Area of Science:

Biomaterials Science
Regenerative Medicine
Otolaryngology

Background:

Decellularized tissues serve as scaffolds for organ regeneration.
The larynx is a complex organ with limited regenerative capacity.
Developing effective laryngeal scaffolds is crucial for reconstructive surgery.

Purpose of the Study:

To establish a perfusion decellularization protocol for creating a 3D whole laryngeal extracellular matrix (ECM) scaffold.
To evaluate the feasibility and reproducibility of the protocol in a rabbit model.

Main Methods:

Harvesting rabbit larynges for decellularization.
Implementing a perfusion-based decellularization protocol.
Performing histological, molecular, cellular, and scanning electron microscopy analyses.

Main Results:

The protocol effectively removed cellular components while preserving the ECM and cartilage structure.
DNA content was significantly reduced in decellularized larynges compared to native ones (e.g., 57.2% reduction in cartilage).
Histological analysis confirmed the absence of cells and the integrity of the extracellular matrix.

Conclusions:

The developed perfusion decellularization protocol is feasible and reproducible.
This protocol successfully generates a 3D whole laryngeal ECM scaffold in a rabbit model.
The resulting scaffold holds potential for future laryngeal tissue engineering and regeneration applications.
