Conclusions
X-Chromosome inactivation has been used as a tool to follow the reprogramming process. We have used immunostaining and western blot as methods to follow this reprogramming qualitatively and quantitatively.
Methods
Recent evidence suggests that 3-deazaneplanocin A (DZNep) is a global histone methylation inhibitor which selectively inhibits trimethylation of lysine 27 on histone H3K27, and it is an epigenetic therapeutic for cancer. The characteristics of DZNep lead us to hypothesize that it is a good candidate to epigenetically reprogram hESCs to the Class I. Additionally, we used sodium butyrate (NaBu) shown in previous studies to up-regulate the expression of germ cell specific markers (these sentences should be come in introduction).
Results
We used these two drugs to produce epigenetically stable hESC lines. hESC lines are an appropriate system for disease modeling and understanding developmental stages, therefore producing stable stem cell lines may have an outstanding impact in different research fields such as preventive medicine. Conclusions: X-Chromosome inactivation has been used as a tool to follow the reprogramming process. We have used immunostaining and western blot as methods to follow this reprogramming qualitatively and quantitatively.
