In Vitro Growing Immature Porcine Oocytes

Porcine ovaries contain a large number of oocytes at different stages of growth, most of which degenerate either before or at various stages of growth. To utilize those potential female gametes stored in the ovary, it is important to develop culture system that can provide a suitable alternative environment for oocytes to achieve full growth and competences to undergo meiotic maturation, fertilization, and embryonic development. Several culture systems have been developed for the porcine oocytes, and studies have demonstrated that a proportion of the oocytes grown in vitro can acquire the competence to undergo meiotic maturation.
