Abstract

Early follicle growth and oocyte development is poorly understood and markers of somatic cell differentiation and oocyte development are required to advance knowledge in this area. Observations in our laboratory suggest that insulin like growth factor binding protein-2 (IGFBP-2) may be such a marker of early follicle growth through its ability to regulate intrafollicular IGF bioavailability. We propose to utilise novel in vivo and in vitro model systems to test the hypothesis that temporal changes in the expression and proteolysis of IGFBP-2 are key determinants of preantral follicle growth. These observations will be correlated to the developmental potential of the oocyte and should contribute to the development of technologies for increasing the availability of oocytes from cattle of high genetic merit for subsequent use in IVF and embryo transfer protocols.
