Final answer:
Using stem cells to grow new organs D. reduces the risk of rejection by the recipient.
Step-by-step explanation:
Stem cells are undifferentiated cells with the unique ability to develop into various specialized cell types. They play a crucial role in tissue regeneration, growth, and repair in multicellular organisms. Two main types are embryonic stem cells, derived from embryos, and adult stem cells, found in various tissues, both holding potential for therapeutic applications.
The benefit of using stem cells to grow new organs is that it reduces the risk of rejection by the recipient. Stem cells can be derived from the patient's own body, which means that the new organs would contain the patient's own cells. This reduces the chances of the recipient's immune system seeing the organ as foreign and triggering rejection.
