Xtensive embryonic defects observed in SCNTs and controls, their EE tissues were related, suggesting that they’re significantly less affected by the SCNT process and that their defects contributed much less to pregncy loss at Day. Indeed, with their high rate of productive elongation and couple of DEGs, Day EE tissues looked standard irrespective of their somatic origin.

At earlier developmental stages, however, abnormal molecular patterns have been detected in morulae from abnormal SCNT Low conceptuses. Abnormal Day phenotypes may thus appear during postblastocyst differentiation. E and EE functioning would therefore be altered andor uncoupled, compromising development to term. The contrasting phenotypes observed within the SCNT Low and High groups raise concerns about the epigenetic status of EEE tissues and bovine fibroblasts. Indeed, recent work in mice highlights the importance of early epigenetic marks linked to epiblast size, gastrulation characteristics, and EEE relationships.
