# RETRACTION: Human Umbilical Cord Mesenchymal Stem Cell‐Derived Exosomes Combined With Gelatin Methacryloyl Hydrogel to Promote Fractional Laser Injury Wound Healing

## TL;DR

This retracted paper claimed that exosomes from stem cells combined with a hydrogel helped heal laser-induced wounds in humans.

## Contribution

The study purported to introduce a novel wound-healing strategy using stem cell-derived exosomes and a hydrogel.

## Key findings

- The paper reported that the exosome-hydrogel combination improved wound healing in a fractional laser injury model.
- It suggested that the treatment enhanced tissue regeneration and reduced inflammation.
- However, the findings were later invalidated due to a compromised peer review process.
