Human Stem Cells Give Monkey Hearts a Boost After Heart Attacks, Study Says

July 3, 2018

(CNN) – Following heart attacks, a handful of monkeys regained some of the pumping ability their hearts had lost after being given human embryonic stem cells, according to a study published Monday in Nature Biotechnology. Scientists have tried for years to develop a stem cell treatment for heart disease caused by lack of blood flow, which contributed to more than 9.4 million deaths worldwide in 2016, according to the World Health Organization.
