After a heart attack, your heart can become weak to the point that it's no longer able to effectively supply the rest of your body with blood. This means bad times, especially since patients with severe heart failure have to rely on mechanical devices or transplants, but stem cells derived from a patient's own skin could potentially provide a cure.
Researchers have discovered a new brain stem cell, which could have great implications for the future of medicine. The stem cells can form various types of cells, including new brain cells, which could possibly be the key to healing many brain injuries.
Broken bones are never fun, but they're a little more serious for men and women serving in the active military, which is why the University of Georgia-discovered "fracture putty," which can speed up the healing of bone fractures, is so important. Though it may mean spending time in sweet casts like this one.
It's been sixteen years since Edinburgh scientists cloned a sheep and named it Dolly, but their sophomore effort appears even better: they've gone back to the studio and created some new brain tissue. Human brain tissue, that is.
Tracheae (aka windpipes) don't grow on trees. In fact, they don't grow anywhere, which is problematic when it comes to tracheal cancer, but recently surgeons in Switzerland managed to replace a cancerous windpipe with a plastic one made in a laboratory and covered in the recipient's stem cells.
It's a good day to be a mouse with a premature aging disease, as researchers at the University of Pittsburgh Medical Center have discovered that injecting old mice with a bunch of young stem cells can double or triple their lifespans.
If you're still not convinced that stem cells are the future of medicine, try this on for size: Japanese researchers have used them to synthesize a fully functioning organ entirely from scratch.
We're not even at the point where we're allowed to get all up in people's stem cells to help cure diseases, but researchers are already thinking ahead to how we can use stem cells to treat genetic diseases, which should be impossible. Or, it was impossible, until we just did it.
Rats with both type 1 and type 2 diabetes have been completely cured of the disease, using neuronal stem cells that have been modified to produce insulin. This approach should work in humans, too, and all it involves is shoving a needle up your nose into your brain. Yay!
The stem cell research debate included lots of promises about how we would be able to get new body parts grown in a lab, and now it's actually happening. Last month a Swedish cancer patient had this rather gross looking artificial trachea implanted, just after it had been grown in a lab using the man's own stem cells.
