CELLS AND HUMORAL (ANTIBODY-MEDIATED) IMMUNITY   This response is carried out by antibodies, which are produced by B lymphocytes activated into  plasma cells. B cells (B lymphocytes) develop from stem cells located in red bone marrow. After  maturation in the bone marrow, the B cells migrate to lymphoid tissue such as lymph nodes or  the spleen. Each B cell is programmed to recognize a particular antigen and has specific antigen  receptors located on the surface of its plasma membrane. When the antigen for which the B cell  is specific comes along, with the assistance of T cells, the B cell will react in two ways: It will divide into a clone of many cells specific to the same antigen as the original B cell The clone of cells will change into antibody-secreting plasma cells
