چکیده (انگلیسی):

Objective: To determine the efficacy of embryo outgrowth on fibronectin as a low cost,
high throughput alternative to embryo transfer to model embryo attachment and the initial
stages of implantation.
Methods: Following in vitro embryo culture, embryo quality was assessed via embryo
transfer or embryo outgrowth with metabolic assessment.
Results: This study shows that blastocysts attach to fibronectin at the same rate that they
implant in vivo, and that the carbohydrate utilisation of embryos that successfully
outgrow is comparable to those that are able to develop into a fetus.
Conclusions: Embryo outgrowth is a suitable alternative endpoint to embryo transfer.
