Abstract
Background: In vitro fertilization (IVF) the technique is useful for understanding early mammalian development and maximizing and speeding up genetic improvement in livestock. Genes that function as genetic markers and are involved in the pre-implantation development of embryos may be used to evaluate the quality of an embryo and the expression of these genes is correlated with the timing of embryonic genomic activation. Methods: Maturing the oocytes of bovine, then fertilizing these matured oocytes and finally culturing the fertilized oocytes to develop into embryos. Determined the gene expression of different certain genes HSP70, OCT4, GLUT1, BAX and DNMT1 in these different cell stages of embryos that were produced. Result: The mRNA expression of these genes was estimated after collecting the embryos listed above that were produced by the in vitro technique. The results showed statistically significant differences in the relative abundance between some of the genes mentioned above in each embryo stage. The timing of the zygotic genome activation process (ZGA) can result in differences in gene expression levels between the early embryonic genes in each developmental stage of in vitro-produced bovine embryos.
