Abstract: The development of vertebrate definitive hematopoiesis is featured by temporally and spatially dynamic distribution of hematopoietic stem/progenitor cells (HSPCs). It is proposed that the migration of definitive HSPCs, at least in part, accounts for this unique characteristic; however, compelling in vivo lineage evidence is still lacking. Here we present an in vivo analysis to delineate the migration route of definitive HSPCs in the early zebrafish embryo. Cell-marking analysis was able to first map definitive HSPCs to the ventral wall of dorsal aorta (DA). These cells were subsequently found to migrate to a previously unappreciated organ, posterior blood island (PBI), located between the caudal artery and caudal vein, and finally populate the kidney, the adult hematopoietic organ. These findings demonstrate that the PBI acts as an intermediate hematopoietic organ in a manner analogous to the mammalian fetal liver to sustain definitive hematopoiesis before adult kidney hematopoiesis occurs. Thus our study unambiguously documents the in vivo trafficking of definitive HSPCs among developmentally successive hematopoietic compartments and underscores the ontogenic conservation of definitive hematopoiesis between zebrafish and mammals. © 2007 by The American Society of Hematology.
