by a large number of human genes. We developed a strategy to study the coordinate
regulation of such genes, and to compare different cell populations or tissues. A set of 150
genes, comprising different classes of epigenetic modifiers was compiled. This new tool was
used initially to characterize changes during the differentiation of human embryonic stem
cells (hESC) to central nervous system neuroectoderm progenitors (NEP). qPCR analysis …
