Brief description Genes down-regulated in day 6 embryoid bodies derived from embryonic stem cells (ES) with HEX [GeneID=3087] knockout.
Full description or abstract The first hematopoietic and endothelial progenitors are derived from a common embryonic precursor termed the hemangioblast. The genetic cascades that regulate the differentiation of the hemangioblast to hematopoietic and endothelial cells are largely unknown. In general, much of embryonic development is coordinately regulated by temporal and spatial expression of transcription factors, such as the Homeobox (Hox) gene family. We and others isolated a divergent homeobox gene termed Hex (or Prh) that is preferentially expressed in hematopoietic and endothelial cells. Using in vitro Hex-/- embryonic stem (ES) cell differentiation, in vivo yolk sac hematopoietic progenitor assays, and chimeric mouse analysis, we found that Hex is required for differentiation of the hemangioblast to definitive embryonic hematopoietic progenitors and to a lesser extent endothelial cells. Therefore, Hex is a novel regulator of hemangioblast differentiation to hematopoietic and endothelial cells.

We need your help: Update on GSEA/MSigDB funding support

Last November we submitted a proposal to NCI's Information Technology for Cancer Research (ITCR) program for the continued funding of GSEA and MSigDB. Unfortunately, our proposal was not funded in this round, but we were encouraged to resubmit for the next one. This funding is critical for our continuing support and enhancement of the GSEA-MSigDB resource.

For our original submission many of you sent us emails of support, an important requirement for these grants. We now ask for your help again. We would greatly appreciate a short email message from you describing how the resource has been of value to your work and any concerns you may have about its continued availability.

Please send us your message of support to on or before Monday June 5, 2023.

Thanks in advance for your help and support.
The GSEA/MSigDB Team.
