Nucleated red blood cell nucleated RBCs are found only in the circulation of fetuses and newborn infants. After infancy, RBCs normally only contain a nucleus during the very early stages of the cell's life, and the nucleus is ejected as a normal part of cellular differentiation before the cell is released into the bloodstream. Thus, if NRBCs are seen on an adult's peripheral blood smear, it suggests that there is a very high demand for the bone marrow to produce RBCs, and immature RBCs are being released into circulation.
