Figure 6. The effect of embryo aggregation on transcription levels of embryonic development-related genes.

Figure 6

Real-time PCR results for (A) pluripotent related genes (Oct4, Sox2, Nanog, Cdx2), (B) apoptosis related genes (Bax, Bak, Bcl-xl, Bcl2) and (C) implantation related genes (VEGF, IFNG, LIF) at blastocysts in the indicated groups. All genes were normalized with the GAPDH gene. (*P < 0.05). For all panels, n indicates number of embryos examined. Re = 3. 1X; one zona-free embryo, 3X; three zona-free embryos.
