Researchers Find Cell That Replenishes Heart Muscle

June 23, 2015

(Medical Xpress) – Regenerative medicine researchers at UT Southwestern Medical Center have identified a cell that replenishes adult heart muscle by using a new cell lineage-tracing technique they devised. Adult heart muscle is comprised of cells called cardiomyocytes. Most cardiomyocytes don’t replenish themselves after a heart attack or other significant heart muscle damage. The UT Southwestern researchers were able to devise a new cell-tracing technique, allowing them to detect cells that do replenish themselves after being damaged.
