However  there is little information about ontogenetically distinct neutrophil populations. In this work  using a photoconvertible transgenic zebrafish line; Tgmpx:Dendra2  we selectively label rostral blood island derived and caudal hematopoietic tissue derived neutrophils in vivo during steady state or upon injury. By comparing the migratory properties and single cell expression profiles of both neutrophil populations at steady state we reveal that rostral neutrophils show higher csf3b expression and migration capacity than caudal neutrophils. Upon injury  both populations share a core transcriptional profile as well as subset specific transcriptional signatures. Accordingly  both rostral and caudal neutrophils are recruited to the wound independently of their distance to the injury. While rostral neutrophils respond uniformly  caudal neutrophils respond heterogeneously. Collectively  our results reveal that co existing neutrophils populations with ontogenically distinct origin display key functional differences.
