Stowers scientists discover new rules about how flatworm stem cells regrow body parts, offering insights into potential tissue repair and regenerative medicine in humans.

KANSAS CITY, Mo. , Oct. 15, 2025 /PRNewswire/ -- Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research reveals planarian stem cells ignore their nearest neighbors and instead respond to signals further away in the body. This discovery may help explain the flatworm's extraordinary ability to regenerate — and could offer clues for developing new ways to replace or repair tissues in humans.

The study , published in Cell Reports on October 15, 2025, and led by Postdoctoral Research Associate Frederick "Biff" Mann, Ph.D., from the lab
