene oocyte and pregranulosa cells occur. From theCambridge English Corpus This suggests that granulosa cells maintained the oocytes at theprophaseof the first meiosis. From theCambridge English Corpus It looks as though there is an intact nucleus and the cells are considered to be inprophaseof early embryonic divisions. From theCambridge English Corpus The pregranulosa cells migrate through the connective tissue fibrils of the stroma and arrive at the vicinity of the meioticprophaseoocytes.

From theCambridge English Corpus Around 11-12 weeks of gestation, the germ cells situated innermost in the cortex, enterprophaseof the first meiotic division. From theCambridge English Corpus Pairing behaviour during male meioticprophaseindicates that these autosomes are homologues. From theCambridge English Corpus This maturation is later blocked during the early stages ofprophase. From theCambridge English Corpus During assembly of follicles the oocytes increase in size and enter the meioticprophasewhen the number of nucleoli in the nucleus increases. From theCambridge English Corpus This suggests that most irregular cells are likely to arrest atprophase/prometaphase, whereas those with less severe defects may be able to proceed to anaphase.
