WebUsing nonhuman primate models, Nash et al. show that maternal Western-style diet provokes reprogramming of fetal hematopoietic stem and progenitor cells to transmit pro-inflammatory memory to myeloid cells for years after weaning, even when offspring are fed a conventional diet, predisposing these offspring to inflammatory disease across the lifespan. WebDuring fetal development, hematopoiesis occurs in multiple waves throughout the developing embryo and fetus, including extraembryonic yolk sac (YS), the para-aortic region of the embryo, fetal liver, and placenta before eventually homing to the bone marrow where it occurs just before birth.
