Figure 2From: Improved blastocyst development of single cow OPU-derived presumptive zygotes by group culture with agarose-embedded helper embryosAgar chip-embedded slaughterhouse helper embryo coculture for ovum pick-up (OPU) presumed zygotes. IVF: slaughterhouse in vitro embryo production system. Ovals show OPU (red) and agar chip-embedded IVF (yellow) zygotes in a 50 μL droplet. Circles represent blastocysts developed from OPU (red) or IVF (yellow) zygotes.Back to article page
