A North Carolina startup found a way to grow real leather from cow cells in a lab, a sustainable breakthrough that could cut emissions and eliminate slaughter in the $400 billion leather industry.
“Cell lines can be collected from a primary source, i.e., through a biopsy on an animal under local anesthesia. They could also be established from secondary sources such as cryopreserved cultures (cultures frozen after previous research)”
And even if it were, it would at the very least reduce the amount of cow killing necessary as you get more meat per cow since meat can be grown. I also dont know how many times stem cells can be reused but they are often reused as indicated in the above quote.
You talking about the stem cells or cell lines? If so thats not true from what I read: https://en.wikipedia.org/wiki/Cultured_meat
