Fig. 3. Reduced histone H3K9 trimethylation in SCNT embryos treated with TSA and VC. (A) Immunostaining analysis indicated that SCNT embryos with TSA+VC showed a significantly lower level of H3K9me3 compared to control embryos. Reduced histone H3K9 trimethylation in SCNT embryos treated with TSA and VC. (A) Immunostaining analysis indicated that SCNT embryos with TSA+VC showed a significantly lower level of H3K9me3 compared to control embryos. Different letters indicate statistical significance (P<0.05, one-way ANOVA with subsequent Tukey's multiple comparison tests). Fourteen or fifteen two-cell embryos were examined. Error bars represent means±s.e. (n=3). (B) A model shows how the treatment with trichostatin A and vitamin C in the dBSA-containing medium enhances epigenetic reprogramming and results in the enhanced cloning success rate.
