Regrowing Body Parts

A hobby shop owner called Lee Spievack accidentally cut his fingertip while working. his brother, who is a research scientist sent him this powder to sprinkle on his wounded finger. 4 weeks later the finger regrow itself complete with all blood vessels nerves and bones. the powder contained a substance called the active matrix- harvested from pig's bladders - which tells the body cells where to go and what to form in case of injury.

researchers say that soon regrowing whole body organs will be possible. i think this is a break through. may be soon we won't need organ donating any more.
