So the ECM in my skin is different than the ECM in my liver, and the ECM in different parts of the same organ actually vary, so it's very difficult to be able to have a product that will react to the local extracellular matrix, which is exactly what we're trying to do.
就是说，我皮肤上的细胞外基质 与我肝脏细胞外基质是不同的， 并且在同样的器官中细胞外基质 实际上也会有不同，所以很难实现 生产一种产品 可以跟不同部位的细胞外基质产生反应， 而这正是我们正尝试去做的事情。
