Due to early embryonic lethality of Gata2 deficiency in mice  its role during adult hematopoiesis is incompletely understood. In zebrafish  mammalian functions of Gata2 are split between two orthologues: Gata2a and Gata2b. Previous studies have shown that Gata2b is prominently expressed in hematopoietic stem and progenitor cells HSPCs  whereas Gata2a is mainly expressed in the vasculature. We found that Gata2b deficient zebrafish have a reduction in embryonic definitive HSPC numbers and have impaired myeloid lineage differentiation  but are viable. This allowed us to study the role of Gata2b in adult hematopoiesis. To assess the impact of Gata2b deficiency on the transcriptional profile of HSPCs and differentiated cells  we sorted the entire progenitor and HSPC population including the lymphoid population from kidney marrow KM of WT and germline Gata2b deficient zebrafish based on scatter profiles and processed for single cell RNA sequencing. To enrich the scarce HSC population  we used pooled KM from two WT and Gata2b deficient TgCD41:GFP zebrafish per sample and included all CD41:GFPlow expressing cells present in the kidney marrow pool as these cells were shown to contain transplantable HSCs.", "ENA FIRST PUBLIC:2022 04 09|ENA LAST UPDATE:2022 04 09", null, "Protocols: Adult zebrafish were euthanized  kidney marrow was isolated and dissociated by pipetting in PBS/10% FCS. 7 AAD 7 amino actinomycin D 0.5mg/L BD biosciences was used for live/dead discrimination.
