New RNA Therapy Enhances Heart Healing, Reduces Scarring

3/29/2026

Summary

Story summary

Columbia University researchers developed an RNA-based therapy that prompts tissues to produce a healing molecule and activates in the heart, eliminating the need for invasive procedures.
In preclinical studies, a single injection improved heart function and reduced scar tissue for four weeks.
The therapy remains effective even when given after significant damage.
Future trials will explore its potential for treating other conditions, including kidney disease and high blood pressure.
