single-cell epigenomics

Individual cells, a new epigenomic target

All somatic cells of a body have the same genome. But each of them can present a different gene expression profile depending on the epigenetic marks that, acting as molecular switches, activate or deactivate these sequences. These regulatory systems, globally known as the epigenome, include the chemical modification of the genetic fragments and the histones, or changes in the accessibility and make-up of the DNA.
