"Reprogrammed" Stem Cells Approved to Mend Human Hearts in Pilot Study
“Reprogrammed” Stem Cells Approved to Mend Human Hearts in Pilot Study
Three patients in Japan will receive the experimental therapy in the next year
By David Cyranoski, Nature magazine on May 30, 2018
Scientists in Japan now have permission to treat people who have heart disease with cells produced by a revolutionary reprogramming technique. The study is only the second clinical application of induced pluripotent stem (iPS) cells. These are created by inducing the cells of body tissues such as skin and blood to revert to an embryonic-like state, from which they can develop into other cell types.
On 16 May, Japan’s health ministry gave doctors the green light to take wafer-thin sheets of tissue derived from iPS cells and graft them onto diseased human hearts. The team, led by cardiac surgeon Yoshiki Sawa at Osaka University, says that the tissue sheets can help to regenerate the organ’s muscle when it becomes damaged, a symptom of heart disease that can be caused by a build-up of plaque or by a heart attack.
“It will excite worldwide attention, as many groups are working in the same direction,” says Thomas Eschenhagen, a pharmacologist at the University of Hamburg in Germany and chair of the German Centre for Cardiovascular Research.
