Genomic binding profile of TAL1 in human Endothelial Colony-Forming Cells

ABSTRACT: Endothelial colony-forming cells (ECFCs) have been reported as promising cells for regenerative medicine thanks to their angiorepair properties. Transcription factors are primary determinants of the functional capacity of the cells and TAL1 has been shown as a critical regulator of endothelial lineage in both development and adult life. However, only few (three) TAL1 targets have been identified so far in mouse and human endothelial cells. This ChIP-seq experiment was designed to identify genome binding/occupancy of TAL1 by ChIP and high throughput sequencing in primary human endothelial stem/progenitor cells. TAL1 ChIP and IgG ChIP (negative control) were performed in crosslinked ECFCs derived from human umbilical cord blood.

A major goal of cell therapy for vascular diseases is to promote revascularization through the injection of endothelial stem/progenitor cells. The gene regulatory mechanisms that underlie endothelial progenitor-mediated vascular repair, however, remain elusive. Here, we identify the transcription factor TAL1/SCL as a key mediator of the vascular repair function of primary human endothelial colony-forming cells (ECFCs). Genome-wide analyses in ECFCs demonstrate that TAL1 activates a transcription  ...[more]
