3 Stem Cell Differentiation-Hematopoiesis The process by which blood cells are formed is hematopoiesis. A stem cell is capable of dividing and producing new cells that go on to become particular types of cells. Stem cells in red bone marrow produce cells that mature into various types of blood cells. A multipotent stem cell, which is made in the bone marrow, divides, producing two other types of stem cells, lymphoid stem cell and myeloid stem cell. The lymphoid stem cell produces two lymphoblasts. These will later mature into B lymphocytes and T lymphocytes. The B lymphocytes are processed in the bone marrow while the T lymphocytes are processed in the thymus. The myeloid stem cell gives rise to the four different cells that go through a number of stages to become red blood cells, platelets, granular leukocytes, and monocytes. The myeloid stem cell produces, the erythroblasts, the megakaryoblasts, the myeloblasts, and the monoblasts. The erythroblasts mature in the red bone marrow to produce the erythrocytes (or red blood cells). Through a process of many divisions, they lose their nucleus and other organelles. This is why they only live 120 days. Likewise, the megakaryoblasts are also produced in the red bone marrow. They too, lose their nucleus and live only 10 days. These cells will mature to active forms called, thrombocytes or platelets. Myeloid stem cells also give rise to the myeloblasts. This cell differentiates into three distinct forms that will specialize to fight infection in the body. These are the basophils, eosinophils and the neutrophils. These three types of white blood cells are categorized as Granular leukocytes because they tend to have granular nuclei that show up in the staining process. The last cell produced by the myeloid stem cell in the red bone marrow is the monoblasts. These, along with the lymphocytes B and T, are categorized as Agranular leukocytes. The monoblasts will divide and produce the mature form, monocytes, the largest white blood cells in the body.

15 Immune System Name: Date: Period: Nonspecific Immunity Specific Immunity (Triggered by Antigens to produce Antibodies) Includes 1. Skin-- 2. Mucus-- 3. Sweat and Tears-- 4. Inflammatory Response a. White Blood Cells (monocytes/phagocytes)-- b. Fever-- 5. Interferons-- Defenses that are not designed to fight a specific disease but ALL diseases Draw an antibody Humoral Response (triggered by surface antigens of pathogens) Includes 1. In Blood and Lymph a. Lymphocytes produce antibodies (B Lymphocytes) 2. Antibodies are Y- shaped proteins that help to destroy pathogens a. Antibodies bind to antigens on the pathogens b. Cause pathogens to clump up 3. Eosinophils and monocytes engulf and destroy pathogens (clumps of antibodies and antigens) Cell Mediated Response (can recognize cells that have been invaded by viruses) Includes 1. A macrophage presents pathogen s antigens to Killer T cell. 2. Killet T cells then divide thru clonal expansion 3. Killer T cells (cytotoxic T cells) kill infected cells to inhibit the reproduction and spread of viruses 4. Helper T cells produce Memory T cells. 5. Memory T cells react like Memory B cells. Permanent Immunity Once the body has been exposed to a particular pathogen, the B and T cells remain capable of producing specific antibodies to that pathogen. The response to a second exposure is rapid and produces a high number of antibodies, thus preventing a second infection. Active Immunity Vaccinations are given in order to cause the body to be prepared for an infection of a particular pathogen. Vaccinations work by injecting a weakened form of the pathogen (or even parts of the pathogen) into the body so that the body will produce antibodies for the specific antigen. Memory B cells are ready to immediately respond to an exposure to the specific pathogen. Vacca = cow.why? Passive Immunity Antibodies produced by other animals for a pathogen are injected into the bloodstream in order to fight off a specific pathogen. 4. B cells can be activated by T cells to turn into Plasma cells. 5. Plasma cells produce and release large numbers of antibodies into the bloodstream. 6. Some B cells become memory cells and can quickly respond if reinfected by same pathogen. (you can t get the same cold twice) (Antigens trigger the immune system to produce antibodies that are specific to the antigen. B cells and plasma cells make the antibodies with the help of Tcells) 6. Suppressor T cells shut down the Killer T cells when job is done. See fig 13.7 Causes body to reject transplanted organs 15

Interferons 3. In the Specific immunity response of cell mediated response, immune cells recognize body cells that have been invaded by. 4. What do killer T cells kill? 5. Which cells shut down the immune response when the pathogen has been killed off? 6. Transplant organ rejection is due to a response. 7. What triggers the Humoral response? 8. What do the B-lymphocytes produce? 9. Antibodies bind to the on the pathogen and cause the pathogens to up. 10. and engulf and destroy the clumped, antibody covered pathogens. 11.
