Progesterone Promotes In Vitro Maturation of Domestic Dog Oocytes Leading to Successful Live Births.

ABSTRACT: Gene-edited dogs are promising models for biomedical research because they have hundreds of genetic diseases that are similar to humans. A common method for producing gene-edited dogs is assisted reproductive technology (ART) using in vivo oocytes or embryos, but it is much more inefficient and has a higher cost. ART for dogs has lagged mostly because of the lack of an efficient in vitro maturation system. Because early maturation of canine oocytes occurs in follicles with extremely high concentrations of progesterone (P₄), we hypothesize that P₄ has an important role during maturation. In this study, we obtained ovaries of female dogs and collected cumulus-oocyte complexes, which were cultured in vitro in microdrops containing different P₄ concentrations (
