Scientists use genomic tools to create maps of DNA methylation

(PhysOrg.com) -- 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.
