Laboratory-made “biosynthetic” corneas can spur damaged tissue and broken nerves to regenerate, restoring vision in human eyes just as well as donor corneas, according to a two-year study of 10 patients reported in Science Translational Medicine.
A worldwide shortage of donated corneas leaves millions of people likely to go blind each year. Now, researchers in Sweden show that these biosynthetic corneas made with human collagen may allow patients who need corneal transplants but do not have donors to regain normal sight.
Researchers have figured out a way to grow a ready-made supply of blood vessels for transplant into patients undergoing heart surgery, reports a new study in the journal Science Translational Medicine.
The blood vessels, or “vascular grafts,” can be made ahead of time, so surgeons can grab them off the shelf when patients need them. Until now, no other vascular graft engineered from human tissue has tolerated simple storage.
