Blood lines from embryo to adult

Article Abstract:

A study to determine if the blood formation (haematopoiesis) in mammalian embryos and adults has separate origins or a common source was conducted. The adult blood-forming cells are separately generated in the aorta-gonad-mesonephros (AGM) region and later seed the adult bone marrow, and the adult blood forming cells in the AGM region at least partly originate from Runx1-positive progenitors in the yolk sac.
