"A patch that reinforces the heart after a heart attack seemed to work well in a recent clinical trial involving pigs. How will it work in humans?"

"Researchers at Emory University School of Medicine and Children's Healthcare of Atlanta have been using space-simulation machines to enhance the ability of pluripotent stem cells to turn into cardiac muscle cells. Now they – or the cells they've carefully cultured, at least -- will get the chance to try the real thing on the International Space Station."

"Cardiac stem cell therapy is a promising treatment for damaged hearts. However, researchers are still working on two major issues with the therapy – how to keep the stem cells in place and how to prevent rejection when the stem cells are not from the patient’s own body. A new approach from NC State researcher Ke Cheng and a team of international collaborators may solve both of these problems."

"A Clemson researcher thinks injecting stem cells into dying hearts might be a breakthrough therapy for heart failure patients, and the National Institutes of Health is backing him up with a $1.5 million grant."

"Using stem cells derived from the umbilical cord, researchers have improved the heart muscle and function of heart failure patients, paving the way for noninvasive therapies."

"Heart-attack damage could be repaired with stem cells and tiny “nanowires” as part of a new research project that involves all three of South Carolina’s major research universities and is backed by $1.5 million from the National Institutes of Health."

"The team from Imperial College London have developed a silicon chip with tiny grooves, which are 0.01 millimetres wide and only 0.0003 millimetres deep. They showed that the grooves stimulated a biochemical response in the cardiac stem cells that helps switch them into cardiomyocytes, which are the muscle cells that make up most of the heart."

"After a year, patients who were treated with a new method for delivering stem cells to damaged heart muscle showed a modest improvement in the heart's pumping ability."

"First doctors extracted bone marrow from Palmer's hip and separated white blood cells from it. Stem cells were then extracted from the white blood cells, which were injected into his heart muscle. This began a process of tissue regeneration which has now strengthened the muscle considerably."

"A new study published in STEM CELLS Translational Medicine demonstrates how mesenchymal stem cells (MSCs) not only protect the heart from further damage after a cardiac incident but can actually slow down its aging process, too. These findings, in a rat model of the aging heart, could help propel stem cells to the forefront as a potential solution for more effective ways to treat heart conditions."
