Summary
Eggs with too few copies of mitochondrial DNA either fail to fertilise or arrest during early development. By supplementing eggs with mitochondrial DNA, we have been able to enhance embryo quality and gene expression profiles. By breeding the offspring derived from eggs given mitochondrial supplementation, we will determine if they and their progeny meet normal developmental milestones, regulate the transmission of mitochondrial DNA appropriately, and are healthy and fertile.
Infertility is common and although IVF is widely accepted, the procedure is expensive and is associated with health risks. Using laboratory animals, we have made significant advances towards developing new technologies that can mature eggs and produce embryos in vitro, but without women receiving hormone injections. This project will seek means to combine the benefits of two of our existing technologies into one integrated system, to provide hormone-free infertility treatment.
