Producing cultivated meat requires isolating muscle stem cells — the building blocks of muscle tissue — from animal samples. But doing so at scale often depends on collagenase, an expensive enzyme used to break down tissue. Researchers at Chungbuk National University may have found a simpler, natural alternative that could make the process both cheaper and cleaner.
What the Patent RevealsThe newly published patent describes a method of isolating muscle satellite cells (the stem cells responsible for muscle growth) using natural proteases — enzymes found in fruits like kiwi, papaya, and pineapple. These fruit-derived enzymes gently separate the cells from the surrounding tissue, allowing them to be cultured and multiplied in a lab environment. The result: a lower-cost, food-safe, and readily available substitute for collagenase in cultivated meat production. (KR20250093169A)
