Replacing Body Parts
Custom-made hearts, lungs, kidneys, and other organs could revolutionize organ transplantation. Scientists are learning how to grow custom-made body parts so they can be ready when you—and your vital organs—start falling apart. At the University of Minnesota, Doris Taylor and her colleagues strip organs of their cells, reseed the organ “skeletons” with living cells, and watch as the organs start working right in front of their eyes.

Real benefits for biologists—if they do it right
Stem-Cell Blogger October 2009 was a tough month for Paul Knoepfler. First, Nature shut down one of his favorite blogs, the Niche, which he had followed avidly in his work as a stem-cell researcher at UC Davis. Worse, he was diagnosed with aggressive prostate cancer at the age of 42. Paul wrote a fascinating editorial in Nature about how his battle with cancer gave him the courage to start blogging about stem cells. “After all, how hard can blogging be when compared with facing cancer?” he asked. It turns out that biologists are often extremely reluctant to blog about their work. They fret that they’ll antagonize adversaries, court needless controversy, publish errors that have to…

Reminder of Hope for Damaged Hearts on Valentine’s Day
Stem Cell Therapy Could Regenerate Damaged Heart Muscle After Heart Attacks A promising stem cell therapy approach could soon provide a way to regenerate heart muscle damaged by heart attacks. Researchers at Cedars-Sinai Heart Institute and The Johns Hopkins University harvested stem cells from the hearts of 17 heart attack patients and after prepping the cells, infused them back into the patients’ hearts. Their study is published in the current issue of The Lancet. The patients received the stem cell infusions about three months after their heart attacks. Researchers found that six months after treatment, patients had significantly less scarring of the heart muscle and also showed a considerable increase the amount of healthy heart…

Stem Cell Line Placed On National Registry for Researchers
The University of Michigan’s first human embryonic stem cell line will be placed on the U.S. National Institutes of Health’s registry, making the cells available for federally-funded research. It is the first of the stem cell lines derived at the University of Michigan to be placed on the registry. The line, known as UM4-6, is a genetically normal line, derived in October 2010 from a cluster of about 30 cells removed from a donated five-day-old embryo roughly the size of the period at the end of this sentence. That embryo was created for reproduction but was no longer needed for that purpose and was therefore about to be discarded. U-M is among just a handful…

More Results in for Autologous Heart Cells
Cardiac stem-cells increase viable myocardium post-MI: CADUCEUS Authors of a small study using cardiac-derived stem cells in “convalescent” MI patients say they’ve uncovered some of the first true evidence that the heart can regenerate, describing a new method that, they say, led to “unprecedented” improvements in viable heart muscle . Results of the CADUCEUS study, published online February 13, 2012 in the Lancet, showed not only that scar size was reduced on MRI at six months—something also seen in previous research—but also that the amount of viable heart mass and regional contractility were also improved. Dr Raj R Makkar (Cedars-Sinai Heart Institute, Los Angeles, CA) and colleagues used a proprietary technique to harvest autologous heart…

Texas Medical Board Moves to Regulate Adult Stem Cell Use
AUSTIN – The Texas Medical Board Friday approved a tentative policy regulating the use of adult stem cells, the experimental therapy Gov. Rick Perry drew criticism for undergoing for his ailing back last year. “This policy will afford the public protection that doesn’t exist now for products not approved by the Food and Drug Administration,” said Dr. Irwin Zeitler, president of the board. “At the same time, it doesn’t hinder progress. Hundreds of studies have shown the promise of adult stem cells.” Under a policy that will come up for final approval April 13, Texas doctors would be authorized to provide stem cell therapy only if an independent review committee that assesses research trials for patient safety grants permission. The…

Heart Stop Beating Premiers at Sundance
Two Houston surgeons have successfully implanted the world’s first continuous-flow artificial heart in a human patient, a significant advance that promises a smaller and much more durable alternative to existing artificial hearts. Drs. Bud Frazier and Billy Cohn took out the dead heart of 55-year-old Craig A. Lewis on March 10 at the Texas Heart Institute. After harmful proteins built up in his heart to the point it could no longer work, Lewis lived only with the aid of external breathing, dialysis and heart support machines. The Houston man had maybe a day to live when Frazier and Cohn were given the opportunity to test their device — a pair of turbines cobbled together to…
Leading the Texans’ Fight Against Heart Disease
James T. Willerson describes himself as a proud Texan. He was born in the small town of Lampasas, grew up in San Antonio, studied in Austin, and has spent the majority of his medical career in Dallas and Houston—save for five years training in Boston and two at the National Institutes of Health, Bethesda, MD. Despite his strong attachment to the Lone Star State, however, his contribution to cardiovascular science is world-renowned. Indeed, in addition to his long list of U.S. honors, which include membership of the Institute of Medicine of the National Academy of Sciences, a Distinguished Scientist Award from the American College of Cardiology, and both Distinguished Scientist and Gold Heart Awards from…

New Children’s Research Institute at UTSW Breakthrough
Scientists with the new Children’s Research Institute at UT Southwestern Medical Center have identified the environment in which blood-forming stem cells survive and thrive within the body, an important step toward increasing the safety and effectiveness of bone-marrow transplantation. Institute investigators led by Dr. Sean Morrison asked which cells are responsible for the microenvironment that nurtures haematopoietic stem cells, which produce billions of new blood cells every day. The answer: endothelial and perivascular cells, which line blood vessels. “Although scientists have searched for decades to identify the stem cell home, this is the first study to reveal the cells that are functionally responsible for the maintenance of blood-forming stem cells in the body,” said Dr….

Synthetic Windpipe Used to Replace Cancerous One
Surgeons in Sweden have replaced the cancerous windpipe of a Maryland man with one made in a laboratory and seeded with the man’s cells. A trachea made from plastic, above, and seeded with stem cells was successfully implanted in a Baltimore man in Sweden. The windpipe, or trachea, made from minuscule plastic fibers and covered in stem cells taken from the man’s bone marrow, was implanted in November. The patient, Christopher Lyles, 30, whose tracheal cancer had progressed to the point where it was considered inoperable, arrived home in Baltimore on Wednesday. It was the second procedure of its kind and the first for an American. Dr. Macchiarini is a leader in the field of…
