The benefits of using stem cells conditions. e Stem cells are useful in studying how cell/division goes wrong (suchas cancers). ® Stem cells could be used to grow new organs for transplantation in the future. The risks and objections of using stem cells There is a risk of transferring viral infections by using stem cells.
