The more we know about the process, the more we're able to form a hypothesis. And in this case, based on what we find, that simple nutrient factors, te high amount of nutrient factors, can coax latent regeneration to emerge. It might be some energetic offt so perhaps the a conditions that we require for re that is permissive for regeneration, is also a condition that isa permissive for tenser development,. Of course, we don't know this for sure, but we can start thinking, making hypothesis along this direction.
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.
