- There are people that have spent years of their life
saying, "We want stem cells
to turn into this one kind of cell."
And they will try everything they can.
Almost like a recipe, you can try,
how many cells should we grow at a time?
What kind of proteins, or if you think of it
almost like a recipe,
what kind of different ingredients should we put in?
How long should we put those in?
There's a lot of different things.
What temperature should we grow them at?
And people will just try a lot of different options,
and depending what kind of cell they want to grow,
you'll find the combination that works best.
