| Impact | ||||||||||||||||||||||||||||||||||
| When it comes to using embryonic stem cells, there is a controversy over the idea of an embryo and a potential life. Is an embryo a person? According to the International Society for Stem Cell Research, "There is no test for whether an embryo is a person. Instead we are left to our own devices, to our own moral reasoning." | ||||||||||||||||||||||||||||||||||

| How old of an embryo are scientists willing to study? | ||||||||||||||||||||||||||||||||||
| Considering that the embryos being studied are donated by fertilization clinics, and they will never enter a uterus, scientists can study an embryo ranging from a few days old to a few weeks old. According to National Institute of Health, "Pluripotent stem cells are isolated from human embryos that are a few days old. Pluripotent stem cell lines have also been developed from fetal tissue (older than 8 weeks of development)." | ||||||||||||||||||||||||||||||||||
