For now it seems you would need a donor body to act as the "scaffolding" for your progenitor cells. Pessimistically, there may one day be a blackmarket for scaffolding cadavers with desirable features. > While the progenitor cells needed to regenerate all of the tissues that make up a limb could be provided by the potential recipient, what has been missing is the matrix or scaffold on which cells could grow into the appropriate tissues. > ... living cells are stripped from a donor organ with a detergent solution and the remaining matrix is then repopulated with progenitor cells appropriate to the specific organ. I wonder if a person could also "upgrade" their body, or invent articulate organs with unique functions, such as printing a scaffolding for wings or a specialized muscle structure attached to the hip for opening beer bottles.
