Legend: A regulatory triad predicted from correlation analysis of gene expression in single bone marrow stem and progenitor cells was validated experimentally.  Gfi1 and Gfi1b are mutually inhibitory, while Gata2 can activate expression of Gfi1b, and Gfi1 can repress expression of Gata2.

Legend: 48 genes were measured in nearly 4000 single cells from 4 distinct anatomical stages during the development of blood in the mouse embryo.  Hierarchical clustering identified three major clusters based on gene expression: I, early mesodermal cells; II, haemogenic endothelium; III, early blood cells.  Coloured bar indicates embryonic stage of origin.  Blue, primitive streak; green, neural plate; orange, head fold; red, 4 somite Runx1-GFP+; purple, 4 somite, Flk1+ Runx1-GFP-.

Plain English

My PhD project has been interested in understanding how transcription factors regulate cell fate in the haematopoietic system. Much of what we know about transcription factors comes from population studies, but cell fate decisions are made at the level of individual cells. I have therefore been interested in using single cell gene expression analysis to understand the structure and function of transcriptional networks at the single cell level in adult haematopoiesis and during blood development in the embryo.
