- One technique that we use out of many in the lab
is to use engineering tools
to shape the growth of the stem cells.
So if you can imagine, in baking for example,
let's say you're making like a Valentine's Day cake
and you want to create a shape of a heart.
Well, to do that by hand is very difficult, right?
You don't really shape the cake with your hands to do the heart.
You take a mold, and then you can pour your liquid mixture
into that.
Then you put that in the oven to provide some sort of heating
so that it can become a cake, right?
And it'll have that shape of that cake.
So we create the shape
that we want to have ourselves grow into,
and because we're making a narrow tube,
we are interested in creating tubular shapes.
