    ANIMAL & CELL MODELS
  • SEC23B-deficient mice die perinatally, exhibiting massive pancreatic degeneration, with this early mortality limiting evaluation of the adult hematopoietic compartment, but SEC23B-deficient hematopoietic stem cells (HSC) do not exhibit a disadvantage at reconstituting hematopoiesis when compared directly to wild-type HSC in a competitive repopulation assay
