“Animal cells share some qualities with plant cells, but one key feature ours lack is a rigid cell wall. While this provides structure for plants, it’s also something scientists are increasingly looking at for use in new materials, cellulose technology and, now, insulin delivery.”
I was kind of skeptical of how this would be useful. There’s no way growing insulin in lettuce is more efficient than growing it in bacteria or yeast. BUT, their lettuce insulin stuff doesn’t require refrigeration, which is obviously a huge advantage.
