Fanconi anemia (FA), the most common inherited bone marrow failure syndrome, is traditionally attributed to postnatal stem cell loss. Using Fancc-deficient mouse models, we demonstrate a prenatal deficit in fetal liver hematopoietic stem and progenitor cells (HSPCs), including reduced repopulating capacity and cell cycle arrest. Increased γH2AX foci and upregulation of DNA repair genes indicate heightened susceptibility to DNA damage absent external stressors. These findings suggest congenital defects in hematopoiesis contribute to FA pathogenesis, highlighting the fetal hematopoietic compartment as a critical target. 000002724 540__ $$fCC BY 000002724 542__ $$fIn copyright - single owner 000002724 650__ $$aFetal Development$$035918 000002724 650__ $$aHematopoietic Stem Cells$$020016 000002724 650__ $$aFanconi Anemia$$018886 000002724 650__ $$aObesity$$023118 000002724 650__ $$aCongenital Bone Marrow Failure Syndromes$$013196 000002724 650__ $$aChild$$016462 000002724 650__ $$aHematopoietic System$$020017 000002724 650__ $$aDiet, High-Fat$$039538 000002724 691__ $$aSchool of Medicine$$041369 000002724 692__ $$aDepartment of Cell, Developmental and Cancer Biology$$041399 000002724 7001_ $$aKamimae-Lanning, Ashley$$uOregon Health and Science University$$041354 000002724 7201_ $$aKurre, Peter$$uOregon Health and Science University$$041354$$7Personal$$eAdvisor$$eMentor 000002724 8564_ $$93e5fa659-bbfa-4116-8020-fd25ee6f5413$$s1979336$$uhttps://digitalcollections.ohsu.edu/record/2724/files/3465_etd.pdf$$ePublic$$29df50840c50acd36c8ca4ddcce3c98e4$$31 000002724 905__ $$a/rest/prod/j9/60/20/75/j96020756 000002724 909CO $$ooai:digitalcollections.ohsu.edu:2724$$pstudent-work 000002724 956__ $$aGet Accessible Copy$$uhttps://ohsu.libwizard.com/f/requestaccessibledocument 000002724 980__ $$aTheses and Dissertations
