Colony-stimulating factors are hormones that regulate hematopoiesis. Erythropoietin (Epogen), secreted by the kidney, increases bone marrow erythropoiesis. Granulocyte colony-stimulating factor (G-CSF) stimulates bone marrow leukopoiesis. The most recent colony-stimulating factor is thrombopoietin (TPO), which acts on bone marrow to promote the growth of platelets. These hormones are now produced biosynthetically by recombinant DNA techniques and have shown some impact in the prevention of chemotherapy-induced neutropenia, treatment of cytopenias associated with myelodysplasias, and aplastic anemia. 1. What is erythropoietin? A. A...

Practice Questions 61 15. A patient had a bone marrow transplant and numerous blood transfusions during the course of treatment for cancer. A bone marrow biopsy performed to monitor for recurrence a few weeks after treatment ended, showed abundant hemo siderin within macrophages.

Based on this A) leave the cell cycle in a Go phase, after exiting G1 B) reverse from G2 to G, C) leave the cell cycle in a G3 phase, which immediately follows 2- D) continually cycle but simply fail to go through cytokinesis. E) halt in the midst of the S phase. CEDT

Spitting up blood 2. What do the lab data tell about RBCs? A. None of the tests reflect information...
immunology: Indicate what step is correct (Select all that apply) Lymphocytes travel through the body in the lymph as well as the blood Lymphocytes leave the blood through the walls of fine capillaries in 2ry lymphoid organs After spending some time in the LN, lymphocytes leave in the efferent lymph Lymphocytes return to blood at the subclavian vein A lymphocyte after encounter an antigen to which its receptor binds, stops recirculating. The spleen has no connection to the lymphatic system...
