Which stem cell type is primarily used to treat blood and immune system diseases because it can form red blood cells, white blood cells, and platelets?

• A. Hematopoietic stem cells
• B. Embryonic stem cells
• C. Neural stem cells
• D. Mesenchymal stem cells

Answer: (A)

Hematopoietic stem cells have the ability to generate all blood components: red blood cells, white blood cells, and platelets. This makes them the primary option for treating blood and immune system diseases, because they can reconstitute the entire blood-forming system after treatments like chemotherapy or radiation. They reside in the bone marrow and can be collected from bone marrow, peripheral blood, or umbilical cord blood for transplantation, rebuilding the patient’s immune and circulatory capacity. Embryonic stem cells are pluripotent and can become many cell types, but they are not the standard therapy for blood diseases due to ethical considerations and immune compatibility issues. Neural stem cells produce cells of the nervous system, not blood components, so they don’t address blood or immune system diseases. Mesenchymal stem cells differentiate into bone, cartilage, or fat and support tissue repair, but they do not efficiently reconstitute the blood and immune system.
