Interleukin‐4 Supplementation During In Vitro Culture Modulates the Expression of Stress‐ and Immune‐Related Genes During Porcine Blastocyst Development
ABSTRACT The aim of this study was to evaluate the effect of supplementing in vitro culture medium of porcine zygotes with interleukin‐4 (IL‐4) on their developmental competence and quality. Cumulus‐oocyte complexes (COCs) were matured and fertilized in vitro. The presumptive zygotes were then cultured in vitro for 7 d...
