Synergistic Prostaglandin E Synthesis by Myeloid and Endothelial Cells Promotes Fetal Hematopoietic Stem Cell Expansion in Vertebrates

Researchers showed that in the zebrafish embryo, prostaglandin E2 synthesis genes are expressed by distinct stromal cell populations, myeloid, and endothelial cells of the caudal hematopoietic tissue.
