Chapter 23, Problem 16BS
A 12-year-old girl will die from leukemia if she does not get a bone marrow transplant, but a matching donor cannot be found. A newborn’s umbilical cord contains blood-forming stem cells, which can be harvested after birth and donated. The girl’s parents decide to have another child in a final attempt to provide their daughter with a matching donor. Doctors report that having a “savior sibling” is not uncommon. In your opinion, is it acceptable to have a child in order to save another child’s life? Why or why not?

Students have asked these similar questions
Which of the following statements is NOT correct about the umbilical cord?
Select one:
a. Preserving the baby’s umbilical cord can be useful to help a sibling who may need stem cell transplant.
b. The amount of blood cells contained in the umbilical cord is too little to treat an adult for stem cell transplant.
c. A baby’s umbilical cord can be used to treat the same baby, if they are born with blood disorders, such as leukemia.
d. The umbilical cord blood cells are multipotent, not totipotent like embryonic stem cells.
In the hospital you are caring for a 6-year-old girl with leukemia. The mother says the physicians want to do a bone marrow transplant. She asks you to explain to her what a bone marrow transplant is because she was so upset when the physician told her. She wants to know if she can be a donor or if a friend can be a donor. Explain the types of bone marrow transplant to the mother.
One year after their first son was born, a couple gave birth to twins, a boy and a girl. At the age of three, one of the twins was diagnosed with leukemia, and he needed a bone marrow transplant. Who is most likely to be a good donor? What if the parents had banked the twins’ cord blood? Explain

Five patients in the hospital are in urgent need of different organ transplants to survive. One of them needs a heart, one a lung, one a liver, and the other two each a kidney.

By chance, he has the same rare blood type as theirs. With your expertise, as long as you use some simple medication to end the life of the traveler painlessly and without the notice of others, then his organs can save the five people awaiting organ transplants What would you do? Would you kill one person to save five people?arrow_forward
