With new advancements happening on a regular basis in the world of bioprinting, it’s hard to determine just which company is furthest ahead. Is it Organovo, the publicly traded company already working to create 3D printed mini kidneys with Australian researchers? Or is it one of the many research institutions making advancements in 3D printing ear drums, blood vessels, or carbon composites for bone regeneration? If one had to choose, they might lean towards 3D Bioprinting Solutions, who successfully 3D printed a thyroid gland, classified as an “organ construct”. And, today, news leaked that the Russian company had taken their research one step further, implanting a 3D printed thyroid into mice.
Taking the pill when a heart attack occurs, the muscles and blood vessels around the organ could rebuild themselves.
Researchers in Britain claim they may be just a decade away from perfecting a way to persuade the heart to rejuvenate – a process thought to be impossible just five years ago. They have developed a pill that triggers the heart to repair itself after an attack and is a major step towards one of the “holy grails” of medical research.
The ultimate goal is to provide a solution to the shortage of donor livers available for patients who need transplants.
Researchers at the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center have reached an early, but important, milestone in the quest to grow replacement livers in the lab. They are the first to use human liver cells to successfully engineer miniature livers that function – at least in a laboratory setting – like human livers. The next step is to see if the livers will continue to function after transplantation in an animal model.
The Food and Drug Administration has cleared the way for the world’s first study of human embryonic stem cell therapy, Geron Corp said on Friday.
A patient’s collapsed lung, at right, is seen prior to a windpipe transplant which used tissue grown from the patient’s own stem cells.
Doctors have given a woman a new windpipe with tissue grown from her own stem cells, eliminating the need for anti-rejection drugs. “This technique has great promise,” said Dr. Eric Genden, who did a similar transplant in 2005 at Mount Sinai Hospital in New York. That operation used both donor and recipient tissue. Only a handful of windpipe, or trachea, transplants have ever been done.
The technology is the same as that of the simple inkjet printer found in homes and offices, but Japanese scientist Makoto Nakamura is on a mission to see if it can also produce human organs.
This device lets surgeons attach small anchors to tissue inside a beating heart by compensating for the heart’s movement.
Fixing the heart is hard. Certain procedures have to be performed on a stationary organ, so the heart is stopped and the patient put on a cardiopulmonary bypass machine. But stopping the heart increases the risk of brain damage. Now researchers at Harvard University and Children’s Hospital Boston are testing a robotic system that could help surgeons perform a common valve repair while the heart beats on. The system uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a patient’s mitral valve as it moves.
The final countdown
Strange instrument, even stranger vocalist. It combines a tiny piano with a ukulele and a kazoo. Even stranger instrument video after the jump
A Wild Combination
We love people who take common everyday items you might find at a garage sale, and then turn them into something with real artistic appeal. Canadian artist Graeme Patterson has done just that with his whimsical Hockey Organ, combining an old table hockey game, a 1980s era Casio electronic keyboard, and other assorted bits to recreate the look and feel of a live event. The keyboard has been hacked so that each note moves a different player on the rink, resulting in totally unpredictable on ice action, while your music plays through speakers.

Technological developments in the field of software, communication and medicine have prompted and encouraged growth in the field of bionics.
The UK government must bring in presumed consent to organ donation or allow a controlled donor compensation program for unrelated live donors, in order to bring the “inhumane” practice of transplant tourism from the UK to an end, claims a doctor.
Harvesting organs is big business in NYC
Saving the living has always been the No. 1 priority for a New York City ambulance crew. But a select group of paramedics may soon have a different task altogether: saving the dead.
The city is considering creating a special ambulance whose crew would rush to collect the newly deceased and preserve the body so that the organs might be taken for transplant.
