Article Abstract

Signaling pathways and transcription factors are involved in porcine embryonic development. Here, we demonstrate that glycogen synthase kinase-3 (GSK3) inhibitor, CHIR99021 and recombinant porcine interleukin-6 (rpIL6) significantly promote porcine parthenogenetic blastocyst formation (49.23 ± 8.40% vs 32.34 ± 4.15%), with increased inner cell mass (ICM) cell numbers (7.72 ± 2.30 vs 4.28 ± 1.60) and higher expression of pluripotent genes, such as OCT4, SOX2 and NANOG. Furthermore, CHIR99021 and rpIL6 improve blastocyst quality with increased blastocyst hatching percentage (16.19 ± 1.96% vs 10.25 ± 1.12%) and subsequently porcine pluripotent stem cells (pPSCs) derivation efficiency. These results advance the understanding of porcine pre-implantation development and provide evidences in improving the blastocyst quality.
