As I understand it your technology is in part about providing a scaffolding that enables normal animal cells to grow. But there's a question that I genuinely think is important, but risk sounding like a troll. The qualities of a successful cancerous cell, to grow without restraint, unimpeded by the density of other cells or whether the cell is attached to a surface, will probably be even more successful in a bio-reactor than they would be in an organism where unconstrained growth will undermine the health of the the animal and the supply of energy and nutrients to the cell. This leads me to wonder whether cells with cancer like qualities - deranged karyotypes and unregulated cell division will become common in meat cell cultures. Does this seem reasonable? Is it a health issue, or do we perhaps not know yet? It's certainly a bit creepy.

Some thoughts. Tumors in muscular tissue are relatively rare. The growth cycle in these bioreactors should be short, giving less probability of runaway mutations. It’s a hyper growth medium with supernatural levels of growth hormones, so tumors may actually be favored. Are tumoral mammal cells integrated by humans when infested raw?

In humans eating another species? It seems unlikely, but ingestion of live cells is one of the mechanisms have been proposed for the transmission of Devil Facial Tumour Disease, in which live cancer cells are transferred between individual Tasmanian Devils.

(just so you know before clicking it's pretty nasty) https://en.wikipedia.org/wiki/Devil_facial_tumour_disease

a tumor burger? doesnt sound very appetizing.
I encountered tumors in regular meat of many varieties multiple times. For some reason, pork has the biggest probability of tumors.
