You know, the concept of printing has been around for a long time. Because we were actually talking about printing the scaffolds and materials, right? So it didn't take much of a leap to say, "OK, let's just not print the materials, but let's print the materials and the cells together."
And of course to do so, the challenge was, well, we know we can print ceramics, right? We can print auto parts, right? The doorknobs in your car get printed very much in that way many times. So the challenge was, if we're going to create these structures, how do you make sure that the cells that you put in survive? And that's really a lot of the work that we ended up having to do, making sure that we could deliver cells through a printing cartridge and allow them to survive and be functional.
