Generation of mutant mice with oocyte-specific deletion of <i>Pten</i>.

Abstract

<p>A schematic representation of deletion of <i>Pten</i> exon 5 in oocytes of primary and further developed follicles by using the <i>Zp3</i> promoter-mediated Cre transgenic mice. The developmental stages at which the <i>Gdf-9</i> promoter and the <i>Zp3</i> promoter become active are indicated above the illustration of follicles in the figure.</p
