Clearly they aren't confident that these aren't cancer and won't spread in humans. One paper? A couple of people who agree? "Virtually impossible." Did they forget about COVID-19 and how uncredible scientists are now? EDIT: Another thing, they apparently have hybrid meats, with a small percentage of this fake stuff. So you can get all the benefits of immortalized cells with your real meat, and pay about the same! > **The Big C: Why Cultivated Meat Cells Are Not Cancer Cells** > > Outside of the world of science, an average person might associate the concept of cellular immortality with cancer. However, cancer is a distinctly different process than the one used to create immortal cells for cultured meat. > > **How Do Believer Meat’s Immortalized Cells Differ from Cancer Cells** > > Cancer cells have very well defined hallmarks. Cancer cells lack the ability to repair their DNA from damage. Cancer cells' genetic material is unstable. Cancer cells can form tumors and invade tissues in the body. > > Believer Meat’s immortal cells are different. Our cells retain their ability to repair their DNA from damage. Our cells are genetically stable and have maintained that stability for over 1,000 generations. And finally, our cells can’t form tumors or invade tissues in the body. > > How do we know this? Because our scientists and their collaborators at the Hebrew University of Jerusalem ran a plethora of tests that were published in a high profile peer-reviewed paper in the prestigious journal Nature Food. In short, we found that our immortalized cells cannot form tumors, that they repair broken DNA very well, and lack any cancer-related mutations. > > **Why People Cannot Get Cancer From Cells Used in Cultivated Meat** > > Both independent experts and scientists at Believer Meats make clear that there is no way humans could get cancer from animal cells used to make cultivated meat — or even from eating an actual animal that had cancer. Here's what some experts have said on this topic: > > Lucas Smith, an assistant professor in the College of Biological Sciences and School of Medicine at the University of California-Davis told USA Today that it would be “virtually impossible” for someone to get cancer even if they ate meat from an animal with cancer, and that we "know much more about the genetic makeup of cultivated meat cells than what we currently ingest from traditional meat." > > Robert Weinberg, a renowned Massachusetts Institute of Technology biologist and cancer researcher, told Bloomberg that “it’s essentially impossible for a cell from one species to gain a foothold in the tissues of another species...So even if one were to take highly malignant cells from a cow and drink them, I don’t see what the problem would be.” > > Our own scientists explain that cells used to make our meat would be "very dead" before they ever reached a consumer (as a result of the freezing and high temperature extrusion process our products go through). But even if they weren't dead, consumers could "take cells directly from our bioreactor and eat them with a spoon" and still rest assured that they'd be safe.
