The U.S. Department of Agriculture has approved the sale of cell-cultured chicken for two companies. Upside Foods and Good Meat, a subsidiary of Eat Just, received the approval to sell lab-grown protein. Cultured meat is made by putting stem cells from the fat or muscle of an animal into a culture medium that will feed them and allow them to grow. The medium is then put into a bioreactor that supports the growth and churns out a product that looks and tastes like traditional meat.
