Erythropoiesis from pluripotent stem cells is very complex, and mirrors that observed in developmental erythropoiesis, with primitive and definitive waves. For a better understanding of their potential for their use in blood transfusion, they were compared to erythropoiesis from cord derived CD34 haematopoietic stem cells.

View SamplesDuring development a specialised subset of endothelial cells, the haemogenic endothelium, undergo an endothelial-to-haematopoietic transition. This process critically involves the transcription factor Runx1. Here we have isolated a specific subpopulation of endothelial cells using a Runx1 enhancer-reporter transgenic mouse line (23GFP). We have compared the gene expression profile of this population to non-23GFP expressing endothelial cells and CD41 expressing haematopoietic progenitor cells to assess whether 23GFP expression marks a biologically distinct subset of endothelium.
Early dynamic fate changes in haemogenic endothelium characterized at the single-cell level.
