Scientists in Japan have used cardiac muscle cells derived from the stem cells of a macaque to mend the damaged hearts of five other monkeys.

The technique shows that using donor stem cells might one day be a viable way to regenerate the organs of human heart attack patients – an approach that could dramatically reduce the time and expense of developing individualised stem cell treatments.

While using stem cell therapy to treat conditions like heart problems isn’t new, the technique usually involves cultivating stem cells taken from the patient themselves – which can be very expensive.
