Abstract:Hematopoiesis occurs in the liver and the bone marrow during murine development. Newborn mice with a ubiquitous deletion of IκBα develop a severe hematological disorder characterized by an increase of granulocyte/erythroid/monocyte/macrophage colony-forming units (CFU-GEMM) and hypergranulopoiesis. Here, we provide evidence that this particular myeloproliferative disturbance is mediated by continuously deregulated perinatal expression of the Notch ligand Jagged1 in IκBα-deficient hepatocytes.
