The Transcriptional Programme Controlled by Scl/Tal1 Gene during Early Embryonic Haematopoietic Development

ABSTRACT: 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-Seq technology to generate a genome-wide catalogue of Scl binding events in a stem/progenitor cell line followed by validation using primary fetal liver cells and comprehensive transgenic mouse assays. Transgenic analysis provided in vivo validation of multiple new direct Scl target genes and allowed us to reconstruct an in vivo validated network consisting of 17 factors and their respective regulatory elements. By coupling ChIP-Seq in model cell lines with in vivo transgenic validation and s
