OPTIMIZED METHOD OF BOVINE PERICARDIUM DECELLULARIZATION FOR TISSUE ENGINEERING.

Area of Science:

• Biomaterials science
• Tissue engineering
• Cardiovascular surgery

Background:

• Developing biocompatible scaffolds is crucial for cardiac tissue regeneration.
• Effective decellularization preserves extracellular matrix integrity for bioimplant applications.

Purpose of the Study:

• To evaluate the efficacy of low-concentration sodium dodecyl sulfate (SDS) and EDC/NHS cross-linking for pericardial tissue decellularization.
• To assess the suitability of the resulting scaffold for cardiac surgery bioimplants.

Main Methods:

• Bovine pericardial sacs were decellularized using 0.1% SDS with EDC/NHS cross-linking.
• Histological, molecular genetic, and biomechanical analyses were performed.
• In vitro cytotoxicity and biocompatibility tests were conducted.

Main Results:

• High purification of the extracellular matrix was achieved.
• Scaffold structure-function properties were maintained or improved post-decellularization.
• The scaffold demonstrated no cytotoxicity to human fibroblasts and showed successful biointegration in animal models.

Conclusions:

• Decellularization using 0.1% SDS with NHS/EDC cross-linking is a viable method for producing tissue-engineered materials.
• This technique shows promise for manufacturing bioimplants in cardiac surgery.
