Umbilical cord blood is a rich source of stem cells. Which possible advance in biology would most likely be a result of performing research with an individual’s banked cord blood?

Banked umbilical cord blood contains the donor’s stem cells, which can be studied for ways to replace damaged or diseased cells. Because the cells come from that individual, they could be used to develop a personalized cell replacement therapy for the donor. The other choices involve cancer cells, unrelated donor tissue, or vitamin production, which do not follow as directly from using the donor’s cord blood.
