Episode notes

i want to emphasize right now or model this the mouse digit in a digit. And it's a digit because it's a gentler amputation. We don't want to start experimenting on limb directly. But that's the hope that now wil be have. Is like i set a told into the problem, and now we can start understanding the mechanisms. If we understand the mechanisms, then we can engineer it to be better. That's the hope. And if we're lucky, then maybe we can make leaps aheadright? I mean, what was so? The experiments are all right. So that's, once in defence of optimism,. But i think it will take a lot of efforts

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.
