So if if if you if you inject us up a one of a number of channels into some other location and you set up a similar bioelectrical uh pattern, those cells
Will get the message and they'll and they'll make an eye.
But what's really interesting is the thing is that there's actually a competition because
I if if you if you section those eyes, what you find is that there's a few cells that we injected and then they secondarily recruited a bunch of their neighbors to participate in making that eye.
We didn't touch them.
It's a it's a sec, you know, the cells we did inject uh said broadcast uh there needs to be an eye here, and then so so many cells need to sort of cooperate.
But sometimes you do that, and sometimes you get no eye at all.
Because what's happening is there's a competing uh uh interpretation where this which is a cancer suppression mechanism where the surrounding cells are saying, your voltage is wrong, and we're gonna we're gonna equalize you out to us.
They make gap junctions and they try to equal.
So you get this, you get this battle.
So these cells are saying, No, we're gut, and these other cell cells are saying, No, you should be you should be I.
And it's the degree to which we are good or or not good at providing convincing uh interpretations via these these voltage gradients that we can specify a successful eye or something that you can even see.
Sometimes um you can use uh animals that are transgenic for like early eye genes like RICs one or packs six or something.
And so you inject your your RNA and you see like there's eight eight ectopic spots.
You say, Oh, we're gonna have a tadpole with eight eyes.
Well, what you find out is that a bunch of them get get winked out by their neighbors and and you and and you don't get those.
And then some, if you you know, if you do it right, some of them will.
And so so that battle of interpretations, I think, is also really interesting because that that material, it's not a it's not passive matter, it can support things like this, like a like a dip like a debate between different different anatomical, you know, worldviews about what are what are we building here, you know?
Uh uh yeah, I'm I'm I'm on board.
It it makes sense.
