TranscriptomicsThe transcriptional program controlled by Runx1 during early hematopoietic development (expression data)
Transcription factors have long been recognised as powerful regulators of mammalian development, yet it is largely unknown how individual key regulators operate within wider regulatory networks. Here we have used a combination of global gene expression and chromatin-immunoprecipitation approaches a...

GenomicsThe transcriptional program controlled by Runx1 during early hematopoietic development (ChIP-seq data)
Transcription factors have long been recognised as powerful regulators of mammalian development, yet it is largely unknown how individual key regulators operate within wider regulatory networks. Here we have used a combination of global gene expression and chromatin-immunoprecipitation approaches a...

GenomicsCombinatorial Transcriptional Control in Blood Stem/Progenitor Cells: Genome-wide Analysis of 10 major Transcriptional Regulators
Combinatorial transcription factor (TF) interactions control cellular phenotypes and therefore underpin stem cell formation, maintenance and differentiation. Here we report the genome-wide binding patterns and combinatorial interactions for 10 key regulators of blood stem/progenitor cells (Scl/Tal1,...

GenomicsThe Transcriptional Programme Controlled by Scl/Tal1 Gene during Early Embryonic Haematopoietic Development
The basic-helix-loop-helix transcription factor Scl/Tal1 controls the development and subsequent differentiation of haematopoietic stem cells (HSCs). However, since few Scl target genes have been validated to date, the underlying mechanisms have remained largely unknown. Here we have employed ChIP...

GenomicsHigh-throughput single cell gene expression analysis in primary blood stem and progenitor cells identifies new links between key transcriptional regulators
Cellular decision-making is mediated by a complex interplay of external stimuli with the intracellular environment, in particular transcription factor regulatory networks. Here we have determined the expression of a network of 18 key haematopoietic transcription factors (TFs) in 597 single primary ...

GenomicsA fully validated blood stem/progenitor cell regulatory network reveals mechanisms of cell state stabilisation
The aim of this study was to determine the genomic binding sites of important haematopoietic transcription factors in haematopoietic cell lines. 416Bs cells were fixed with either 1 or 0.4 % formaldehyde for 10 mins. Chromatin was isolated, sonicated for 7 mins (30 sec on, 30 sec off), and specific ...

TranscriptomicsMyeloid-biased HSC require Semaphorin 4A from the bone marrow niche for self-renewal under stress and life-long persistence
Tissue stem cells are hierarchically organized, but the signals that selectively preserve their functional integrity are largely unknown. Semaphorin 4A (Sema4A) is a specific regulator of myeloid-biased hematopoietic stem cells (myHSC), which are positioned at the top of the HSC hierarchy. Through...

GenomicsGenome-scale expression and transcription factor binding profiles reveal therapeutic targets in transgenic ERG myeloid leukemia
Here we show that pan-haematopoietic ERG expression driven by the Vav promoter induces an early progenitor myeloid leukemia in transgenic mice. Integrated genome-scale analysis of gene expression and ERG binding profiles revealed that ERG activates a transcriptional program similar to human AML stem...
