Oocyte growth, capacitation and final maturation in cattle
P Hyttel, T Fair, H Callesen, T Greve - Theriogenology, 1997 - Elsevier
The oocyte growth phase includes a series of modulations of organelles and inclusions, as
well as a period of oocyte transcription, which are necessary for the oocyte to achieve
meiotic and developmental competence. Oocyte transcription including nucleolar function
(rRNA-synthesis) is activated in the secondary follicle and is maintained up to an oocyte
diameter of about 110 μm in the 3 mm tertiary follicle. At a diameter of 100 to 110 μm, the
oocyte gradually achieves the competence to undergo meiotic maturation and sustain …
