      You use a device called a bioreactor. There are many types of bioreactors, but to stretch cells, you have to have two important parts. You need a stretchy surface for the cells to attach to, and then you need something to stretch that surface. I use two different bioreactors. The first grips the surface and pulls it. The second uses a vacuum to pull at the surface and make it stretch.
