Episode notes

A limb represents the complex challenge of regrowing a complex organ. What we learn from regoing a limb can help us with enhancing the regeneration of multiple tissues. That's the dream in viologyis like to make it more like physics, wher it's more the driven, rather than observation driven,. And then once we have that, the ability to predict it.

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.
