Kind: research · Impact: medium

## In brief

- An experimental mRNA therapy reportedly prompts heart muscle cells to start dividing and help repair damage after a heart attack, based on animal studies.
- Scientists describe the treatment as one that 'reawakens' heart muscle cells so they divide and help repair damaged muscle.
- The reported evidence comes from animals; the source does not describe human trials.

## Why it matters

Adult heart muscle cells normally barely regenerate after a heart attack, so a therapy that induces division in animals addresses a central limitation of current cardiac repair, though human effectiveness and safety remain untested in the source.
