- So people in the past have been able to study
what the kind of cells that we want to make,
so in our case, artery cells, what those are like
when they actually come out of a human body,
so we know what we're trying to do.
So that might mean what kind of proteins are on there,
what do the cells look like, how do they act?
And then we can run tests to see if our cells do the same things.
Then we try and put them on something,
like a long tube, and we say, "Can they stick there?"
Y'know, 'cause if they're not gonna stay around,
that's gonna be a problem in the body.
Then we can look at things like using some animal studies,
eventually studies in humans, and the way that
we usually figure out if the artery's working
is actually an ultrasound.
So the same way you might see,
if you've seen a picture of like a baby before it's born,
we can use those same sort of pictures
and we can see, is there blood flowing through that artery,
or does it get stopped somewhere?
