By manipulating stem cells, scientists from the Gladstone Institutes and UC Berkeley have found they can grow beating cardiac tissue in a petri dish. The cells "self-organized" to form microchambers, which slowly began to beat like a full-sized heart.
Dr. Steven Finkbeiner is part of the Neurocollaborative, an initiative that is creating stem cell lines from ALS patients that will mimic their own nerve cells and received money from the Ice Bucket challenge.
Researchers have used stem cells to create a tiny, beating heart - and say it could revolutionise medicine. The new hearts will allow new drugs to be tested, and give researchers a new insight into how the heart develops.
Dr. Bruce Conklin, a stem cell biologist at the Gladstone Institute of Cardiovascular Disease in San Francisco, along with colleagues from UC Berkeley, developed tiny hearts using stem cells derived from skin tissue.
Stem cells, the jack-of-all-trades building blocks of human tissues, have yet another application in biology research: scientists have been able to grow them into beating cardiac tissue. This could help scientists better understand how the heart develops and test if drugs might be affect cardiac development in growing fetuses.
Researchers from the Gladstone Institutes and UC Berkeley grew beating heart tissue from stem cells—creating a mini human heart chamber in a dish. The new technology could be used to test drugs that are likely to be dangerous for pregnant women and cause heart defects in the fetus.

Grateful Dead drummer Mickey Hart is working with Deepak Srivastava to record and interpret the sounds of heart cells. By listening to cells, Hart and Srivastava hope to distinguish between healthy and damaged hearts.
New research builds on a key discovery Katie Pollard made in 2006 of short DNA sequences that evolved more rapidly in humans than in our closest relatives. Now it appears these sequences increase brain size, one of the key features that distinguish humans and apes.
Dr. Robert Grant writes in the the Huffington Post about ending HIV transmission using the successful strategies of prenatal HIV care.
