Studies in an early development window unveils a severe HSC defect in both murine and human Fanconi anemia [human]

Project description:We performed a unique kinetics study of hematopoiesis in Fancg-/- mouse embryos, between E12.5 and E14.5 developmental window. We also report for the first time that a deep HSC defect is also observed during human FA development, and that human FA FL HSCs present a transcriptome profile similar to that of mouse E12.5 Fancg-/- FL HSCs.

Studies in an Early Development Window Unveils a Severe HSC Defect in both Murine and Human Fanconi Anemia.

Project description:Fanconi anemia (FA) causes bone marrow failure early during childhood, and recent studies indicate that a hematopoietic defect could begin in utero. We performed a unique kinetics study of hematopoiesis in Fancg-/- mouse embryos, between the early embryonic day 11.5 (E11.5) to E12.5 developmental window (when the highest level of hematopoietic stem cells [HSC] amplification takes place) and E14.5. This study reveals a deep HSC defect with exhaustion of proliferative and self-renewal capacities very early during development, together with severe FA clinical and biological manifestations, which are mitigated at E14.5 due to compensatory mechanisms that help to ensure survival of Fancg-/- embryos. It also reports that a deep HSC defect is also observed during human FA development, and that human FA fetal liver (FL) HSCs present a transcriptome profile similar to that of mouse E12.5 Fancg-/- FL HSCs. Altogether, our results highlight that early mouse FL could represent a good alternative model for studying Fanconi pathology.

Pluripotent cell models of Fanconi anemia identify the early pathological defect in human hemoangiogenic progenitors

Project description:Fanconi anemia (FA) is a disorder of genomic instability characterized by progressive bone marrow failure (BMF), developmental abnormalities and an increased susceptibility to cancer. Although various consequences in hematopoietic stem/progenitor cells have been attributed to FA-BMF, the quest to identify the initial pathological event is still ongoing. To address this issue, we established induced pluripotent stem cells (iPSCs) from fibroblasts of six FA patients with FANCA mutations. An improved reprogramming method yielded iPSC-like colonies from all patients, and iPSC clones were propagated from two patients. Quantitative evaluation of the differentiation ability demonstrated that the differentiation propensity toward the hematopoietic and endothelial lineages is already defective in early hemoangiogenic progenitors. The expression levels of critical transcription factors were significantly downregulated in these progenitors. These data indicate that the hematopoietic consequences in FA patients originate from the early hematopoietic stage, and highlight the potential usefulness of iPSC technology for elucidating the pathogenesis of FA-BMF. The investigation of the RNA-seq analysis of iPSC-derived HAPCs.
