Stem cells make more of themselves by self-renewing cell divisions. In the February 1, 2011, issue of Genes & Development, Taoudi and colleagues (pp. 251-262) show an essential role for the ETS transcription factor ERG in the self-renewal of embryonic hematopoietic stem cells. A model is presented in which the redundant functions of GATA2 and RUNX1 in self-renewal are under direct control of ERG.

The Zon laboratory aims to dissect how assaults to the hematopoietic system cause severe diseases such as leukemias, lymphomas, and anemias. They investigate hematopoietic development and disease using chemical screens, genetic screens, and analysis of novel transgenic lines in zebrafish.
