ABSTRACT
The article discusses the challenges to the creation of human-animal hybrid embryos which has been proposed as a way to generate embryonic stem-cells (SC) without having to rely on human eggs. Topics include an overview of research by Robert Lanza and colleagues, published in "Cloning Stem Cells," from the stem-cell company Advanced Cell Technology showing that the hybrid embryos failed to grow beyond 16 cells and did not properly express genes important in pluripotency.
