In a first attempt (top), researchers removed an egg's genetic material and replaced it with the genes from an adult skin cell. These embryos didn't grow. The researchers tried another method: They left the egg's original genetic material in, but then also added genetic material from an adult cell (bottom). These embryos started growing.
Researchers in New York are reporting an advance in creating cloned human embryos. The embryos would not be used for reproduction, but rather the creation of embryonic stem cells. Many scientists believe that human embryonic stem cells made this way could revolutionize medicine.
The advantage of stem cells made this way is that they could be personalized to an individual.
