What happened in the vegan community?

I hadn’t heard about any of this until seeing that ToS post.

    Not yet. Growing cells in a lab still requires fetal bovine serum which is obviously an animal product. There is work going into replacing it with a synthetic alternative but, to my knowledge, noone has been successful yet.

      You seem knowledgeable, is the FBS clonal? Like can it grow more undifferentiated or does it need to be continually harvested?

        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.
