Lee Spievak, 69, chopped off part of his finger - said to be almost down to the first joint - in a model aeroplane accident in 2005. Within weeks, it is said the tip of the finger - including bone, tissue, skin and nail grew back.

Quite an interesting piece. Clearly, the applications of this treatment, if proven to be completely effective, are limitless over time. Imagine the impact this treatment could have on war veterans injured during the course of battle.
