Chapter 23, Problem 19BS
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?

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
Sickle Cell Anemia
Sickle cell anemia is a prevalent disease, which usually is seen in the African American community. It is an inherited disease where both parents have a copy of the gene and pass it along to offspring.

She tells you that her daughter is not doing well after switching from breast milk to a solid diet, and has started to grow pale and is sleeping all the time. You find that her height and weight are way below normal. A blood test reveals the hyper segmentation of neutrophil cells, an indicator of bone marrow malfunction. You deduce that she has pernicious anemia, and refer her to an experienced doctor.

- Imagine you are a surgeon. 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. All five happen to have the same rare blood type, so it is hard to find the right donor. At this time, a foreign traveler came to the hospital for a simple body check. 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_forwardJonah and Jana are siblings.

Bone marrow transplant was not an option at that time and so blood transfusion was the treatment of choice. Please explain the reasoning behind these other signs and symptoms that Curie experienced? Thank you!arrow_forwardWhy are stem cells not more abundant in the human body? I learned that stem cells can proliferate into any kind of cell in the body. These cells can be very beneficial for repairing damaged tissues and replacing dead tissue. So, if stem cells have so many uses and benefits why are they not more abundant in the human body? What are the benefits and risks of an increase of stem cells? Do the benefits outweigh the possible problems? Is an increase in stem cell numbers only worth while when an injury has occurred such as in stem cell therapy? Thank youarrow_forward
