While short-term aspirin use after a stroke or heart attack has clear benefits, the authors say that patients over 75 who take aspirin on a daily basis should be prescribed a proton-pump inhibitor (heartburn drugs) to reduce the risk of bleeding. Roughly 40-60% of adults aged 75 or older in […]

Patients with severe and end-stage heart failure have few treatment options available to them apart from transplants and “miraculous” stem cell therapy. But a new Tel Aviv University study finds that stem cell therapy may, in fact, harm heart disease patients. The research, led by Prof. Jonathan Leor of TAU's […]

Scientists have shown how the precursors of egg and sperm cells – the cells that are key to the preservation of a species – arise in the early embryo by studying pig embryos alongside human stem cells. In research published in Nature, researchers at the University of Cambridge and the […]

Researchers at the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR have engineered a three-dimensional heart tissue from human stem cells to test the safety and efficacy of new drugs on the heart. “Cardiotoxicity, which can lead to heart failure and even death, is a major cause of drug withdrawal […]

University of Rochester Medical Center researchers have discovered that loss of muscle stem cells is the main driving force behind muscle decline in old age in mice. Their finding challenges the current prevailing theory that age-related muscle decline is primarily caused by loss of motor neurons. Study authors hope to […]

Ophir Klein is growing teeth, which is just slightly less odd than what Jeffrey Bush is growing – tissues that make up the face. Jason Pomerantz is growing muscle; Sarah Knox is growing salivary glands; and Edward Hsiao is printing 3-D bone using a machine that looks about as complex as […]

Whether using embryonic or adult stem cells, coercing these master cells to convert to the desired target cell and reproduce flawlessly is difficult. Now an international team of researchers has a two-part system that can convert the cells to the targets and then remove the remnants of that conversion, leaving […]

Researchers at UC San Francisco have found that older people with persistent pain show quicker declines in memory as they age and are more likely to have dementia years later, an indication that chronic pain could somehow be related to changes in the brain that contribute to dementia. The study, […]
