What about stem cells?

Since stem cells can develop into various new types of cells, the research into stem cells is of great interest because of the possibility for use in organ donation. A great deal of research is now carried out on so-called bio artificial organs, or organs that are ‘grown’ with human cells in a shell of collagen (scaffolds). This type of organ takes time to develop and any results or light at the end of the tunnel won’t be seen for another ten years.
