Elaine Fuchs, who works in the Laboratory of Mammalian Cell Biology and Development, spoke Friday in Packard and Lewis Laboratory on the development of stem cell research and its ethical concerns.
Nuclear transfer is one of the procedures Fuchs focuses on in her lab.
In this process, the nucleus of an unfertilized egg is removed, discarded and replaced with the nucleus of a skin cell. The cell is then reprogrammed and placed back into the body so it can regenerate.
Embryonic stem cells can generate cells for all tissues of the body, while adult stem cells can only generate a subset of tissues.
“Epidermis cells cannot make liver cells, just as liver cells cannot make epidermis cells,” Fuchs said
