Islet transplantation has become an enticing answer for a better Band-Aid in treating diabetes, both type 1 and 2. In type 1 diabetes the problem is the destruction of islets. About 15% of those with type 2 diabetes have the same problem of islet destruction, just as in type 1 diabetes. The age old problem with all transplanted cells is the recipient's immunity rejecting them as foreign bodies. Look no further than the ocean blue for a promising resolution.

Cerco Medical is developing a better Band-Aid to treat diabetes with a seaweed encapsulation technology. Their method uses a thin-sheet of encapsulated islets that is surgically attached to the liver. The sheet of islets is thinly coated with kelp to prevent immune rejection, and allow the islets to release insulin without allowing T-cells to enter and destroy the islets. This is a promising technique to potentially restore normal blood sugar control in diabetes.

Of course, the biomedical industry is quickly becoming the next dot-com. So the islet shortage is not a concern. With the advent of remarkable technologies, we can conceivably generate our own islets without having to sacrifice fetuses, wait for islet donors to die, or slaughter Billy Bob's best porker. The future of the better Band-Aid is closer than we think!
