During embryonic development, undifferentiated stem cells accumulate methyl groups and other epigenetic marks that funnel them into one of the three germ layers, each of which gives rise to a different set of adult tissues.
The specific pattern of epigenetic marks in a cell type specifies identity and this epigenetic control is vital to what makes our cells different, for example a skin cell from a liver cell, when they all contain the same genetic instructions.
The current work shows that changes in the genetic code of a particular gene can control epigenetic marks at different genes, implying that a gene's genetic code can affect whether other genes are turned on and off, which makes it important to understand the function of all genes involved, not just the one with the so - called misspelling.
Our results support the well - known fact in different mammalian species that IVC increases the transcription at blastocyst stage of a large number of genes, suggesting a decrease in repressive epigenetic marks [7, 44].
