Abstract
Objective: Some reports have indicated that conditioned medium from growing mouse embryonic stem cells (ESCs) provides a supportive condition for small follicles growing, oocyte maturation, and following embryo growth. The aim of this study is assessing in vitro maturation (IVM) and consequent in vitro fertilization (IVF) outcome of immature mouse oocytes using human embryonic stem cells conditioned medium (HESCM).
Materials and methods: In this experimental study, 240 germinal vesicle (GV) oocytes were took from NMRI female mice, aged 4-6 weeks, 48 hours before injection of 5 IU pregnant mare serum gonadotropin (PMSG). 120 GV oocytes without cumulus cells were cultured in each of the groups. 120 GV were cultured in HESCM as test groups and also 120 GV cultured in human embryonic stem cells medium (HESM) as control groups. After evaluating the metaphase II (MII) oocyte maturation rate at 8, 16 and 24 hours, the MII oocytes subsequently were fertilized in vitro and the two-cell embryo development rate was recorded at days 1, 2, and 3. Statistical analysis was performed by using the generalized estimating equations (GEE) method that calculated their rate ratio.
Results: Our data indicated there are significant differences between the maturation rates in HESCM and HESM (P=0.004), also the two-cell embryo development was significant between two culture media (P=0.00).
Conclusion: Similar to some other studies, the secretome of the HESCM showed a significant impact on the IVM outcomes in mice.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
