Ovine Granulosa Cells Isolation and Culture to Improve Oocyte Quality

Abstract

The functional cooperation between the oocyte and its surrounding granulosa cells is mandatory to oocyte growth and acquisition of developmental competence in mammalian species. Availability of in vitro methods for culture granulosa cells is important in understanding the biology of these cells and the response of maturing oocyte to in vitro culture and co-culture. Using the ovine as a model the ensuing chapter describes methods for primary culture of ovine granulosa cells and their co-culture with theca cells or oocytes that allow to mimic the molecular interactions between somatic cells and maturing oocyte and improve oocyte quality.
