Is There a Commercially Viable Approach to Tissue Culturing?

The U.S. Department of Agriculture just recently in the fall of 2022 approved some tissue culturing chicken products as okay for consumers. There's still a number of scientific hurdles that need to be overcome before tissue culturing approaches to cellular agriculture, I think, will get into the mainstream. For example, once you've biopsied an animal to get the stem cells and you've separated out the stem cells, you put those stem cells into this nutrient-rich broth. That broth is very, very expensive right now and very, very hard to scale at volume.
