Abstract

Conservation of the vertebrate body plan has been attributed to the evolutionary stability of gene-regulatory networks (GRNs). We describe a regulatory circuit made up of Gata2, Fli1, and Scl/Tal1 and their enhancers, Gata2-3 , Fli1 +12, and Scl +19, that operates during specification of hematopoiesis in the mouse embryo. We show that the Fli1 +12 enhancer, like the Gata2-3 and Scl +19 enhancers, targets hematopoietic stem cells (HSCs) and relies on a combination of Ets, Gata, and E-Box motifs. We show that the Gata2-3 enhancer also uses a similar cluster of motifs and that Gata2, Fli1, and Scl are expressed in embryonic day-11.5 dorsal aorta where HSCs originate and in fetal liver where they multiply. The three HSC enhancers in these tissues and in ES cell-derived hemangioblast equivalents are bound by each of these transcription factors (TFs) and form a fully connected triad that constitutes a previously undescribed example of both this network motif in mammalian development and a GRN kernel operating during the specification of a mammalian stem cell.

  • A recursively wired triple feedback circuit has been proposed as a kernel underlying the pluripotential state of endothelial/hematopoietic precursors that arise in vertebrate development.

  • The haematopoietic stem cell sub-circuit consists of three positively active genes, has no cross-regulating repressors, and its three genes are linked by multiple positive auto- and cross-regulatory linkages.

    “This sub-circuit consists of three positively active genes. There are no cross-regulating repressors in this sub-circuit, and the three genes are linked by multiple positive auto- and cross-regulatory linkages.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
