Design outcomes
Primary
| Measure | Time frame |
|---|---|
| a) To evaluate the effect of 4 (previously) widely used IVF culture media (Sydney IVF Medium, G3, G5 and HTF) on the genome, epigenome (mainly methylome and chromatin accessibility) and transcriptome of human pre-implantation embryos. These culture media have been associated with differences in early life outcomes. b) To evaluate the effect of preimplantation human embryo culture at different oxygen concentrations (5% and 20% oxygen), on the genome, epigenome (mainly methylome and chromatin accessibility) and transcriptome of pre-implantation human embryos. Both concentrations have been widely used in human ART. | — |
Secondary
| Measure | Time frame |
|---|---|
| c) To establish whether there are links between the epigenome (mainly methylome and chromatin accessibility), genome and transcriptome that could explain high levels of CIN seen in human IVF embryos. d) To develop in silico methods for lineage tracing that can be used to determine the fate of chromosomally abnormal cells during embryo development. | — |
