Final answer:
In hematopoiesis, a greater number of pluripotent stem cells differentiate into erythrocytes compared to leukocytes, with typically about 30% becoming leukocytes and 70% erythrocytes.
Step-by-step explanation:
In hematopoiesis, pluripotent stem cells in the bone marrow differentiate into various types of blood cells, including leukocytes (white blood cells) and erythrocytes (red blood cells). Although a precise percentage can vary, typically a far greater number of erythrocytes are produced compared to leukocytes. This is because leukocytes are less numerous in the body, with typically only 5000 to 10,000 per µL of blood, and erythrocytes are the most abundant formed element in blood.
While myeloid stem cells give rise to erythrocytes, megakaryocytes that produce platelets, and a myeloblast lineage that gives rise to various forms of granular leukocytes such as neutrophils, eosinophils, and basophils; lymphoid stem cells give rise only to lymphocytes (B cells, T cells, and NK cells), which are a type of leukocyte. Lymphocytes account for about 20-30 percent of all leukocytes. Therefore, the correct answer to what percentage of pluripotent stem cells become leukocytes and erythrocytes would be (C) 30% leukocytes, 70% erythrocytes.
