Single-Cell Analysis Identifies Distinct Stages of Human Endothelial-to-Hematopoietic Transition
During development, hematopoietic cells originate from endothelium in a process known as endothelial-to-hematopoietic transition (EHT). To study human EHT, we coupled flow cytometry and single-cell transcriptional analyses of human pluripotent stem cell-derived CD34(+) cells. The resulting transcriptional hierarchy showed a continuum of endothelial and hematopoietic signatures. At the interface of
