Which of the following reasons explains a possible advantage of using adult stem cells in therapeutic cloning rather than embryonic stem cells?
A) Adult stem cells have a longer lifespan in culture than embryonic stem cells, and would persist for a longer time in the patient's body.
B) Embryonic stem cells would not be able to enter the correct tissue of the patient's body, unlike an adult stem cell.
C) Adult stem cells must be obtained from another individual before being injected into the patient, and would be less likely to be rejected by the patient's body.
D) Embryonic stem cells may stop dividing within the patient's body once injected, unlike adult stem cells.
E) Adult stem cells may be obtained from the patient and would be less likely to be rejected by the patient's body.
