Curcumin-Primed Stem Cells Boosted Heart Function in Old Rats
Graded Preliminary — cell experiments and a study in aged rats across five treatment groups, with no sample size given, so the finding has not been tested in people.
Animal study. Findings may not carry over to people, which is why the grade is capped at Preliminary.

This early animal work suggests curcumin may help stem cells survive, but says nothing about supplements.
Old rats given stem cells that had been soaked in curcumin beforehand showed better heart function than rats given plain stem cells. The curcumin appeared to make the transplanted cells hardier by switching on a survival signal. A specific microRNA called miR-3575 seemed to drive the effect, since blocking it wiped out the benefit. This is early lab work in animals, not a case for taking curcumin pills for your heart.
