| abstractText | During embryonic development, muscle tissues, skin, and a subset of vascular endothelial cells arise from Pax3-expressing embryonic progenitors defined as paraxial mesoderm. By contrast, haemogenic potential is well established for extra-embryonic mesoderm and intra-embryonic lateral plate mesoderm, which do not express Pax3. To date, it is not known whether the haematopoietic system also contains Pax3 lineage cells. Here, we show that the mouse foetal liver and foetal circulation contain a transient population of Pax3 lineage cells with hallmarks of haematopoietic progenitors and the potential to generate both myeloid and erythroid cells. We propose that Pax3 lineage haematopoietic cells should be investigated to better understand normal haematopoietic development from different mesodermal derivatives. Further, genetic alterations of Pax3 lineage haematopoietic cells should be investigated for their potential to cause haematopoietic malignancies. |
