An exceptionally high serum erythropoietin (EPO) activity was documented in an anephric patient with severe anemia who required transfusions every 4 weeks. The patient's serum EPO was comparable to normal human urinary EPO in the polycythemic mouse assay and was neutralized by an antiserum against EPO. The patient's serum inhibited EPO stimulated-heme synthesis by normal human marrow cells in vitro. This finding suggests that an inhibitor played an important role in causing the anemia of this uremic patient.

D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
