I was curious when you posted that. I went digging. For some reason, no one wanted to post it anywhere, but I found someone who did.
Animal welfare is one reason for producing lab-grown meat. This production method can produce meat without the need for raising and slaughtering a large number of animals and therefore, has the potential to increase animal welfare within the food system.
2 However, the process currently still relies on stem cells obtained from a live animal, and the most widely used
culture medium contains fetal bovine serum (FBS), which is collected from foetal blood at animal slaughterhouses, so it is not yet entirely slaughter-free.

I wonder how much blood has to be spilled to grow a pound of this meat?
