Abstract
US patents relating to compositions containing extracellular matrix material and methods of using extracellular material in tissue engineering and regenerative medicine are being granted at rapid pace. This article briefly describes some of these US patents and their claims. The large number of patents being issued on extracellular material and its uses indicates that there remains strong commercial interest and innovation in this area of tissue engineering and regenerative medicine.
