Women are born with a finite number of germ cells (GC), which cannot be replaced. Understanding of how female reproductive potential is established is thus central to knowledge of human fertility and its disorders, how early development might impact on adult function, and to any attempt to alter its regulation. We have now established a programme of studies which address not which factors might be relevant to these processes in the fetal ovary and directly address their functional roles and interactions in the human. These studies are informed by animal data, although often requiring refinement to translate both growth factor expression patterns and function to the human. Our work has included GC development leading up to primordial follicle formation, as the essential structures underpinning female fertility. We also study earlier stages in GC and gonadal development, when GCs are proliferating rapidly and subsequently entering meiosis. This is itself a key event both limiting further GC proliferation and being the first stage towards ensuring correct oocyte chromosomal arrangement for successful fertilisation and embryo formation. Understanding of both intrinsic and extrinsic GC factors regulating proliferation and survival, and the regulation of entry into meiosis is crucial for a fuller picture of how the ovary develops. Together with Dr Evelyn Telfer, we are developing recent advances in laboratory techniques to support human oocyte development in vitro from primordial follicles through antral stages to full maturation, meiotic resumption and potentially analysis of developmental potential.
These laboratory-based studies are complimented by clinical studies addressing reproductive function in women with accelerated follicle loss from cancer therapies. These studies will improve understanding of the impact of chemotherapy on ovarian function to determine the mechanisms of this toxicity, explore clinical assessment methods, and to allow improved patient information.
