  • FBS doesn’t contain cells. It’s a chemical/protein mixture used to grow various cell cultures. On It’s own it doesn’t do anything. It just contains most of the things that growing cells need.

    I actually know very little about it though. Check out The Thought Emporium on youtube if you want a better look at how it is all done. They do all sorts of fun stuff like engineering yeast to produce spider silk, growing neurons and using them for basic computation, making a meat berry, and using a genetically engineered virus to cure their lactose intolerance for a while.

    Edit: Also that youtuber did some testing on replacing FBS and the growth medium with other substances with some sucess. If I remember correctly, they found that for growing regular muscle cells they could replace like 60% of the FBS needed with egg yolk without harming the cells. But that’s still an animal product so it’s still not exactly vegan.

    I’m not arguing the philosophy. It’s a wonderful idea. As someone who regularly drives a stick shift I very much wish that it would work. But like many wonderful ideas it doesn’t survive contact with actual humans. In any large city if there is a car length open in front of your vehicle then someone will be zipping into it. I’ve had people do that while we’re traveling at 65mph let alone in slow moving traffic. If you keep sitting there and letting people go in front of you until there is room then you will not move and you will probably get shot by one of the people stuck behind you. It’s like if you were at the grocery store durring a busy time and you kept telling people to go in front of you then you wouldn’t be able to check out until everyone was gone.
