In April 2014, scientists reported that cloning technologies have been used to generate stem cells that are genetically matched to adult patients. They were able to put the nucleus of an adult skin cell inside an egg, and that reconstructed egg went through the initial stages of embryonic development. These findings might lead to future studies in
A) organ transplants
B) cosmetic plastic surgery
C) how endangered species survive in the wild
D) development of artificial limbs for amputees
