  1. Therapeutic uses of stem cellsBy Mishi & STEPHANIE

  2. Stem cells found in the bone marrow give rise to the red blood cells, white blood cells and platelets in the body. These stem cells can be used in bone marrow transplants to treat people who have certain types of cancer. • When a patient has cancer and is given high doses of chemotherapy, the chemotherapy kills the cancer cells but also the normal cells in the bone marrow. This means that the patient cannot produce blood cells. So before the patient is treated with chemotherapy, he or she can undergo a bone marrow harvest in which stem cells are removed from the bone marrow by using a needle which is inserted into the pelvis (hip bone). Bone marrow transplants

  3. Alternatively, if stem cells cannot be used from the patient then they can be harvested from a matching donor. After the chemotherapy treatment the patient will have a bone marrow transplant in which the stem cells are transplanted back into the patient through a drip, usually via a vein in the chest or the arm. These transplanted stem cells will then find their way back to the bone marrow and start to produce healthy blood cells in the patient CONT…

  4. CONT… • Therefore the therapeutic use of stem cells in bone marrow transplants is very important as it allows some patients with cancer to undergo high chemotherapy treatment. Without this therapeutic use of stem cells, patients would only be able to take low doses of chemotherapy which could lower their chances of curing the disease.

  5. Extracting stem cells from those that are already born which can be used for that individual in order to avoid any immune system reaction. • Stem cells reproduce. Therefore, it is necessary to remove the “new” developed stem cell for use somewhere else in the body or anywhere else. Therapeutic Cloning*

  6. Adult stem cell therapy for treating heart disease was commercially available in at least five continents at the last count . • Possible mechanisms of recovery include: • Generation of heart muscle cells • Stimulation of growth of new blood vessels to repopulate damaged heart tissue • Secretion of growth factors • Assistance via some other mechanism • It may be possible to have adult bone marrow cells differentiate into heart muscle cells.
