Proteomes of Animal Oocytes : What Can We Learn for Human Oocytes in the In Vitro Fertilization Programme?

Abstract EN

Oocytes are crucial cells for mammalian reproduction, yet the molecular principles underlying oocyte development are only partially understood.

Therefore, contemporary proteomic approaches have been used increasingly to provide new insights into oocyte quality and maturation in various species such as mouse, pig, and cow.

Especially, animal studies have helped in elucidating the molecular status of oocytes during in vitro maturation and other procedures of assisted reproduction.

The aim of this review is to summarize the literature on mammalian oocyte proteome and secretome research in the light of natural and assisted reproduction and on lessons to be learned for human oocytes, which have so far remained inaccessible for proteome analysis.
