Abstract/OtherAbstract:
The efficiency of somatic cell reprogramming to pluripotency using defined factors is dramatically affected by the cell type of origin. Here we show that human keratinocytes, which can be reprogrammed at a higher efficiency than fibroblast(1) , share more genes hypermethylated at CpGs with human ES cells than other somatic cells frequently used for reprogramming. Moreover, pluripotent cells reprogrammed from keratinocytes (KiPS) are more similar to ES cells that those reprogrammed from fibroblasts (FiPS) in regards to DNA methylation levels, mostly due to the presence of genes that fail to acquire high levels of DNA methylation in FiPS cells. We propose that higher reprogramming efficiency correlates with the hypermethylation of tissue specific genes, rather than with a more permissive pluripotency gene network.
