The identification of mature and immature blood cells in peripheral blood smears and bone marrow preparations is fundamental to the laboratory diagnosis of haematological disorders. Here, you may review the mature and immature white cells to gain more practice and confidence in their identification.
A blood stem cell may become a lymphoid stem cell or a myeloid stem cell. A lymphoid stem cell becomes a white blood cell. A myeloid stem cell becomes one of three types of mature blood cells: 1  Red blood cells that carry oxygen and other substances to all tissues of the body.n a patient with a myelodysplastic syndrome, the blood stem cells (immature cells) do not become mature red blood cells, white blood cells, or platelets in the bone marrow. These immature blood cells, called blasts, do not work the way they should and either die in the bone marrow or soon after they go into the blood.
