Correcting Sickle Cell Disease using Stem Cells Essay

Correcting Sickle Cell Disease using Stem Cells - Essay Example The pattern of inheritance of sickle cell anemia is autosomal recessive. That means the symptoms will only possibly manifest if both parents are carrier of hemoglobin A. However, at present, the only available long term treatment for the disease is bone marrow transplant, which is prone to rejection and subsequent immune system reaction. The goals of other treatments, blood transfusion and pain medicines, are only for short-term relief of symptoms (Zieve and Chen, 2011). Recently, however, researchers from Johns Hopkins have found another plausible long term treatment for sickle cell anemia. By inserting the correct hemoglobin A gene to pluripotent bone marrow cells and removing the defective hemoglobin S, the patient can be able to produce RBCs that have the correct type of gene (Science Daily, 2011). Despite this new breakthrough in treatment, this does not prevent inheritance of the disease, because the gene to be transferred to an offspring is contained in sex cells, and not the bone marrow cells that are to be fixed using the new technology recently
