Question

Quizplus · Accepted Answer

Stem cells for research purposes are usually taken from extra embryos about to be discarded by fertility clinics. This is because embryonic stem cells are pluripotent, meaning they have the potential to differentiate into any type of cell in the body, making them valuable for medical research. However, the fact that these embryos are being destroyed for the purpose of research is a highly debated ethical issue.
