In jellies, the factorsthat we needed to present to them, to cooks appendage regeneration, are simple nutrient factors. One is just a very high amount of food, we think, more than they normally see. And then the growth or o insolin and the amino acid loosin. In flies, we just mixe the amino Acid loosin and the growthormon insolen in their food. Same thing in mice, we mixed a loosin. And in the case of mice, we can't give insolen orally, because, just like inhumans, insolen cannot be administered orally. It gets digested in our so instead of insolin, we just, i

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.
