Human 'Mini Hearts' Made in Lab
Living “mini hearts” — structures that resemble tiny, primitive, beating hearts — can be created from human stem cells, researchers say.
These miniature heartlike structures could help scientists test heart drugs for safety, and learn more about how the heart develops in order to help prevent defects, investigators added.
“It might even be possible to grow pieces of heart to serve as patches during heart surgery, but that’s a long way off,” study co-senior author Dr. Bruce Conklin, a physician and stem cell biologist at the Gladstone Institute of Cardiovascular Disease in San Francisco, told Live Science. Researchers could also use these structures as models for fixing damaged hearts, he said.
