Some call it “cultured (人工培养的)” meat. Others say it’s “fake” meat. What is it? The “meat” is grown by a new technology in the lab. It may show up in the meat sections of our supermarkets someday soon. Cultured meat is produced when cells from animals are “cultured” or grown under lab conditions. It isn’t like plant-based meat substitutes (替代品) made from vegetable protein, since cell-based meat is grown from actual animal cells. This means that it is an animal product, so not suitable for vegetarians. Is cell-cultured meat the same as ordinary meat? That depends on who you talk to. The muscle fibers (纤维) produced in the lab are the same as those found in a steak, say leading researchers in this technology at Maastricht University in The Netherlands.
