Researchers Map Cells' Inner Landscapes

Summary:

Much of the field of stem cell biology and development remains uncharted territory. Just as famous explorers and astronomers mapped out landmasses and constellations, researchers are working fervently to chart the molecular landscapes within stem cells -- especially embryonic stem cells. A clearer understanding of the cells’ unique properties, particularly their ability to give rise to nearly any type of cell, could unlock fundamental questions about biology and may even spur novel ways to treat disease. A team of researchers at the Broad Institute has helped break new ground in stem cell research through work described in two recent Nature papers. The most recently published study, appearing in the July 6 advance online issue, involves an effort to map regions of cells’ genomes marked by DNA methylation — one of several so-called ‘epigenetic’ modifications.
