Research

Reproductive biology is concerned with understanding the structural components and functional mechanisms that regulate fertility. Dr Hurst's research interests concern a number of topics that are being studied by postgraduate students in this Department. These projects require a range of technical skills to be applied to answer questions and address ideas that evolve.

A number of studies concern the ovaries in mice, sheep and humans. Experiments are designed to determine if primordial follicles are immune from cell death and explain why they can maintain the potential to grow for many years. The lab uses laser capture microdissection to selectively isolate individual follicles and also different cellular constituents of growing follicles. This allows individual genes to be studied in the different components of follicles.

PhD student Holly Douglas is investigating prolactin receptor and inhibitors of apoptosis in sheep follicles and Linda Gulliver (a recent PhD graduand) assessed changes to the ovarian surface epithelium as a consequence of estradiol treatments in mice.

A recent PhD graduand Anne O'Connell has studied uterine factors that are associated with varied pregnancy rates in sheep known to have high numbers of ovulation
