The same strategy that we found worked in jelly fish worked as well in ah the fruit flitresopila, in coaxing limb to re grow in fruit flies. And finally, in in in mouse. That's it in the mice. Have to clarify that the mouse digit is our model to explore how to induce,. if we can induce limb regeneration in human short, short of amputation.

Biological organisms are pretty good at healing themselves, but their abilities fall short in crucial ways. Planaria can be cut into pieces, and each piece will regrow into an entire organism; but for most advanced animals, loss of a limb becomes a permanent condition. But why should that necessarily be so, if an organism’s genome knows what it’s supposed to look like? Lea Goentoro’s lab has recently produced surprising results that indicate that it’s easier than you might think to coax animals into regenerating limbs.
