curing disease

• medicine already uses adult stem cells to cure diseases. for example, stem cells transferred from the bone marrow of a healthy person can replace faulty blood cells in a patient
• Embryonic stem cells could be used to replace faulty cells in sick people. you could make insulin producing cells for people with diabetes, nerve cells for people paralysed by spinal injuries.
• in therpeutic cloning, an embryo could be made to have the same genetic information as the patient. stem cells produced from it could have the same genes and wouldnt be rejected by the patients body
• there are risks involved in using stem cells in medicine. e.g stem cells grown in a lab could become contaminated with a virus which could be passed on to the patient and make them sicker
