HSCI researchers extend human epigenomic map

New research by the Harvard Stem Cell Institute’s Alex Meissner, published online as a letter in the journal Nature, describes the dynamics of DNA methylation across a wide range of human cell types. Chemically, these marks are the addition of a methyl group — one carbon atom surrounded by three hydrogen atoms — anywhere a cytosine nucleotide sits next to a guanine nucleotide in the DNA sequence.
