GenomicsGC-rich Sequence Elements Recruit Polycomb Repressive Complex 2 (PRC2) in ES cells
Polycomb proteins are epigenetic regulators that localize to developmental loci in the early embryo where they mediate lineage-specific gene repression. In Drosophila, these repressors are recruited to sequence elements by DNA binding proteins associated with Polycomb repressive complex 2 (PRC2). Ho...

TranscriptomicsCETCh-Seq of Mammalian Transcription Factors
Chromatin immunoprecipitation followed by next-generation DNA sequencing (ChIP-seq) is a widely used technique for identifying transcription factor (TF) binding events throughout an entire genome. However, ChIP-seq is limited by the availability of suitable ChIP-seq grade antibodies, and the vast m...

TranscriptomicsTranscription profiling of human umbilical cord blood and adult bone marrow CD34+CD33-CD38-Rho(lo)c-kit+ cells to identify candidate regulators of HSC self-renewal versus differentiation fate decisions
The global gene expression profiles of human umbilical cord blood and adult bone marrow CD34+CD33-CD38-Rho(lo)c-kit+ cells, enriched for hematopoietic stem/progenitor cells (HSC) with CD34+CD33-CD38-Rho(hi) cells, enriched in committed hematopoietic progenitor cells (HPC), were compared to identify ...

GenomicsMapping polycomb complexes in human and mouse embryonic stem cells
In embryonic stem (ES) cells, bivalent chromatin domains with overlapping repressive (H3 lysine 27 tri-methylation) and activating (H3 lysine 4 tri-methylation) histone modifications mark the promoters of more than 2000 genes. To gain insight into the structure and function of bivalent domains, we m...

TranscriptomicsTranscription profiling of mouse ES cells, neural precursor cells and embryonic fibroblasts
Expression profiles for isogenic (129SvJae x C57BL/6) murine embryonic stem (ES) cells, neural precursors (NPC) obtained through in vitro differentiation of the ES cells, and embryonic fibroblasts (MEF) obtained at day 13.5. Experiment Overall Design: 3 replicates of wt ES cells, 3 replicates of wt...

GenomicsGenome-wide maps of chromatin state in pluripotent and lineage-committed cells
Genome-wide maps of chromatin state (H3K4me3, H3K9me3, H3K27me3, H3K36me3, H4K20me3) in pluripotent and lineage-committed cells We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells. By obtaining over four b...
