According to the [[National Heart, Lung, and Blood Institute]], '''Aplastic Anemia''' (a-PLAS-tik uh-NEE-me-uh) is "a rare and serious blood disorder in which bone marrow stops making enough new blood cells. Bone marrow––the spongy material inside bones—makes new blood cells called stem cells. Stem cells normally develop into three main types of blood cells: [[red blood cell]]s, [[white blood cell]]s, and [[platelet]]s. Each type of blood cell has its own functions in the body." | According to the [[National Heart, Lung, and Blood Institute]], '''Aplastic Anemia''' (a-PLAS-tik uh-NEE-me-uh) is "a rare and serious blood disorder in which bone marrow stops making enough new blood cells.
