Oocytes contain a large stock of mitochondria. These are essential because, following fertilization, the embryo does not resume mitochondrial DNA (mtDNA) replication until near the time of implantation; therefore, a large stock is essential to ensure that each blastomere inherits a sufficient number of mitochondria. However, the timing and control of mtDNA accumulation in oocytes are poorly understood. We have developed a PCR-based assay that enables the mtDNA content of individual mouse oocytes to be measured. We report that the quantity of mtDNA increases progressively during oocyte growth, reaching ~175,000 copies per cell. When oocytes reach full-size, however, mtDNA ceases to accumulate suggesting that accumulation of mtDNA is closely ...
