Abstract

This study was conducted to examine the potential for implantation and sustainable fetal development of mouse embryos cultured from the pronuclear to blastocyst stage. Pronuclear embryos from ICR mice (Harlan Sprague-Dawley) were cultured in Sydney IVF sequential media (Cook) to the blastocyst stage in medium only or co-cultured with autologous cumulus cells. We also experimented with co-culture in 100 mu L drops. Drop co-culture produced blastocyst formation rates with a mean of 47.0%, which was significantly higher (P < 0.05) compared to embryos cultured in identical culture conditions except without cumulus cells at 27.3%. Blastocysts obtained in vitro in Cook medium only and co-cultured in Cook medium with cumulus cells were transferred to pseudopregnant females of ICR strain. The day of blastocyst transfer into surrogate females was designated as post-transfer of blastocyst day 1 (PT 1). The implantation and fetal development was compared to embryo transfer of in vivo derived blastocysts, which served as controls. There were no statistical differences for implantation and fetal development rates for blastocysts cultured in vitro in either Cook medium only or co-culture in Cook medium with cumulus cells compared to in vivo-derived blastocysts. The advantage of the co-culture system is in generating more blastocysts available for transfer.
