Scientists developed a new way to grow steak-like meat in the laboratory using mushroom scaffolds. They used edible oyster mushrooms (Pleurotus ferulae) that were treated to remove all cells while keeping the fibrous structure intact. This mushroom scaffold provided the perfect environment for cow muscle cells to grow and organize into meat-like tissue. The resulting cultured meat had texture and appearance similar to real beef, offering a sustainable alternative to traditional livestock farming.
