... refers to an experimental process conducted in a culture dish, where new ES cells are generated to study in culture. The distinction between these two procedures is that reproductive cloning refers to the gen 11818 1 www.pnas.org/cgi/doi/10.1073/pnas.1834433100 oration of whole animals, whereas therapeutic cloning refers to the generation of cells entirely in a culture dish.
