Three molecular stages are required for reprogramming the DNA methylome. Stage 1: Recruitment. The enzymes needed for reprogramming are recruited to genome sites that require demethylation or methylation. Stage 2: Implementation. The initial enzymatic reactions take place. In the case of methylation, this is a short step that results in the methylation of cytosine to 5-methylcytosine. Stage 3: Base excision DNA repair. The intermediate products of demethylatio… WebMay 9, 2024 · The reprogramming process frequently generates aberrantly methylated regions that are dissimilar to the somatic donor cell and the human ESCs ( Lister et al., 2011 ): these represent a class of differentially methylated regions (DMRs) that is specific to the reprogrammed cells.
