Sickle cell anaemia. Coloured scanning electron micrograph (SEM) of red blood cells in sickle cell anaemia (drepanocytosis). Here, normal red blood cells (rounded) contrast with an elongated sickle- shaped cell (top) & other irregular-shaped cells. Sickle cell anaemia is an inherited blood disease, so-called because the affected red blood cells have abnormal haemoglobin (an oxygen-carrying pigment) that distorts cells into a sickle shape. Due to this defect, sickle cells are fragile......
