In this case, mouse bone marrow stem cells grew into cells that produce the cornea protein keratocan. 在这种情况下，老鼠骨髓干细胞长成能够产生眼角膜蛋白质的细胞。
If we can change the function of non-corneal bone marrow stem cells by introducing them into human corneas, we can possibly repair the loss of isual sharpness caused by mutations. 如果将非角膜骨髓干细胞引入到人类角膜能够改变它们的功能，我们也许能够修复由于突变造成的视觉敏锐性的丧失。
