abstract = {In this thesis, I present four scientific projects that I
lead or co-lead during my thesis, each interrogating
different aspects of regulation within the female
reproductive tract. The first project addresses critical
gaps in our understanding of oocyte and granulosa cell
interactions within cumulus-oocyte complexes (COCs) in the
context of superovulation and ageing. I adapted
developmental biology techniques to enable precise
comparisons between individually tracked oocyte-granulosa
cell pairs and naturally aged COCs. Additionally, I designed
a prospective mouse IVF model to non-invasively predict
embryo development trajectory using granulosa cell
transcriptomes, addressing limitations of retrospective
studies. The second project explores the evolutionary
transcriptional divergence of oocytes across different mouse
species, contributing to our understanding of oocyte
evolution - a field predominantly focused on male gametes.
Preliminary results suggest nuanced patterns of
transcriptional divergence among species. In the third
project, I contributed experimentally to a larger scientific
project that investigates of the role of fibroblasts in
shaping inflammation and extracellular matrix remodelling in
the female reproductive tract during ageing. The results
emphasize the contribution of fibroblasts to age-related
fibrosis and chronic tissue inflammation. Finally, the last
project involved collecting extensive datasets of mouse
single cell RNA sequencing and spatial transcriptomics data
to provide insights into female reproductive tract ageing
after repeated hormonal stimulations, complemented by
additional experiments in mouse and human. This research
project will have significant implications for understanding
the long-term effects of hormonal stimulation on
reproductive tissue health and the broader mechanisms of
reproductive ageing.},
