This scanning electron microscopic (SEM) image revealed some of the comparative ultrastructure between normal red blood cells (RBCs), and a sickle cell RBC (left) found in a blood specimen of an 18-year-old female patient with sickle cell anemia, (HbSS). People who have this form of sickle cell disease, inherit two sickle cell genes (S), one from each parent. HbSS is usually the most severe form of the disease. See PHIL 11690 for a colorized version of this image. Sickle cell disease encompasses a group of inherited RBC disorders. Healthy RBCs are round, and move smoothly through blood vessels. In sickle cell disease, the RBCs become hard, and sticky, and look like a C-shaped farm tool called a sickle. The sickle cells die early, which causes a constant shortage of RBCs. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems.
