In humans heterozygous germline mutations in GATA2 often lead to a loss of function of one allele causing GATA2 haploinsufficiency. In mice Gata2 has an essential regulatory function in hematopoietic stem cell HSC generation and maintenance. However whereas Gata2 null mice are lethal at embryonic day E 10.53 Gata2 heterozygous Gata2+/ mice survive to maturity with normal blood values. However mouse models thus emerged as a useful source to identify the function of GATA2 in HSC generation and fitness they leave the mechanisms causing the different aspects of GATA2 deficiency syndrome largely undiscovered. Zebrafish have the advantage of having two GATA2 orthologues; Gata2a and Gata2b. Gata2a is expressed predominantly in the vasculature and is required for programming of the hemogenic endothelium. Gata2b is expressed in hematopoietic stem/progenitor cells HSPCs and homozygous deletion gata2b / redirects HSPCs differentiation bias thus mimicking one of the GATA2 haploinsufficiency phenotypes found in patients. But patients carry heterozygous rather than homozygous GATA2 mutations we specifically focused on how heterozygous Gata2b mutations could be mechanistically linked to erythro myelodysplasia a major clinical hallmark of GATA2 patients. To investigate the mechanisms of heterozygous GATA2 mutation caused GATA2 deficiency syndrome we created a heterozygous gata2b mutation zebrafish model and sorted the entire progenitor and HSPC population including the lymphoid population from kidney marrow KM of WT and mutated zebrafish based on the scatter profile of flow cytometry for single cell RNA scRNA sequencing.", "ENA FIRST PUBLIC:2024 11 05|ENA LAST UPDATE:2024 11 05", 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.

Understanding the role of eosinophils in these processes requires a better understanding of eosinophilopoiesis. Using a zebrafish model we have identified an eosinophil lineage specific marker eslec. Using this marker we have established a Tgeslec:eGFP reporter line which specifically labels zebrafish eosinophil lineage cells from early life through maturity. Spatial temporal analysis of eslec+ cells demonstrated organ distribution at the larval stage. By single cell RNA Seq of eslec+ cells tissue distributed eosinophils were found to have similar differentiation paths but different tissue specific expression profiles. Genetic analysis demonstrated a Cebp1 and Cebp\u00df transcriptional axis that regulated eosinophilopoiesis in which Cebp1 directly targeted cebpb to inhibit eosinophil differentiationthe commitment and differentiation of the eosinophil lineage. In summary this study characterized eosinophil development in multiple dimensions including spatial temporal patterns expression profiles and genetic regulators. The results provide for a better understanding of eosinophilopoiesis. Overall design: For scRNA Seq analysis of eosinophils in kidney eosinophils were sorted from adult Tgeslec:eGFP kidneys.

Understanding the role of eosinophils in these processes requires a better understanding of eosinophilopoiesis. Using a zebrafish model we have identified an eosinophil lineage specific marker eslec. Using this marker we have established a Tgeslec:eGFP reporter line which specifically labels zebrafish eosinophil lineage cells from early life through maturity. Spatial temporal analysis of eslec+ cells demonstrated organ distribution at the larval stage. By single cell RNA Seq of eslec+ cells tissue distributed eosinophils were found to have similar differentiation paths but different tissue specific expression profiles. Genetic analysis demonstrated a Cebp1 and Cebp\u00df transcriptional axis that regulated eosinophilopoiesis in which Cebp1 directly targeted cebpb to inhibit eosinophil differentiationthe commitment and differentiation of the eosinophil lineage. In summary this study characterized eosinophil development in multiple dimensions including spatial temporal patterns expression profiles and genetic regulators. The results provide for a better understanding of eosinophilopoiesis. Overall design: For scRNA Seq analysis of eosinophils in kidney eosinophils were sorted from adult Tgeslec:eGFP kidneys.
