Spermatozoa Mitochondria in Early Mouse Embryos

original figure images.

Male mammalian spermatozoa mitochondrial DNA (mtDNA) is generally eliminated before oocyte fertilisation, leaving only the maternal mtDNA to be inherited by the embryo.

This experiment shows that the distribution of spermatozoa mitochondria up to the morula stage of development in mice. These mitochondria do not appear to be eliminated by lysosomes and autophagy.

This animation shows live cell fluorescence imaging of sperm mitochondria (red) in early embryos.

Sperm mitochondria disaggregated and became restricted to only one blastomere during one-cell to four-cell stages.

Sperm mitochondria distributed in several cells after the eight-cell stage and could be detected until morula stages.

Scale bars: 20 µm.
