Is the bioreactor density assuming a single-cell suspension system? If a "classical" stirred tank bioreactor is used, there is likely a different max cell density for that than a custom reactor meant for adherent cell culture.

Maybe also just worth flagging that genetic editing is great and maybe even necessary in order to make cells suitable for cultivated meat bioprocesses, but it can introduce a big metabolic burden to the cells that impact growth rate/differentiation if you ask them to do too many things at once. The cell has to make tradeoffs and sometimes engineering causes unexpected downstream cascades that maybe need to be considered? I agree though, adaptation and engineering will be needed (possibly in conjunction) for cultivated meat cell lines.
