A couple who is expecting their first child has been advised by friends to consider harvesting umbilical cord blood in order to have a future source of stem cells
The couple has approached their caregiver with this request and is seeking clarification of exactly why stem cells are valuable and what they might expect to gain from harvesting it. How can their caregiver best respond to the couple's enquiry? Stem cells can
A)
"help correct autoimmune diseases and some congenital defects."
B)
"be used to regenerate damaged organs should the need ever arise."
C)
"be used as source of reserve cells for the entire blood production system."
D)
"help treat some cancers and anemias, but they must come from your child himself or herself."
Ans:
C
Feedback:
The proliferative potential and self-renewal of stem cells make them a compensatory mechanism and reserve source for the entire hematopoietic system. While they could be of possible use in certain autoimmune conditions or in cases of organ failure, these statements do not capture their essence. Stem cells can also come from a histocompatible donor.
