For the first time ever, biologists have regenerated an organ in a living animal. They did so by manipulating a single protein in elderly mice that makes their bodies rebuild their thymuses, an organ of the immune system. It's the first time an organ has been repaired with a chemical trigger and not via stem cell… » 4/10/14 9:30am 4/10/14 9:30am

Medical breakthrough could lead to functional artificial skin

Swiss researchers have achieved a major breakthrough in the development of bioengineered skin. The new grafts, which are about to undergo clinical trials, work a lot like the real thing — because they actually contain functioning blood vessels and lymph capillaries. » 1/30/14 1:49pm 1/30/14 1:49pm

Breakthrough: Scientists build a beating mouse heart with human tissue

In a major scientific first, a team of developmental biologists has built a functional mouse heart from human tissues. The results herald a future where specific patches of heart muscle – or even the whole organ – could be grown for transplantation. » 8/14/13 9:20am 8/14/13 9:20am

Toddler with bioengineered windpipe dies three months after surgery

Two year-old Hannah Warren passed away this past Saturday at the Children’s Hospital of Illinois. Born without a trachea, she was the youngest recipient of a bioengineered organ — one that was grown from her very own stem cells. She will be remembered as a pioneer in regenerative medicine. » 7/09/13 2:39pm 7/09/13 2:39pm

10 mindblowingly futuristic technologies that will appear by the 2030s

Two decades is not a lot in the grand scheme of things, but owing to accelerating change we can expect to see the emergence of some fairly disruptive technological innovations in the coming years. Here are 10 mindblowingly futurist technologies that should appear by the 2030s. » 7/05/13 10:00am 7/05/13 10:00am

How to grow a human heart in three (relatively) easy steps

The day is fast approaching when scientists will finally be able to reconstruct a person's heart from a clump of cells and a simple scaffold. We're not there yet, but this video will show you how it's done. » 7/04/13 6:30am 7/04/13 6:30am

Paralyzed dogs walk again after nose cell transplants

A 10-year old dachshund named Jasper has regained the use of his hind legs after being injected with cells grown from the lining of his nose — cells that are showing a remarkable potential to replace damaged nerves. The procedure, which was conducted on a total of 23 dogs, is set to revolutionize the way spinal cord… » 11/19/12 3:30pm 11/19/12 3:30pm

Researchers remove extra chromosome from Down’s syndrome cells. Could…

Scientists from the University of Washington have successfully removed an extra copy of chromosome 21 in cell cultures belonging to a person with Down's syndrome. While the breakthrough is unlikely to result in an outright treatment for the condition, it could pave the way for gene therapies in which many of the… » 11/12/12 3:02pm 11/12/12 3:02pm

Breakthrough: Researchers can now create an animal entirely from stem…

Biotechnology is getting into some pretty interesting territory these days. The latest breakthrough comes from Kyoto University where research scientists have, for the first time, created a mouse by using eggs produced by stem cells alone. The achievement once again shows the remarkable possibilities presented by… » 10/11/12 1:45pm 10/11/12 1:45pm

Scientists discover stem cells responsible for big brains and higher…

Neuroscientists from The Scripps Institute have identified a specialized population of stem cells that have an impressive vocational calling: higher brain functioning. It's an important finding that holds promise for the treatments of serious cognitive disorders — including those that impact on conscious function. And … » 8/10/12 11:43am 8/10/12 11:43am

Human stem cells restore memory in animals with Alzheimer’s disease

For the first time ever, human stem cells have been shown to have a significant effect on restoring memory in animals suffering from Alzheimer's disease. The breakthrough could have profound implications for the treatment of the age-related disorder, which affects as many as 5.3 million Americans and threatens to… » 7/24/12 4:20pm 7/24/12 4:20pm
