A family member asks the nurse, "What do they mean when they start taking about stem cells?" Which is the nurse's best response? a) Stem cells are specialized in terms of their structure and function. b) Stem cells are undifferentiated cells with the capacity to generate multiple different cell types. c) Stem cells are regulated by specific genes and the type of cell growing next to them. d) Stem cells have a unique characteristic in that they can renew their cell populations continuously.
