Today, most people know at least something about stem cells. Embryonic stem cells enjoy regular mentions in news programs and magazines, probably because of the controversial way in which they are generated but also because of their huge potential in medicine. Here we distinguish between and define types of stem cells, discuss techniques used so far to create various cells and tissues from stem cells, and discuss how three-dimensional supports and stem cells have been and should be used to encourage the development of functional replacement tissue.
