It seems the most common method to acquire starter cells is by taking a cell sample from a live animal, which can be performed using minimally invasive methods or by biopsying a recently slaughtered animal where the tissue is still viable

- colinhb 3y agoDifferent issue -- the medium that the cells grow and multiply in has FBS as constituent. Most of the cultured meat companies rely on it, though upstream there are a number of companies working to develop "serum-free" media with the goal of selling into the cultured meat companies. It's also an active area of academic research, since FBS is not a chemically-defined product, it introduces variability into cell-culture protocols.
