In the United States, food produced from cultured animal cells is regulated jointly by FDA and USDA. FDA oversees cell collection, cell banks, and cell growth and differentiation; USDA's Food Safety and Inspection Service (FSIS) oversees the production and labeling of the meat, poultry, and egg products made from cultured animal cells. The FDA framework is titled "Human Food Made with Cultured Animal Cells," and such products are built from "cultured animal cells."
Pet-food relevance: if cultured-meat / cell-based protein is used in pet food in the US, it falls under this FDA/USDA regulatory framework (and any applicable feed-use authorisation). This is the US analogue to the EU novel-food track for alternative proteins.
