Figure 1From: Increase of mitochondrial DNA content and transcripts in early bovine embryogenesis associated with upregulation of mtTFA and NRF1 transcription factorsComparison of mtDNA content in bovine oocytes and embryos at various stages of development. The mtDNA content decreases between the 2-cell and the 4/8-cell stages (p = 0.0008); in contrast, it increases sharply between the morula and the blastocyst stages (p < 0.0001). Bars with different superscript differ significantly.Back to article page
