Stem Cells In Medicine Flashcards

All 7 cards in this deck

Give two benefits of treating a patient with stem cells made from the patient's own skin cells.: Embryos or a donor are not needed, and the cells match the patient's tissue type so there is less chance of rejection.
Give two risks of stem cell therapy.: The new cells may not function correctly; the stem cells may continue to divide (cell division could develop into cancer). Also possible: side effects or rejection of the cells.
Which type of cell would stem cells be made to differentiate into in order to treat type 1 diabetes?: Insulin-producing cells of the pancreas, replacing the patient's faulty cells.
Which type of cell would stem cells be made to differentiate into to treat paralysis caused by a damaged spinal cord?: Nerve cells, to replace the damaged nerve cells in the spinal cord.
How could stem cell therapy spread a disease to a patient?: Donor stem cells could carry a virus that goes undetected, and the patient who receives them would then be infected.
Give one ethical objection to using embryonic stem cells in research.: The embryo is destroyed, and some people believe each embryo is a potential human life.
How can adult stem cells be used to cure sickle cell anaemia?: By a bone marrow transplant: the donor's adult stem cells make new, healthy blood cells.
