Magnified 3500X, this digitally colorized scanning electron microscopic (SEM) image revealed some of the ultrastructure displayed by red blood cells (RBCs) from a 6-year-old male patient that has sickle cell with hereditary persistence of fetal hemoglobin (S-HPFH). The persistent fetal hemoglobin reduces the severity of the consequences of the sickle cell disease, thereby, reducing the degree of cellular deformity, or sickling. 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.
